Answer:
The answer to this one is 0.25
Step-by-step explanation:
The ratio is 4:3
First you would do 4 + 3 which is 7
Then you would do 35 ÷ 7 which is 5
Finally we would multiply 5 to the ratio 4:3
So 7 × 4 is 28
And 7 × 3 is 21
So the new ratio is 28:21
So there are 21 girls in the class

Answer:
(x) = 
Step-by-step explanation:
let y = - 8x + 4
rearrange making x the subject
add 8x to both sides
8x + y = 4 ( subtract y from both sides )
8x = 4 - y ( divide both sides by 8 )
x = 
change y back into terms of x, then
(x) =
