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

Having trouble with this one can someone teach me how to find the slope in this question. Try to help me learn it aswell. Its in

ASHA 777 [7]

Hi there! The answer is -2.

We can find the slope of a formula by using the following formula:

$slope = \frac{change \: of \: y}{change \: of \: x} =\frac{y2 - y1}{x2 - x1}$
x2 and y2 don't mean squared, but the x and y coordinate of our second point.

First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

$slope = \frac{ - 5 - 3}{1 - - 3} = \frac{ - 8}{4} = - 2$

Therefore, the third answer is correct.
~ Hope this helps you!
