You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.
3/4 = x / 236 Cross multiply
4x = 3 * 236
4x = 708 Divide by 4
x = 708/4
x = 177
There are 177 boys at the school and 236 - 177 = 59 girls.

Step-by-step explanation:
3 hours 1/4 times two equals 30 1/2 times 2 equals 1 hour 3/4 times 2 equals 90. 30 plus 60 plus 90 180. 180 divided by 60 is 3 so three hours.
Answer:
Step-by-step explanation:
we can do like
8y-7x+2y² -x-5
= 2y^2 + 8y - 8x - 5 ( we know that - 5 = 8 - 13)
= 2( y^2 + 4y + 4) - 8x - 13
= 2 (y+2)^2 -8x - 13
I do not know that you wrongly type but here is the answer.
