sammy is eleven less than five times Jaime's age. if the sum of their ages is 55, how old is each girl? please help me if i dont get this done soon moms gonna be super mad
Answer:
Jaime = 11
Sammy = 44
Step-by-step explanation:
It is given that Sammy is eleven less than five times Jaime's age. Use parameter (S) to represent Sammy's age, and parameter (J) to represent Jaime's age. Form an equation based on this given information:
S = 5J - 11
It is given that the sum of the two girl's ages is (55), use an equation to represent this.
S + J = 55
Substitute in the expression for the value of (S) in terms of (J),
(5J - 11) + J = 55
Simplify,
6J - 11 = 55
Inverse operations,
6J - 11 = 55
6J = 66
J = 11
Backsolve for the value of (S), substitute in the value of (J) into the equation for (S) and solve,
S = 5(J) - 11
S = 5(11) -11
S = 55 - 11
S = 44

Find the Value of x ( All help would be appreciated )
Answer:
Hello! answer: x = 31
Step-by-step explanation:
This whole thing Will equal 360 we can subtract that by 112 and another 112 because there are two because they are vertical angles so 112 + 112 = 224 360 - 224 = 136 now we divide by 2 since those last two angles will have the same measure 136 ÷ 2 = 68 so now we just have to find out what multiplied by 2 plus 6 = 68 so 2 × 31 = 62 and 62 + 6 = 68 so x = 31 hope that helps! and I showed a visual for you so hopefully this makes more sense!

Tim has already earned $30 mowing lawns. He earns $10 per lawn. Write and solve an inequality to determine how many more lawns he will have to mow to have at least $75 for a new lawnmower. Interpret the solution.
Answer:
Tim needs to mow 5 more lawns in order to buy his new lawnmower
Step-by-step explanation:
1) Tim has already mowed $30 worth of lawns
2) Tim makes $10 per mow
4) Tim needs to make $75 total for his new mower
5) $75 - $30 = $45
6) Tim needs to make $45 in order to get his new mower
7) 5 x 10 = 50
8) Tim needs to mow 5 lawns in order to make over $45
9) If Tim only mowed 4 lawns he would make $40 and still be $5 short

Which graph represents a function with a domain of all real numbers greater than or equal to -7 and less than 2?
Step-by-step explanation:
The probability that roger wins a tennis tournament (event a) is 0.45, and the probability that Stephan wins the tournament (event B) is 0.40. The probability of Roger winning the tournament, given that Stephan wins, is 0. The probability of Stephan winning the tournament given that Roger wins, is 0. Given this information, which statement s true?
Answer:
3.Events A and B are not independent because P(A|B) ≠ P(A).
Step-by-step explanation:
Given this information, which statement is true?
1.Events A and B are independent because P(A|B) = P(A).
2.Events A and B are independent because P(A|B) ≠ P(A).
3.Events A and B are not independent because P(A|B) ≠ P(A).
4.Events A and B are not independent because P(A|B) = P(A).
Solution:
Two events A and B are independent if A occurring does not change the probability of B. For independent events:
P(A ∩ B) = P(A) * P(B)
Hence: P(A/B) = P(A ∩ B) / P(B) = P(A) * P(B) / P(B) = P(A)
Let event A represent the probability that roger wins a tennis tournament and event B represent the probability that Stephan wins a tennis tournament.
Therefore:
P(A) = 0.45, P(B) = 0.4
The probability of Roger winning the tournament, given that Stephan wins, is 0. Hence, P(A/B) = 0
P(A/B) = P(A∩B) / P(B)
0 = P(A∩B) / 0.4
P(A∩B) = 0
The probability of Stephan winning the tournament given that Roger wins, is 0. Hence P(B/A) = 0
P(B/A) = P(B∩A) / P(A)
0 = P(B∩A) / 0.4
P(B∩A) = 0
Therefore since P(A∩B) = P(B∩A) =0, this means that event A and event B are mutually exclusive. That is both events cannot occur at the same time.
Events A and B are not independent because P(A|B) ≠ P(A).

1. If x and y are supplementary angles, then y is acute.
2. If x and y are complementary angles, then x is obtuse.
Answer:
1. If x and y are supplementary angles, then y is sometimes acute because supplementary angles are angles that add up to 180 degrees. So, y can be acute while x can be obtuse, y can be obtuse while x can be acute, or both can be right angles.
2. If x and y are complementary angles, then x is never obtuse. Complementary angles are angles that add up to 90 degrees, and obtuse angles are angles over 90 degrees, so it's impossible to have an obtuse angle as a complementary angle.
Step-by-step explanation:
Answer:
1) Sometimes
2) Never
Step-by-step explanation:
1) you could have two angles add up to 180 degrees and one of them could be less than 90
example, x = 140° and y = 40°
2) if two angles are complementary then their sum is 90° so neither angle must be less than 90°, thereby making them both acute angles

Here are two stories: The initial freshman class at a college is 10% smaller than last year’s class. But then during the first week of classes, 20 more students enroll. There are then 830 students in the freshman class.
A store reduces the price of a computer by $20. Then during a 10% off sale, a customer pays $830
here are two equations: 0.9x+20=830, 0.9(x-20)=830
A. Decide which equation represents each story.
B. Explain why one equation has parentheses and the other doesn't.
C.Solve each equation, and explain what was the solution means in the situation.
Thank you to the people that answered my questions!
Using proportions, it is found that:
a. The equations are related to the stories as follows:
0.9x+20=830 = Class in college.0.9(x-20)=830 = Computer price.b. The parenthesis is because of the 10% reduction was applied over the value subtracted by $20.
c. The solutions are given as follows:
x = 900: Size of the freshmen class in the previous year.x = 942: Original price of the computer.What is a proportion?A proportion is a fraction of a total amount, and are used along with basic arithmetic operations such as multiplication or division to find the desired measures in the context of a problem.
One example of application of proportions is for percentage problems, as the decimal equivalent of the percentage, considering discounts or increases, is multiplied by the total amount to find the equivalent amount.
For the college class, we have that:
It is 10% smaller than last year's amount of x, that is, 90% of x = 0.9x.Then 20 is added to this amount, that is, 0.9x + 20.The equivalent amount is of 830 students, hence the equation is:
0.9x + 20 = 830
The solution is found as follows:
0.9x = 810
x = 810/0.9
x = 900.
Which is the size of the freshmen class in the previous year.
For the computer in the store, we have that:
The price of x was reduced by $20, hence x - 20.Over the price reduced by $20, a reduction of 10% was applied, hence the price paid is of: 0.9(x - 20).This price is of 830, hence the equation is:
0.9(x - 20) = 830
The solution, which is the initial price of the computer, is found as follows:
x - 20 = 830/0.9
x = 20 + 922
x = 942.

Mike is training for a cross country bike ride. He rides his bike 60 miles, 66 miles, 70 miles, 60 miles, and 51 miles on the first five days of his training. How many miles does he need to ride on day 6 to average(mean) of 59 miles per day?
Answer:
47 miles
Step-by-step explanation:
The formula for Mean = Sum of values/Number of values
Number of values is 6
From the above question, we are only given 5 values,
The 6th value is represent as= x
Hence,
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles/6 = 59 miles
Cross Multiply
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles = 6 × 59 miles
307 miles + x miles = 354 miles
x miles = 354 miles - 307 miles
x miles = 47 miles
Therefore, the number of miles he need to run on day 6 is 47 miles
A student fit the line shown below to the data in the scatter plot. Which statement about the student's line is true?
A. It is a good fit because there are the same number of points above the line as below it.
B. It is a good fit because all of the points are on or below the line.
C. It is not a good fit because there are no points on the line.
D. It is not a good fit because only one point is on the line.
Answer:
C. It is not a good fit because there are no points on the line.
Step-by-step explanation:
In order for a line to be a good fit for a data set represented as a scatterplot, the line must follow the general trend of the data in the scatterplot. This line does not follow the general trend of the data on the scatterplot, thus option (C) is the best statement to describe the situation.
C. It is not a good fit because there are no points on the line.
