Answer:
Write an equation that will model the proportional relationship given in each real world situation.
1. There are 3 cans that store 9 tennis balls. Consider the number of balls per can.
a. Find the constant of proportionality for this situation.
9 balls (B)
_________ = 3
3 cans (C)
b. Write an equation to represent the relationship.
b = 3c
Answer:
3x + 12
Step-by-step explanation:
Use the distributive property.
3(x + 4) = 3 * x + 3 * 4 = 3x + 12
Answer: 3x + 12
C. 7 hours because to find the hourly pay do 21 divided by 3 which is equal to 7
Complement adds to 90
complement of A is 90-A
supplement is adds to 180
supplemetn of A is 180-A
2(90-A) is -40+180-A
2(90-A)=-40+180-A
2(90-A)=140-A
distribute
180-2A=140-A
add 2A to both sides
180=140+A
minus 140 both sides
40=A
A=40 degres
