An ESTIMATE of 39% of 120
malfutka [58]

ANSWER: 46.8


39% of 120

The word "of" means multiplied. So you will have to multiply 39% x 120

To do that, first step is to change the percent (39%) into a decimal


39% = 0.39  (You move the decimal twice to the left, not right)

There's an invisible decimal behind 9 so ALWAYS move it twice.

= 39(.)⇒ 0.39


Then your final step is to multiply

120 x 0.39


    1 2 0

x 0 . 3 9   ← notice this decimal

_______                    ∨

 1 0 8 0                     ∨

+ 3 6 0 0                    ∨

_______                    ∨

  4 6 8 0          There's an invisible decimal before the 0. Move that decimal two times to                                  the left.   4680(.)⇒ 46.8

Whatis the answer to the problem
Stels [109]

Answer:

slope = -\frac{1}{8}

Step-by-step explanation:

Use the slope formula given in the question to solve for the slope. The m is the variable representing the slope. The x_1 and y_1 values are x and y values of one point. The x_2 and y_2  are x and y values of another point.

So, use the x and y values of the points given and substitute them in the correct order into the formula:

m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}

Thus, the slope is -\frac{1}{8}.
