Answer:
79
Step-by-step explanation:
Let the original number be x.
x/2 = 39.5
x = 39.5 × 2
x = 79
9514 1404 393
Answer:
Step-by-step explanation:
The midline is half the length of the parallel base.
2(2x +36) = 3x +57
4x +72 = 3x +57 . . . . . . eliminate parentheses
x = -15 . . . . . . . . . . subtract 72+3x from both sides
Then the length of GH is ...
GH = 2x +36 = 2(-15) +36 = -30 +36
GH = 6
_____
The calculation steps are shown above. The strategy is to take advantage of the relation between the lengths of a midline and the corresponding base segment.
4x + 5832x = 5836x
If that's not correct put the exponents back which then this would be your answer
4x^2 + 5832x^3
Hope this helps, good luck my friend.
Gallon= 16 cups
Quart= 4 cups
Pint= 2 cups
1(16)+3(2)+1(4)+5=31 NOT 20
