A = 153
Answer:
x = 8
Step-by-step explanation:
7x + 2(6x + 9) = 170
2(6x + 9) = 12x + 18
7x + 12x + 18 = 170
19x = 152
152/19 = 8
x = 8
Answer:
The answer would be 135
Step-by-step explanation:
This would be the answer because if you have 300 students, you would divide the total amout of students surveyed, which, in this case would be 7.5.Next, what you would do is take the total amout of students who said chocolate chip ice cream was their favorite and multiply 18 x 7.5 which is 135.
Therefore, the correct answer would be : 135 students out of 300 would be an estimate of how many would say chocolate chip ice cream is their favorite.
