In this question, you're trying to make an equivalent expression.
Your expression should be similar to:
15g + 20h
One of the best ways to make an equivalent expression is by using the distributive property.
You would see they're both divisible by 5, so we would be using 5 in our expression.
Your expression should look like this:
5(3g + 4h)
Answer:
5(3g + 4h)
Answer:
B. 15"
Step-by-step explanation:

The tax rounded to the nearest penny would be $2.19 because you would round the 5 up.
Hello from MrBillDoesMath!
Answer: x^2 - 6.5x + 10.5 = 0
Discussion:
If the roots are 3 and 3.5, then the quadratic equation is
(x -3 ) ( x - 3.5) = 0
or
x * (x - 3.5) - 3 (x - 3.5) = 0
or
X^2 - 3.5X - 3X + 3(3.5) = 0
or
x^2 - 6.5x + 10.5 = 0
Thank you,

Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
