Answer:
n = 55/8
Step-by-step explanation:
You can solve it by cross multiplying. Where you multiply the denominator of the fraction on the left side with the numerator on the right side, and vice versa.
11/n = 8/5
n x 8 = 11 x 5
8n = 55
n = 55/8
(or 6.875)

Answer:
150
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.
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
24y=100(36)
24y=3600
y=150.
There are 150 students in the choir.
Answer:
<h2>y-7=(x-5)</h2>
Step-by-step explanation:
<h3>to understand the solving steps</h3><h3>you need to know about</h3>
- linear equation i.g point-slope
- PEMDAS
<h3>given:</h3>
- m=1
- (x1,y1)=(5,7)
<h3>let's solve:</h3>
point-slope form is y-y1=m(x-x1)
so the point-slope equation is
<h3>y-7=1(x-5)</h3><h2>=y-7=(x-5)</h2>
