Explain how to isolate the variable in the equation -2/3n + 7 = 15
vodka [1.7K]

Answer:

n = -12

Step-by-step explanation:

(-2/3)n + 7 = 15          

(-2/3)n+7-7 = 15-7               Subtract by 7 on both sides

(-2/3)n = 8                         Multiply by the reciprocal of the fraction, which is                                                                                                  

(-2/3)n*(-3/2) = 8(-3/2)      This makes it so you get n *1 and isolates n.

n = -24/2 = -12

Find FH <br> Need help ASAP !!
otez555 [7]

Answer:

FH=22

Step-by-step explanation:

FH is the combined lengths of FG and GH.

In an equation, this is:

FH=FG+GH

We already know that FG is 8 and that GH is 14. Thus:

FH=8+14

Add:

FH=22

So, the length of FH is 22.

And we're done!

if the volume of a triangular prism is 140 cubed the base length is 5 and base height is 8 what is the height
Arte-miy333 [17]
The height would be 7cm because the area of the base (the triangle face) is 20cm². You would then divide the volume by the area of the base to get the height. 140/20=7cm
Hope this helped!
