Step-by-step explanation:
<span>3y + 53 = 7y - 55 is a three step equation. Our goal is to get 'y' by itself.
First we subtract 3y on both sides of the equation.
</span>3y + 53 = 7y - 55
-3y -3y
53 = 4y - 55
Then we add 55 on both sides of the equation.
53 = 4y - 55
+55 +55
108 = 4y
Finally we divide 4 on both sides.
108 = 4y

27 = y is the answer
Answer:
Of the basketball players on the team, exactly 75% of the players have heights above 180
Step-by-step explanation:
So, they are 12 basketball players in total
1 - 170 - This is 1/12
2 - 175 - This is 1/6
1 - 180 - This is 1/12
4- 185 - This is 1/3
3 - 190 - This is 1/4
1 - 195 - This is 1/12
75% (Or 3/4) have heights above 180
Therefore, the answer is B
The ratio is 4:5 meaning out of 9 students 4 are girls and 5 are boys. If there are 36 students, 9 will go into 36 four times so if we multiply each number of the ratio by 4 it gives us the answer.
4:5
4x4 = 16
5x4 = 20
The ratio is 16:20
16 girls to 20 boys... 16 +20 = 36
