Answer:
1987.2
Step-by-step explanation:
We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the strength of students increased by 8% to 2160 then the original was 92%.
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
92(2160)=100(y)
198720=100y
y=1987.2
There are 1987.2 as the original strength of students.
If you calculate the problem correctly you should end up with:
(A)-(3)
Which equals:
= -3

Find the slope, m, of the line whose graph contains the points (1,2) and (2, 7). ... What does it mean if the slope, m, is negative in y = mx + b?
The answer is option D, 4 bracelets/per hour
Answer: x=17 (if that’s what you mean)
explanation: a straight line is 180 degrees, so we can minus 180-115 which will give you 65, and if you set the equation given equal to 65, you’ll get 17
