Solve -5 < 2x+3 >= 7

Mathematics
1 answer:
Sergeu [11.5K]3 years ago
5 0

Answer:

Step-by-step explanation:

so just solve this as if it's

-5= 2x+3

and

2x+3 = 7 ( be careful not to switch sides or the arrow switches too)

the the top equation looks like

-8=2x

-8/2 = x

-4 =x

the bottom equation looks like

2x = 4

x = 4/2

x = 2

now put it back together with the arrows in the same direction :) ( we don't have to worry about switching directions of the arrows b/c we didn't switch side,  multiply or divide by a negative, so all good :P)

-4<x<=2

Each square below represents one whole.
tatiyna

Answer:

160%

Step-by-step explanation:

Because the first square (the one to the left) is shaded to the brim, it represents 100%.

The second square (the one to the right) is shaded only until the 6th row, we can say that it is shaded 6/10 rows, or 60%.

Lastly, add the percentages of the two squares => 100% + 60% = 160%

-19x+9 is the answer
First distribute -5 and -7 once you that you’ll get -5x+30 and -14x-21 so now you have -5x+30-14x-21 you then are gonna combine like terms so -5x-14x is -19x and 30-21 is 9 and so you’ve simplified all you can and end up with -19x+9
