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:
Solution given:
x²-36
x²-6²
(x+6)(x-6)
is your answer
2.52.
If one number is x then the other = 3x/8.
Also x - 3x / 8 = 4.2
x - 0.375 x = 4.2
0.625x = 4.2
x = 4.2 / 0.625
x = 6.72.
So the lesser number is 6.72 * 0.375 = 2.52.
