Yo im not good at this stuff, can someone help me?​
Kazeer [188]

Answer:

  21 kWh

Step-by-step explanation:

1. Subtract 25% from the original amount.

  25% of 28 kWh is ...

  0.25 × 28 kWh = 7.00 kWh

Subtracting this from 28 kWh, we find the usage after reduction to be ...

  28 kWh - 7 kWh = 21 kWh

__

2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...

  (3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh

__

Mario must reduce his usage to 21 kWh or less.

Can someone please help me with all 3 of these questions <br> By today thank you

5 x 2/4 = 5/1 x 2/4 =  2 2/4 = 2 1/2
<span>8)  </span> not equal, not equal, equal
9)   1/8 of a pound is in each portion
10)   $3.75

I hope this helps you. With number 8, all i did was simplify the fractions and see if the can be equal to the first fraction in the whole question and determined my answer by that. For number 9, i divided 1/2 of a pound by 2 and got 1/4 of a pound, and then divided that by 2, and i got the answer of 1/8 of a pound. When it come to number 10, i multiplied $0.50 by 7 and got $3.50, and since the last part was half a foot i knew it would cost $0.25 instead of $0.50, so i just added that to the answer and got the end result of $3.75.
