Hey Miranda!

Let me help you out...

First, keep in mind that they just put these negative signs to make the thing looks difficult to solve :)

Do you remember this:
Minus * Minus = Plus 


Well this the same thing. We gonna multiply the two negative signs that are behind the parentheses together and make it plus sign

Here is how it works
8-[-(-3)]

=8 + (-3)

=8 - 3 

=5

The correct answer is option A (5)

Good luck with your studies, Miranda.

From a board 8 feet in length, Emmet cut two 2 ⅓ foot bookshelves. How much of the board remained?
RideAnS [48]

Answer:

3 2/5

I converted these into decimals, because I find it easier ^.^

We have an 8 feet board, and we twice remove 2 1/3 from that number.

8 - 2 1/3 = 5.7

5.7 - 2 1/3 = 3.4 or 3 2/5

~Hope this helps~

Solve for x and show work 10x + 80 < y = 20x​
julsineya [31]

Answer:

x=8

Step-by-step explanation:

10x + 80 < y = 20x

subtract 80 from both sides

10x = 20x - 80

subtract 20 from both sides

-10x = -80

divide both sides by -10

Needing help with this!
Sonbull [250]

assuming the scale is by 1,

a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4

b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1

c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
