Answer:

divide 1400 by 210

then multiply by 18

subtract that answer (120) from 1400,

and you get 1280

What is the solution to the equation <br> 13×3/4+x=7(1/4)
yan [13]
I'm going to assume you mean:

13 * (3/4) + x = 7 * (1/4)

Let's go ahead and simplify the right side.

7 * (1/4) = 1.75

So now we have:


13 * (3/4) + x = 1.75

Now let's take care of the right side. Multiplication before addition.

13 * (3/4) = 9.75

9.75 + x = 1.75

To isolate x, we subtract 9.75 from both sides.

9.75 - 9.75 + x = 1.75 - 9.75

x = -8

Hopefully I spaced this well. \('-')/

PLSSS HELPPP DUE SOON ILL GIVE BRAINLESS
Kitty [74]

Answer:

D

Step-by-step explanation:

A, B, and C are not linear functions

D would be y=x/2

If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)

It's more obvious if you notice that y is half of x.
