Answer:
about $2,557
Actual cost : $2556.97
Step-by-step explanation:
well since all of them are .99 if you round to the hundreths it make another dollar cause it will force the .9 to become 1.0
so it be 1450 for the refrigerator, 490 for the dishwasher, and 617 for the electric range.
add those numbers to get about $2,557
Hello!
lets solve your equation step by step, and with multiple solutions.
the first way to solve it is by simply adding the hours and the minutes together, then combine them.
8+3=11
12+15=27
you get 11 hours & 27 minutes
_____________________________________________________________
for the second one, we will be using minutes only, and there are 60 minutes in an hour
the second way to solve it is:
8*60=480
3*60=180
480+12+180+15=687
I hope this helps, and have a nice day.
15=0.5x+7
0.5x=12
X=24
His weekly allowance is $24
A * b = 30
a - b = 1
a + b = 11
take ur last 2 equations, and add them
a - b = 1
a + b = 11
--------------add
2a = 12
a = 12/2
a = 6
now its just a matter of subbing
a + b = 11
6 + b = 11
b = 11 - 6
b = 5
so a = 6 and b = 5...whose product is 30, whose difference is 1, and whose sum is 11.
Answer:
Step-by-step explanation:
We have been given that the area of a square is given by , where x is the length of one side.
Mary's original garden was in the shape of a square. She has decided to double the area of her garden. So the new area of Mary's garden will be 2 times the area of original garden.
We can represent this information in an equation as:
Therefore, the expression will represent the area of Mary's new garden.
To evaluate the area of new garden, if the side length of Mary's original garden was 8 feet, we will substitute x equals 8 in our expression.
Therefore, the area of Mary's new garden will be 128 square feet.
