Boys to girls ratio is 3:4 so for every 7 students 3 are boys and 4 are girls bc 3+4 is total students in the ratio. boys are 3/7 so out of 28 students there are 12 boys and girls are 4/7 so out of 28 students 16 are girls
12/28 are boys
16/28 are girls

Ratio is 3:4
so total is 3+4=7 units
so we know the ratio for every 7 units
count hohw many 7 units there are
28/7=4
4 units
that means 4 times of each seperate unit
3 times 4=12
4 times 4=16
there are 12 boys and 16 girls

2 - 3d = 4d - 19<br><br>Answer and show steps​
defon

2 - 3d = 4d - 19

Add the opposite to both sides to get the variable on the left side only.

2 - 3d = 4d - 19

   -4d    -4d

2 - 7d = - 19

Then get the terms w/o variables on the right,

2 - 7d = - 19

-2            -2

-7d = -21

Then divide by the number paired with the variable.

--7d = -21

-----    -----   ;   d = 3

-7       -7

Final answer = 3

Hope I helped :)
