Answer:
$36.69
Step-by-step explanation:
Okay, so let's first write the equation:
2.59*10 + 3d = 135.97
Now, let's work on isolating d by first simplifying the equation:
25.9 + 3d = 135.97
25.9 + 3d - 25.9 = 135.97 - 25.9
3d = 110.07
3d/3 = 110.07/3
d = 36.69
Okay, now let's check:
2.59*10 + 3*36.69 = 135.97
25.9 + 110.07 = 135.97
135.97 = 135.97
Okay, so so it costs $36.69 per pair of shoe.
1st: Expand the bracket
3t-3=9+t
2nd: Add the 3 to get rid of it on the first side. Do this to both sides
3t=12+t
3rd: Take away the t on the left hand side and one on the right hand side to just be left with t's on one side and integers on the other side
2t=12
4th: Divide both sides by 2 to find 1t
t=6
Hope this helps!! :)
Answer:
Step-by-step explanation:
1 cubic foot is 12 * 12 * 12 cubic inches.
1 cubic foot = 1728 cubic inches.
1 cubic foot = 1728 cubic inches
x cubic feet = 3456 Cross multiply
1728 x = 3456 * 1 Divide by 1728
x = 3456/1728
x = 2 cubic feet.
The other way to do this is
3456 cu inches [1 cubic Foot/1728 cubic inches] note that the units cancel and you are left with 1 division problem.
The question still comes to 2.
