Answer:
x=-5.143 or
Step-by-step explanation:
Subtract 75 from 3 and you get -72
-72=4x
x=-5.143
3*25=75
so the question is 75/8
you would 10 packages since
8*8=64
8*9=72
but 8*10=80 is enough, remainder 5
Answer:
The sides of the triangle are 7 feet, 22 feet, and 24 feet respectively.
Step-by-step explanation:
Given that the perimeter of a triangle is 53 feet, and one side of the triangle is 15 feet shorter than the second side, while the third side is 2 feet longer than the second side, to find the length of each side, the following calculation:
53 = X - 15 + X + X + 2
53 + 15 - 2 = 3X
66 = 3X
66/3 = X
22 = X
22 - 15 = 7
22 + 2 = 24
22 + 24 + 7 = 53
Thus, the sides of the triangle are 7 feet, 22 feet, and 24 feet respectively.

778 mile x ? hours = 50 miles per hours
Therefore,
778 miles /50 mph = 15.56 hours
15.56 hours to the nearest tenth is 15.6 hours
15.56 hours = (15.56 x 60) 933.6 minutes
933.6 minutes to the nearest minute is 934 minutes
