The nonpermissible replacement is a value that make the denominator equal to zero
Answer:
66 girls
Step-by-step explanation:
Givens:
●120% boys of girls
▪︎1.2 × g
☆when g is the number of girls
●80 boys
▪︎meaning you can set up a proportion
Solving:
g × 1.2 = 80
g=80/1.2
g=66.66
So, since you can't go over percent, the answer is 66.
Checking:
g × 1.2 = 80
66 × 1.2 = 80
80=80✅

Answer: 79
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
10x² - 7x + 10
x = 3
<u>Substitute the value into the expression</u>
= 10 (3)² - 7 (3) + 10
<u>Simplify by multiplication</u>
= 10 (9) - 21 + 10
= 90 - 21 + 10
<u>Simplify by subtraction</u>
= 69 + 10
<u>Simplify by addition</u>
= 79
