That blank is a plus sign

ok so rememmber  you can do anythiing to an equation as long as you do it to both sides

-0.3x+2=0.4x-0.1
add 0.3x to both sides
2=0.7x-0.1
add 0.1 to both sides
2.1=0.7x
times 7 both sides
21=7x
divide both sides by 7
3=x

Can y’all plz help me ?
crimeas [40]

Answer:

x=-5

Step-by-step explanation

The first box has eight x's and six 1's which means that it would be written as 8x+6

The second box has four x's and fourteen -1's which means that it would be written as 4x-14

You set them equal to one another

8x+6=4x-14

You subtract 4x from both sides

4x+6=-14

Subtract 6 on both sides

4x=-20

Divide 4 on both sides

x=-5

Hope it helps :))

If you double a number and then add 16, you get 2/5 of the original number. What is the original number?
Flauer [41]

Let the number = x

A.T.Q,

2x+16 = 2x/5

5(2x+16) = 2x

10x+80 = 2x

8x = -80

x= -10

If numbers go on does that mean there rational ?

technically, yes because there is a mathematic formula behind numbers going on as long as it is a repeated pattern throughout the new numbers
