It costs $5.08 for 4 pounds of gummy candy in bulk. How much would it cost to buy 17 pounds?
Daniel [21]

Answer:

$21.59

Step-by-step explanation:

Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.

what is the slope of the line through (1,0)(1,0)left parenthesis, 1, comma, 0, right parenthesis and (3,8)(3,8)
77julia77 [94]

The slope of the line passing through (1 , 0) and (3 , 8) is 4.

Slope, commonly represented by the letter m, is a value that describes the steepness and direction of a line. The slope of a line is also called its gradient or rate of change.

It is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, (x_{1}, y_{1} ) and (x_{2}, y_{2} ), to calculate the change in y over the change in x.

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} }     where

x_{1} = 1

y_{1} = 0

x_{2} = 3

y_{2} = 8

Substituting the values,

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} } =\frac{8-0}{3-1} =\frac{8}{2}=4

Hence, he slope of the line passing through (1 , 0) and (3 , 8) is 4.

Find the measure of ∠2.<br><br> and how did you find the answer??
Rufina [12.5K]
The 2 lines are parallel, so the 2 sides(e.g. 1 and 2/ 3 and 49) add up = 180 and In this case the 2 sides are equal as u can see from the original diagram so the angle  of 2 is 180-49=131.

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7
NeX [460]

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol
