42.5p=c
You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.
M is representing the amount of money each person paid
(M)10=425
M=425/10
M=42.50 <- since it’s about money
Each person paid $42.50
The cost for 15 people is $637.50.
42.5p=c
42.5(15)=637.5
Answer:
The expression to determine the total cost in dollars is 
.
Step-by-step explanation:
Given:
Service charge to make a photo book = $20
Cost per extra page = $0.75
Cost to ship the complete photo book = $5
We need to write expression to determine the total cost in dollars.
Solution:
Let the number of extra pages be denoted by 'x'.
Also Let the Total cost be denoted by 'y'.
Now we can say that;
Total cost will be equal to sum of Service charge to make a photo book and Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.
framing in equation form we get;
Hence the expression to determine the total cost in dollars is .
Answer:
x=8y/3-4
Step-by-step explanation:
What we have to do to solve for X into re arrange the equation so that X is by itself on one side of the equation. To start we will divide both sides by 3/8 to move it away from the X side and we get
8y/3=x+4 then we will subtract both sides by 4 to get x all by itself
8y/3-4=x

Sqrt18 = 3 sqrt2
sqrt 8 = 2 sqrt2
sqrt18 / sqrt 8 = 3 sqrt2 / 2 sqrt2 = 3/2 answer
Step-by-step explanation:
The formula is Distance=√(x2-x1)²+(y2 -y1)²
x1 is 5, x2 is 1, y1 is 9, y2 is 6
D = √( 1-5)² +(6-9)²
D = √(-4)²+(-3)²
D = √16+9
D = √25
D = 5 units
