I’m going to assume you meant “what is the value of x” and “line A is parallel to line B”

Because they are parallel, the equation and 80 degrees are the same, so:

2x+20=80

Now just solve for x

2x+20=80
-20 -20

2x=60
— —

X=30

What number can go into 2470,121 and 45<br>​
Usimov [2.4K]

Answer:

Step-by-step explanation:

All of these numbers can be divided by 2, 3, 5, 7, 11, 13...

There is no whole number if you want to divide each number.

121 only goes into 1, 11, and 121. No other numbers have 11

45/2 = 22.5

45/3 = 15

45/5 = 9

2470/2 = 1235

2470/3 = 823.33333...

2470/5 = 494

121/2 = 60.5

121/3 = 40.33333...

121/5 = 24.2

What is the solution to the inequality 0.8x+20&lt;1.2x−40?
LuckyWell [14K]

Answer:x=150

Step-by-step explanation:

Step 1: Subtract 1.2x from both sides.

0.8x+20−1.2x=1.2x−40−1.2x

−0.4x+20=−40

Step 2: Subtract 20 from both sides.

−0.4x+20−20=−40−20

−0.4x=−60

Step 3: Divide both sides by -0.4.

−0.4x

−0.4

=

−60

−0.4

shutvik [7]

Answer:

3

Step-by-step explanation:

Break the problem up into two

Ignore the -1 for now

2+2=4 because if you separate 2 and 2, you get four ones, therefore it's four

Now that you have four, subtract 1

And you got 3
