Divide the numerator and the denominator of the given rate by the denominator of the given rate. so in this case, divide the numerator and denominator of 70/5 by 5 to get 14/1 or 14 students per class
Answer:
55
Step-by-step explanation:
The total is 2(2x+15) +2x=360.
4x+30+2x=360
6x+30=360
6x=330
x=55
-2(y = x - 2) -----> -2y = -2x + 4
y = 2x + 4 --------> + y = 2x + 4
-1y = 8
/ -1 /-1
y = -8
y = x -2
-8 = x -2
+ 2 +2
-6 = x
The answer is ( -6, -8)
Answer:
54
Step-by-step explanation:
First add like terms: 5x+90=360
Then subtract 90 from both sides: 5x=270
Then divide both sides by 5: x=54
