slamgirl [31]

Answer:

You show them in pictures.

This is 2/3.



This is 3/5.



They’re pretty similar, but you can tell that more is shaded in the first than the second. If they’re 8 though, then they’re probably in 2nd or 3rd grade. They’ll get it.

Solve 7+x÷3=2x-5 pls help me with this
bezimeni [28]

Answer:

4.4

Step-by-step explanation:

Write the question out as an equation:

7+x/3 = 2x - 5

Rearrange , simplify and solve:

7+x = 3(2x-5) = 6x - 15

7+x = 6x-15

6x - 15 = 7+x

6x = 7+x+15 = 22+x

6x = 22+x

6x-x = 22

5x = 22

x = 4.4

hope this helps.

Good Luck.
