£87.00
Emily's dad pays 3 parts of the meal
Divide £52.20 by 3 to find one part of the ratio
= £17.40 ← 1 part of the ratio
2 parts = 2 × £17.40 = £34.80 ← Emily's share
total cost = £52.20 + £34.80 = £87.00
-x^2+7x+12
Let’s use distributive property
6(x+2)-x(x-1)
6x+12
Now the other part of the expression
-x(x-1)
-x^2+x
Put both parts of the expression together
6x+12 -x^2+x
-x^2+7x+12
Hope this helps
Answer:
The number of car they did quick wash is 75 and the number of car they did premium washes is 50 .
Step-by-step explanation:
The number of cars they washed is equals to 125 cars. They made a total of $775 from the wash. The wash is in two category the quick washes which is $5 and the premium washes which is $8.
Let
number of car for quick washes = x
number of car for premium washes = y
Base on the equation given below
x + y =125 .........(i)
5x + 8y = 775 .......(ii)
Let us find x and y
from equation (i)
y = 125 - x
inserting the value of y in equation (ii)
5x + 8(125 - x) = 775
5x + 1000 - 8x = 775
-3x = -225
divide both sides by -3
x = -225/-3
x = 75
insert the value of x in equation (i)
75 + y =125
y = 125 -75
y = 50
The number of car they did quick wash is 75 and the number of car they did premium washes is 50 .
