If 15% of 4x is 20 less than x, what is the value of x?

Mathematics
1 answer:
Bess [88]2 years ago
4 0

The sentence "15% of 4x is 20 less than x"

translates to    0.15 • (4x)  = x – 20

Solving that…

    0.15(4x) = x - 20           multiplipy 0.15•4

          0.6x = x - 20           subtract x from both sides

         -0.4x = - 20              divide both sides by -0.4

                x = 50

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y−x=−12
rodikova [14]

First isolate the "y" in the equation.

2y - x = -12 Add x on both sides

2y - x + x = -12 + x

2y = -12 + x   Divide 2 on both sides to get "y" by itself

y = \frac{-12 +x}{2}

y = -6 + \frac{x}{2}

Your slope is \frac{1}{2}.

For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also \frac{1}{2}

y = mx + b

y = \frac{1}{2}x + b

To find "b", you plug in the point (18,2) into the equation

y = \frac{1}{2}x + b

2 = \frac{1}{2}(18) + b

2 = 9 + b Subtract 9 on both sides

2 - 9 = 9 - 9 + b

-7 = b


Your equation is:

y =\frac{1}{2}x - 7
