X=number of students at Marita's high school last year
98%=.98
.98x=1170
x=1170/.98
x=1194
What does that mean that’s not a real question is it
7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===
Answer:
15.
Step-by-step explanation:
450 / 2 = 225.
225= 3 * 3 * 5 * 5
So √225 = 3 * 5 = 15.
In solving algebraic expressions, there is an order in which to solve it.
1) perform the operation inside the parenthesis first
2) then perform the operation with the exponents
3) apply multiplication and division from left to right of the equation.
4) apply addition and subtraction from left to right of the equation.
Remember this: PEMDAS for easier recall. (parenthesis, exponents, multiplication, division, addition, subtraction)
