Steps on how to Solve 7 - 2p > -5

ale4655 [162]

Hello!

Answer:

p<6

*The answer must have a positive sign and less than symbol sign.

Step-by-step explanation:

First, you subtract by 7 from both sides of an equation.

$7-2p-7>-5-7$

Then, simplify.

$-2p>-12$

Next, multiply by -1 from both sides of an equation.

$(-2p)(-1)$

Simplify.

$2p$

You can also divide by 2 from both sides of an equation.

$\frac{2p}{2}$

And finally, simplify and solve. You can also divide by the numbers.

$12/2=6$

Final answer: $p$

Hope this helps!

Thanks!

Have a great day!

katen-ka-za [31]

Answer:

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

Step-by-step explanation:

Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.

Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78

Cost of electricity = $0.18

Now in the case of electricity,

spending on Brand A = 635 $\times$ 0.18 = $114.3

spending on Brand B = 582 $\times$ 0.18 = $104.76

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54
