Answer:
Total number of pupils who received the prize = 10
Step-by-step explanation:
Number of boys in the Math Quiz Competition = 40
Number of girls = 20
Percentage of girls who received the prize = 20%
Therefore, number of girls who received prize = 20% of 20
=
= 4
Percentage of boys who received the prize = 15%
Therefore, number of boys who received the prize =
= 6
Total number of pupils who received the prize = 4 + 6 = 10
7x - 81 = -2 + 72.
First you add up the left side. This gives us:
-2 + 72 = 70
So the equation becomes:
7× - 81 = 70
Now we add up 81 on both sides to get rid of the 81 on the left
7x = 151
Now divide both sides by 7
x = 151/7
I hope this clears it up for you! :)
