15h + 80 = 140

If you wanted to solve how many hours he worked:
15h + 80 = 140
15h = 60
h = 4.

Baldo's total earnings is the sum of his basic wage, $80, and the earnings he got from his overtime for h hours. This total should be equal to $140. The equation that represent this is,
                                   80 + 15h = 140
The value of h from this equation is 4.

Can someone please explain to me how to find the value of m? thanks<br>-10 = -10 + 7m
GarryVolchara [31]
                                        -10  =  -10  +  7m

Add  10  to each side:      0  =          7m

Divide each side by  7 :    0  =          m


Please take a second and just LOOK at the equation you started with.
It says: 

--  You have this number '-10' . 

--  Your number  -10  is going to be exactly the same size
     after you add 7 of something to it.

The ONLY way that could happen is if the 'something' is 'nothing' .

       ' m '  must be nothing.

What is the equation of a line that passes through the point (8, 1) and is perpendicular to the line whose equation is y=−2/3x+5
Anuta_ua [19.1K]

Answer:

y = \frac{3}{2} x-11

Step-by-step explanation:

We are to find the equation a line that passes through the point (8, 1) and which is perpendicular to a line whose equation isy = - \frac{2}{3} x+5.

We know that the slope of line which is perpendicular to another line is the negative reciprocal of the slope of the other line so it will be \frac{3}{2}.

Then, we will find the y-intercept of the line using the standard equation of a line:

y=mx+c

1=\frac{3}{2} (8)+c

c=-11

Therefore, the equation of the line will be y = \frac{3}{2} x-11.
