Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7
Answer:
<u>6 bottles of soda.</u>
Step-by-step explanation:
lets keep the number of bottles as = x
Format :
(9/12)=(8/x)
Step 1: Cross-multiply.
(9)*(8)=(x)*(12)
72=12x
Step 2:Bring x one side.
12x=72
x=72/12=6bottles
Bottles of soda will be need to buy for a party where 8 people are attending=<u>6 bottles soda</u>

Answer: Weight of a person to a person's height</h3>
Let x = weight and y = height. It is possible to have a certain weight correspond to multiple heights. This means the input x has multiple output y values. Therefore, we cannot have a function here. A function is only possible if for any x input, there is exactly one y output. The x value must be in the domain.
