The system of linear equations represents the situation is;
x + y = 125
x + y = 1255x + 8y = 775
<h3>Simultaneous equation</h3>
Simultaneous equation is an equation in two unknown values are being solved for at the same time.
let
- number of quick washes = x
- number of premium washes = y
x + y = 125
5x + 8y = 775
From equation (1)
x = 125 - y
5x + 8y = 775
5(125 - y) + 8y = 775
625 - 5y + 8y = 775
- 5y + 8y = 775 - 625
3y = 150
y = 150/3
y = 50
x + y = 125
x + 50 = 125
x = 125 - 50
x = 75
Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.

Answer:
56 sq cm
Step-by-step explanation:
SA = Area of Base + 1/2·(Perimeter of Base)·(Slant height)
= 4² + 1/2(4x4)(5)
= 16 + 1/2(16)(5)
= 16 + 40
= 56
Answer:
2 and 6
Step-by-step explanation:
Fractions can't be added or subtracted if they don't have the same denominator. It doesn't have to be the least one, but they both have to be the same one. ... I can't think of a reason "why" that's short enough to type on an Android keyboard, but I'll give you this to think about: If I asked you to add 1/2. and. 1/5, and you didn't want to bother finding a common denominator, then what WOULD you use for a denominator for the sum ? ?
