First, we can do distributive property.

-3(n + 8) = 15

-3 x n = -3n, -3 x 8 = -24 

So we have, -3n + -24 = 15
 
Minus -24 on both sides of the equal sign.

-3n + -24 - -24 = 15 - -24 

-3n = 39

Divide 3 on both sides.

-3n/-3 = 39/-3

n = -13

Hope i helped!! :D

-3(n + 8) = 15
-3n - 24 = 15
-3n = 15 + 24
-3n = 39
n = 39/-3
n = -13

What is the equivalent fraction? Drag the answer into the box to match the decimal. 0.7¯ ​799​​79​​70100​​711​
Vesna [10]
The equivalent fraction for 0.7 is 70/100.
 
You know this because 0.7 is the same as 7/10.

7/10 is the same as 70/100 when we create 7 groups of 10 (numerator) and 10 groups of 10 (denominator).

Also, placing a zero to the right of any number on the right hand side of the decimal point will not change the value.

0.70 is 70/100
