Answer:

Yes, It's correct.

Step-by-step explanation:

{ (\frac{3}{2} )}^{ - 5}  =  {( \frac{2}{3}) }^{5}  \\  \frac{1}{ {( \frac{3}{2} )}^{5} }  =  {( \frac{2}{3}) }^{5}  \\ 1 \div  { (\frac{3}{2}) }^{5}  =  {( \frac{2}{3} )}^{5}  \\1  \times  { (\frac{2}{3}) }^{5}  =  {( \frac{2}{3}) }^{5}  \\   {( \frac{2}{3} )}^{5}  = {( \frac{2}{3} )}^{5}  \\

Simplify the expression if possible by combining like terms 9(X+5)+7(X-3)
IceJOKER [234]
So you do
distribute
a(b+c)=ab+ac
9(x+5)=9x+9 times 5=9x+45

7(x-3)=7x+7 times -3=7x-21

so now we have
9x+45+7x-21
group like terms
9x+7x+45-21
add
16x+24

simplified is 16x+24

A garden table and bench cost $742, the table cost $92 more than the bench how much was the bench
Llana [10]

Answer:

The bench cost $325

Step-by-step explanation:

Garden Table + Bench = $742

g + b = $742

Garden Table - Bench = $92

g - b = $92

g = $92 + b

Substitute g into total cost equation

$92 + b + b = $742

$92 + 2b = $742

2b = $650

b = $325

The bench cost $325

Hope this helps :)
