Answers
Answer:
11. A) 12
12. D)11
Step-by-step explanation:
11. We substitute x with 12 in 3(x)-11.
3(12)-11=
36-11= 25
We substitute x with 12 for the second equation (x+13).
12+13=25
Both answers match so the answer for #11 is 12.
12.We substitute x with 11 in 4(x)-4.
4(11)-4=
44-4=40
We substitute x with 11 for the second equation (2(x)+18)
2(11)+18=
22+18=40
Both answers match so the answer for #12 is 11.

Answers
Step-by-step explanation:
10 + 5x = 10 + 5(15)
= 10 + 75
= 85°
4x - 10 = 4(15) - 10
= 60 - 10
= 50°
6x - 5 = 6(15) - 5
= 90 - 5
= 85°

7. The probabilities that a patient will have blood drawn 0,1,2, or 3 times in a visit are 6/15, 5/15, 3/15, and 1/15, respectively.
Answers
Answer:
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Step-by-step explanation:
From the data, to produce a probability distribution for the data :
X : number of times blood is drawn ;
P(x) : probability that blood is drawn at X times
Hence, the probability distribution table for the data Given goes thus :
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Probability that blood is drawn 0 times = 6/15
Probability that blood is drawn 1 time = 5/15
Probability that blood is drawn 2 times = 3/15
Probability that blood is drawn 3 times = 1/15
(6/15 + 5/15 + 3/15 + 1/15) = 1

8) Jalyn purchased three different sized drinks. The large was twice as much
as the medium drink. The MEGA drink was $10 more than the large. Jalyn
spent a total of $45 on drinks! Write and solve an equation to determine the
cost of the medium drink.
Answers
Answer:MARK ME AS BRAINLIEST
MEGA Drink = $10+2x
LARGE Drink = 2x
MEDIUM Drink = x
hence, we conclude that
($10+2x) + 2x + x = $45
$10+2x + 2x + x =$ 45
5x + $10 = $45
5x = $45-$10
5x = $35
x = 35÷5
x = 7
MEGA DRINK = (10+2X)
10+2×7
10+14

LARGE DRINK = 2X
2×7 = 14
MEDIUM DRINK = X

two numbers have ratio 12:5.their differnce is 49.find the two numbers .
Answers
Answer:
84 and 35
Step-by-step explanation:
12 - 5 = 7
12(7) = 84
5(7) = 35
Two numbers: 84 and 35
Step-by-step explanation:
Let the two numbers be x and y
Given:
Ratio of two numbers= 12:5
Difference between two numbers= 49
So, we need to find the difference between its ratio in order to get two numbers.
12 - 5 = 7
Thus, simply on multiplying the number so obtained after subtraction we will get:
12 * (7) = 84
5 * (7) = 35
Also, the difference is given which is 49
so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49
Therefore, the two numbers are 84 and 35.

Liu is making a rabbit pen. The graph shows where he plans to place it in his backyard. Each unit on the graph represents 1 foot.
1. What is the distance between points R and U? Explain how you found this distance.
2. Find the other three side lengths.
The length of the side between U and T is _______ feet.
The length of the side between T and S is _______ feet.
The length of the side between S and R is _______ feet.
3. The perimeter is the sum of the side lengths. What is the perimeter of the pen?
4. Does Liu have enough fence to make the pen? Why or why not?
Answers
Answer:
1. The distance between the points R and U is 4 feet
2. The length of the side between U and T is 3 feet
The length of the side between T and S is 4 feet
The length of the side between S and R is 3 feet
3.The perimeter of the pen is 14 feet
4. Yes
Liu has enough fence to make the Pen because he has more fence than the perimeter of the pen
Step-by-step explanation:
The 'x', and 'y' (x, y) coordinates of the points are;
R(5, 7), U(5, 3), S(8, 7), T(8, 3)
1. From the graph, the distance between the points R and U is given by the change in the values of the y-coordinate, given in feet, since the x-coordinate values are the same
Therefore, the distance between the points R and U = 7 ft. - 3 ft. = 4 ft.
2. Similarly, the length of the side between U and T is given by the change in the values of the x-coordinate, given in feet, since the y-coordinate values of U ant T are the same, as follows;
The length of the side between U and T = 8 ft. - 5 ft. = 3 ft.
Similarly the length of the side between T and S which have the same x-coordinate values is given as follows
The length of the side between T and S = 7 ft. - 3 ft. = 4 ft.
The length of the side between S and R which have the same y-coordinate values is given as follows;
The length of the side between S and R = 8ft. - 5ft. = 3ft.
3. The perimeter of the pen = Length R and U + Length U and T + Length T and S + Length S and R
∴ The perimeter of the pen = 4 ft. + 3 ft. + 4 ft. + 3 ft. = 14 ft.
4. The length of fencing Liu has = 16 feet (from internet source)
Therefore, the length of fence Liu has, 16 ft.is more than the length that make up the perimeter of the pen, 14 ft.
Therefore Liu has enough fence to make the Pen because the length of fence he has is more than the perimeter of the pen.

Plz help me Jen can jump rope 80 times in 60 seconds. If she jumps at a constant ratio of seconds to jumps, how many jumps can she make in 15 seconds?
Answers
Answer:
The answer is 4
Step-by-step explanation:
You just divide 80 by 15.
She can jump rope 20 times in 15 seconds
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that Jen can jump rope 80 times in 60 seconds.
We have to determine the number of jumps can she make in 15 seconds.
Let the number of jumps would be x she can make in 15 seconds
Since she jumps at a constant ratio of seconds to jumps
So according to proportionality,
⇒ 80/60 = x/15
⇒ x = 15(80/60)
⇒ x = 20
Hence, she can jump rope 20 times in 15 seconds.

Samantha went to a concession stand and bought three pretzels and four sodas and paid a total of $11.25 for them. Raza went to the same stand and bought five pretzels and two sodas and paid a total of $8.25.
(a) Could pretzels have cost \$1.75 each and sodas $1.50 each ? How can you evaluate based on the information given ?
(b) Letting x equal the unit cost of a pretzel and letting y equal the unit cost of a soda, write a system of equations that models the information given .
(c) Solve the system of equations using the elimination method or a matrix,
(d) Leah went to the same concession stand and bought two sodas, how many pretzels would she need to buy so that she spent the same amount on both
Answers
Answer:
No, because their respective prices are $0.75 and $2.25
Step-by-step explanation:
Let's assume that the price of each pretzel is x and the price of each soda is y
3x + 4y = 11.25_____ equation 1
5x + 2y = 8.25_____ equation 2
Multiply equation 2 by the figure 2 so as to have both equation sharing the same coefficient of y
10x + 4y = 16.5____ equation 1
3x + 4y = 11.25____ equation 2
Now subtract equation 2 from 1
7x = 5.25
X = 5.25/7
X = 0.75
Now substitute x = 0.75 in equation 1
10x + 4y = 16.5
10(0.75) + 4y = 16.5
7.5 + 4y = 16.5
4y = 16.5 - 7.5
4y = 9
Y = 2.25
Therefore,the cost of each pretzel is $0.75 while that of soda is $2.25
