An angle measures 52° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
64º and 116º
Step-by-step explanation:
x + (x - 52) = 1080
2x - 52 = 180
2x = 232
x = 116º
x - 52 = 64º
What is the answer to the question, 5(x+2) = 11?
Answer:
Solution given:
5(x+2) = 11
dividing both side by 5
5(x+2)/5=11/5
x+2=11/5
subtracting both side by 2
x+2-2=11/5-2
x=11/5-2
x={11-2*5}/5[taking l.c m
x={11-10}/5
x=1/5
x=1/5is a required answer.

4. A rental car costs a one time fee of $180 and then an additional $65 for each day it is
rented. If the Neddles family's total bill was $520, how many days did they rent the car?
Answer:
5.23 =d
Step-by-step explanation:
cost = fee + daily charge*days
520 = 180+ 65d
Subtract 180
520 -180 = 180+65f-180
340 = 65d
Divide by 65
340/65 = 65d/65
5.23 =d

The product of -12 and a number is 60
Answer:
-5
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
The result is positive, so you know the number must be negative. What two numbers normally make 60? That would be 5 and 12, but since the 12 is negative (-12), that means the 5 must be negative (-5). So, the answer is -5.

A town has a population of 5600 in 2014. If the towns population increases at an annual rate of 1.8%, determine the towns population in 2020. *
Answer:
In 2020 the population will be 6,233.
Step-by-step explanation:
Giving the following information:
Present value (PV)= 5,600
Growth rate (g)= 1.8%
Number of periods= 6 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 5,600*(1.018^6)
FV= 6,232.67 = 6,233
In 2020 the population will be 6,233.

x = [tex]\frac{-(1)±\sqrt{(-7)^{2} - 4(1)(-8) } }{2(1)}[/tex] (pls ignore the "A" I don't know why it's showing up)
=> x = [tex]\frac{-1±\sqrt{49 + 32} }{2}[/tex]
=> x = [tex]\frac{-1±9 }{2}[/tex]
=> x = [tex]\frac{-1 +9}{2}[/tex] = 4 or [tex]\frac{-1-9}{2}[/tex] = -5 (the answer is only 4 since it's asking for the positive solution)

Find the measure of x and y ?
Answer:
x = 28
y = 47
Step-by-step explanation:
40 + 5x = 180 since it forms a straight line
5x = 180-40
5x = 140
Divide by 5
5x/5 = 140/5
x =28
3y-1 = 5x since they are alternate exterior angles
3y-1 = 140
Add 1
3y = 141
3y/3 = 141/3
y = 47

The faces on a number cube are labled 1,2,2,3,4, and 5the number cube is rolled 114 times how many times would you expect the number 2 to apper
Given:
The faces on a number cube are labeled 1,2,2,3,4, and 5.
The number cube is rolled 114 times.
To find:
How many times would you expect the number 2 to appear?
Solution:
We have,
Total outcomes = 1,2,2,3,4, and 5.
Number of total outcomes = 6
Favorable outcomes = 2 and 2
Number of favorable outcomes = 2
The probability of getting 2 is:
[tex]P(2)=\dfrac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}[/tex]
[tex]P(2)=\dfrac{2}{6}[/tex]
[tex]P(2)=\dfrac{1}{3}[/tex]
Now, the expected number of times when 2 to appear is:
[tex]E(x)=114\times P(2)[/tex]
[tex]E(x)=114\times \dfrac{1}{3}[/tex]
[tex]E(x)=38[/tex]
Therefore, the expected number of times is 38.

[Q] Mike and Jeanie played 38 games of checkers. Mike won 6 more games than Jeanie. To find out how many games Jeanie won a student used this equation.
M + J = 38
In this equation: M = number of games Mike won and J = number of games Jeanie won Which other equation would help the student to solve this problem?
(A) 38 - 6 = J
(B) M - J = 6
(C) 38 + 6 = J
(D) J - M = 6
(E) M + J = 6
Answer:
(B) M - J = 6
Step-by-step explanation:
Here we have the variables:
M = number of games that Mike won.
J = number of games that Jeanie won.
And we know that there is a total of 38 games played, then if a game can not end in a draw, we have the equation:
M + J = 38
Now we want to find the other equation needed to solve this problem:
We also know that Mike won 6 more games than Jeanie, this is written as:
M = J + 6
We can subtract J in both sides to get:
M - J = 6
This is the equation from option B, so we can conclude that the correct option is B.

8. An car can hold 8 1/4 gallons of fuel. It contains 4 5/6 gallons of fuel. How
much more fuel is needed to fill the car?
Answer:
3 5/12
Step-by-step explanation:
Answer:
41/12 gallons
= 3 5/12 gallons
Step-by-step explanation:
Since it can hold 8 1/4 gallons and currently has 4 5/6 gallons, you subtract.
You need to get the common denominator to subtract cleanly so we can turn the fractions into improper fractions.
8 1/4 = 33/4 because 8 is equal to 8 full 4/4ths so multiply 8 by 4 and add 1 for the remaining 1/4.
Then 4 5/6 becomes 29/6 with the same concept earlier.
So we can change the denominator to 12 on both fractions (33/4 and 29/6) so we can subtract.
33/4 becomes 99/12 because they are still equivalent, it's just that you multiplied the top and bottom by the same number.
29/6 becomes 58/12 because we multiplied the fraction by 2/2.
Those two new fractions stated previously are the same as the original because we multiplied them by 1/1, because 3/3 and 2/2 is still equal to 1/1, and the new fractions can be simplified down to the original.
Since we have 99/12 and 58/12, we can subtract cleanly into
99 - 58 = 41
So the answer is 41/12
Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris' age is 66. How old is Beatrice?
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
