Answer:

m=20n

Step-by-step explanation:

Let

A(5,100),B(10,200)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

slope=\frac{m2-m1}{n2-n1}

substitute the values

slope=\frac{200-100}{10-5}=20

step 2

Find the equation of the line into slope-point

m-m1=slope(n-n1)

with the slope and the point A

m-100=20(n-5)

m=20n-100+100

m=20n

Find the value of x.
BartSMP [9]

Answer:

56

Step-by-step explanation:

We know that every triangle no matter will equal 180 degrees. So we will make an algebreic expression.

2x+8+60=180

When doing algebreic expression we want to simply as much as possible to find our answer. First we will do 60-180. Since the expression is adding 60 we want to do the opposite and subtract is by 60 on both sides. SO now we have 2x+8=120. We do the same thing with 8. Subtract it on  both sides since its adding in the expression. Now we have 2x=112. FInally, we will divide by two on both sides since its multiplying on the other side of the equation. So now we are left with x=56.

Plssssssssssssssssssssssssssssssssssssssssssssss
eduard

Answer:

34 hours

Step-by-step explanation:

Lets call M the number of hours that Maddie volunteered. Ryan volunteered 1 + 3×M hours, and altogether they volunteered 45 hours, so:

1 + 3×M + M = 45

1 + 4M = 45 Subtract 1 in both sides

4M = 44 Divide both sides by 4

M = 11 hours

So Maddie volunteered 11 hours, and Ryan volunteered

1 + 3×11 = 34 hours
