The answer should be 2.12
Step-by-step explanation:
let the number of questions solved by Andy=x
this implies that 6+x=10
making x the subject of the equation
x=10-6
x=4
therefore Andy solved 4 questions
To get the answer, you have to isolate x. The first step to do so is to get the x's together, and the rest on the other side. You add 2 to both sides to get rid of the -2 on the left side, and add x to both sides to get rid of the -x on the right side so you have:
6x=-18
Your final step to isolating x is to divide both sides by 6 so you get:
x=-3
I wish I could help you but Im doing this so i can ask sum
Volume of cube formula is V = a^3
a^3 = 125
a = 5
(5 x 5 x 5 = 125)
