8/9 + 4/7=1 29/63 ESTIMATE:2
8/9 - 4/7=<span>20/63 ESTIMATE:0
</span>
Answer:
-3.56 i think .
Step-by-step explanation:
2/5 are girls, therefore 3/5 are boys
3/5 = 24
1/5 = 24 ÷ 3 = 8
2/5 = 8 x 2 = 16
Altogether = 16 + 24 = 40
24 - 1 6 = 8
There are 40 children altogether
There are 8 more boys than girls.
1:04pm pretty sure i think that’s right
<span>x(t-u) = 3t
dividing both sides by (t-u):
So.. </span><span><em>x = 3t/(t-u)</em></span>
