Answer:

Step-by-step explanation:

Combine like terms

6) -4f - 9 -f + 15 =<u> -4f - f</u>  <u>-9  +15</u>

                          = -5f  + 6

7) 1.5g - 10 + 6.5g - 3 = <u>1.5g + 6.5g</u>   <u>- 10 - 3</u>

                                  = 8.0g -13

                                   = 8g - 13

8)

\frac{1}{2}h + 2h + \frac{3}{2}h - 1 = \frac{1}{2}h+\frac{3}{2}h+2h - 1\\

                           = \frac{1+3}{2}h + 2h -1\\\\= \frac{4}{2}h + 2h -1\\\\= 2h + 2h -1 \\\\= 4h - 1

9) 4.2j + 6.7j - 5j - 5 = 10.9j - 5j - 5

                                = 5.9j - 5

What percent of 130 is 52
zheka24 [161]
To find percentages, simply take the number that is not the "100%" number and divide it by the other number. 

in this case, 

52 / 130

complicated way of figuring it out if it makes more sense for you, 

find how much is 1% of 130

130/100= 1.3

1% of 130 = 1.3 

and then you just take 52 / 1.3

feel free to comment any questions on how to figure out future problems
