Please help me out i just need to know what x=
Answer:
7
Step-by-step explanation:
x +4+2x+1+3x-2 = perimeter of triangle.
(6x +3)ft = perimeter

At the country fair, Maya observes that the wheel of chance has 25 numbered slots. If each play costs a quarter, how much will Maya likely have to spend before she gets her winning number?
Answer:
6 1/4
Step-by-step explanation:
Given
Total number of wheel chance = 25
Each play = 1 quarter
1 play = 1/4
To calculate the amount Maya has to spend to get her winning number, we will say;
25 plays = x
Divide both expressions
1/25 = 1/4÷x
1/25 = 1/4x
Cross multiply
4x = 25
x = 25/4
x = 6 1/4
This mean that Maya will have to spend 6 1/4 before she gets her winning number
