Answer:
60
Step-by-step explanation:
750÷12.5=60
Convert 12 and a half hours into a decimal.=12.5
You would divide the 750 by the 12.5.
Answer:
The constant of proportionality is 5/3
Step-by-step explanation:
3 * k = 5
k = 5/3
Check
9 * k = 15
9 * 5/3 = 15
3*5 = 15
15 =15
The constant of proportionality is 5/3
So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you <span>−2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on
but at the end you should get x=-1 and y =3

917 - 67 = 850 (subtract the difference)
850 / 2 = 425 (divide the cost of the washer/dryer)
425 + 67 = 492 (add the difference)
The dryer costs $492.
