5. Andre makes green paint by mixing 5 cups of yellow paint with 2 cups of blue paint.
To make the same shade of green, how much yellow paint does Andre need if he uses 8 cups of blue paint?
How much blue paint does Andre need if he uses 15 cups of yellow paint?
Plot these pairs of measurements as points on the graph.
Answers
Answer:
for part 1, the answer is (8, 20), and part 2 is (6, 15)
Step-by-step explanation:
hope this helps you out! :)
Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To make green paint, Andre uses a ratio of 5 cups yellow paint to 2 cups blue paint.
To make the same shade of green using 8 cups of blue paint, we need to use the same ratio of yellow paint to blue paint as before.
So we can set up a proportion:
5/2 = x/8
where x is the amount of yellow paint Andre needs.
Solving for x, we get:
x = (5/2) x 8 = 20 cups
Andre needs 20 cups of yellow paint to make the same shade of green using 8 cups of blue paint.
To make the same shade of green using 15 cups of yellow paint, we can set up another proportion:
5/2 = 15/y
where y is the amount of blue paint Andre needs.
Solving for y, we get:
y = (2/5) x 15 = 6 cups
Therefore,
Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.

Step-by-step explanation:
16x = 73 - 27x is the equation in the first step.
David is correctly applying the addition property of equality in the first step of his work.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 8 is an equation.
We have,
16x - 38 = 35 - 27x
Add 38 on both sides.
16x = 35 + 38 - 27x
16x = 73 - 27x
Add 27x on both sides.
16x + 27x = 73
43x = 73
x = 73/43
Thus,
16x = 73 - 27x is the equation in the first step.

Equation #1: 3x + 11 = 11
Equation #2: 3(x - 3) = 45
Answers
Step-by-step explanation:
Given that,
Two equations,
3x + 11 = 11 .....(1)
And
3(x - 3) = 45
or
3x-9=45 ....(2)
Subtract 11 on both sides of equation (1).
3x + 11-11 = 11-11
3x=0
x = 0
Add 9 to both sides of equation (2)
3x-9+9=45+9
3x = 54
x = 18
Hence, the solution of equation (1) is x=0 and form equation (2) x = 18.
Solve: 40 + -58
Please help!
Answers
Answer:
-18
Step-by-step explanation:
because you take 40 + -58 and you can make the positive and negative sign a negative so now it would be 40-58
if you reverse it to make it 58-40 you would get 18 and then reverse it back to negative because you reversed it once so now its -18

Type SSS, SAS, ASA, SAA, or HL to
justify why the two larger triangles are
congruent.
Answers
Answer:
SAS
Step-by-step explanation:
It doesnt show the hypotenuse so its no HL
It doesnt show 2 angles so its not SAA or ASA
It doesnt show three sides so its not SSS
The little line indicates that the sides are congruent. They both have a right angle and the bottom lines are right on top of each other so its SAS
The theorem that justify why the two larger triangles are congruent is: SAS.
What is SAS?SAS means side-angle-side congruence theorem, which states that, two triangles are congruent if both have two pairs of congruent sides and a pair of congruent included angles.
Thus, the image shows two angles having:
two pairs of congruent sides - equal leg and a shared lega pair of congruent included angles - right angles.Therefore, the theorem that justify why the two larger triangles are congruent is: SAS.
