70 times .9 is 63 so 90 minus 63 is27 so it was $27
The question is to find out how many times 1/4 is equal to 1 1/2
First lets convert the total:
1 1/2 = 2/2 + 1/2 = 3/2
now we need to find out a number that multiplied by 1/4 gives 3/2, that is an equation:
(1/4)x = 3/2
and solving for x:
x = (3/2)*4
x = 12/2
x = 6
therefore they will take 6 days to repave the whole street
No because 3 x 4 = 12 and 8 x 4 ≠ 24
The temperature at 10 pm is -3 degrees
