Step-by-step explanation:
Variable x = total number of students enrolled
495 people at the dance - 7 teachers = 488 students
4/5 = 488/x
Step 1: cross multiply
4x = 2440
Step 2: isolate the variable (x) by dividing by 4
x = 2440 ÷ 4
Step 3: solve
x= 610 students total
Answer:
x²+4x+3
Step-by-step explanation:
(f+g)(x) = f(x) + g(x)
= (x²+3x+2) + (x+1)
= x²+4x+3
9/2
9 x 2 and 2 x 2 is equal to 18/4
9 x 3 and 2 x 3 is equal to 27/6
9 x 4 and 2 x 4 is equal to 36/8
I did the best I could to understand this problem. Do not quote me on this please.
Subtract 1/2x from 2/3x to get 3=1/6x +1. Subtract 1 from both sides then multiply both sides by 6 to get X=12
Answer:
area of the square = (SIDE)2
=( 4)^2
= 16 answer
