Division is the opposite of multiplication
Answer:
369/10
Step-by-step explanation:
10 1/4=41/4
3 3/5=18/5
----------------
(41/4)(18/5)=738/20
simplify
369/10
Given:
25.7 kwh of electricity per day.
must reduce 20%
25.7 kwh * 20% = 5.14 kwh * amount of electricity to be reduced.
25.7 kwh - 5.14 kwh = 20.56 kwh * net of reduced electricity
The homeowner will use 20.56 kwh after reduction of 20%.
They charge $30 per month as a base so that is y
They also charge $0.25 per text message, this is x
so $0.25x+$30y=$59.50
first subtract 30 from both sides to get x alone
$0.25x=$29.50
To find amount of text messages sent, we have to divide
$29.50/$.25
29.50/.25=118
This person sent 118 text messages
9/8
3/2 x 3/4 = 9/8
