7 0

Answer:

r=0

Step-by-step explanation:

10r-5r=3r-8r

We move all terms to the left:

10r-5r-(3r-8r)=0

We add all the numbers together, and all the variables

10r-5r-(-5r)=0

We add all the numbers together, and all the variables

5r-(-5r)=0

We get rid of parentheses

5r+5r=0

We add all the numbers together, and all the variables

10r=0

r=0/10

r=0

How can I solve this equation 6+7x=55
lorasvet [3.4K]

You could solve it with these two steps:

             #1).  Subtract 6 from each side of the equation.
and then
             #2). Divide each side by 7.

If you'll do that, the solution will be right there on the paper in front of you.
It'll begin with "x =", and right after that will be the value of 'x'.

A set of data has the trend line modeled by the equation Y =1.5x + 11. What value of X corresponds to y =56?
erica [24]

Answer:

x = 30

Step-by-step explanation:

Plug in 56 in place of  y, then solve for x.

56 = 1.5x + 11

Subtract 11.

45 = 1.5x

Divide both sides by 1.5.

45/1.5 = x

30 = x

As a membership fee a health club charges a one time amount of $40 and charges $25 for each month. The total fee after m months
ICE Princess25 [194]
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months

10 + 7r = 45
7r = 35
r = 5
