Answer:
8.33333333333
Step-by-step explanation:
Solution for 3x-7=18 equation:
3x - 7 = 18
3x = 18 + 7
3x = 25 (divide both sides by 3 to get x)
3x/3 = 25/3
x = 8.33333333333
1/2 in. = 5 ft
so., 1 in. = 5 * 2 = 10 ft
Now, 2 in = 10 * 2 = 20 ft
In short, Your Answer would be Option D
Hope this helps!
Answer:
the first one
Step-by-step explanation:
ive done this before
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
I think the answer is 4y=-1 y=-1/4
