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
Hope this makes sense
Answer:-7/4
2(x-2)=6x+2-2(-2x-4)
Open brackets
2x-4=6x+2+4x+8
Collect like terms
-4-2-8=6x+4x-2x
-14=8x
Divide both sides by 8
-14/8=8x/8
-7/4=x
x=-7/4
