63-3(2-10x) = 150
63-6+30x = 150
*57+30x = 150*
30x = 150 -57
30x = 93
x = 31/10

The answer is...D. It appears in the third step of my work. :)

Answer:

$\frac{7}{11}$

Step-by-step explanation:

We require 2 equations with the repeating digits (63) placed after the decimal point.

let x = 0.636363..... (1) multiply both sides by 100

100x = 63.6363... (2)

Subtract (1) from (2) thus eliminating the repeating digits

99x = 63 ( divide both sides by 99 )

x = $\frac{63}{99}$ = $\frac{7}{11}$ ← in simplest form

Please help I’m really struggling with this

Answer:

$y=\frac{1}{3} x+4$

Step-by-step explanation:

A linear equation is written as $y=mx+b$ , "m" being the slope and "b" being the y-intercept.

The slope is how many times you rise/run in order to get from one point on the line to the next. You rise (go up/down) 1 unit and run (go left/right) 3 units. Plug in the numbers and you get 1/3.

The y-intercept is where the graph lands on the y-axis, which is 4.

The problem here is: Too many words.

If you boil the problem down to the bare facts, the question is:

   "$210 is 15% of what number ?"

I'm pretty sure you can take it from there,
but here's the rest of it anyway:

$210 = 15% of (March amount)

      $210 = 0.15 x (March amount)

Divide each side by 0.15 :   $1400 = March amount .

Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!
