Answer:
3
Step-by-step explanation:
The equation for the area of a triangle is A=1/2(b)(h)
we have the area and the base, so we plug those values in resulting in 7 7/8=1/2(5 1/4)(h)
From there, we solve. Multiply 5 1/4 by 0.5, resulting in 2.625
then, you divide 7 7/8 by 2.625 and you get 3.
(-1/2)/x = -7/3
*multiply both sides by x
(-1/2) = (-7/3)x
*divide both sides by (-7/3)
(-1/2)/(-7/3) = x
dividing by a fraction is the same as multiplying by it's reciprocal:
x = (-1/2)*(-3/7)
* the negative signs cancel
x = (1/2)*(3/7)
x = (1*3)/(2*7)
<u><em>x = 3/14</em></u>
False because the shape may change but a circo could have the same volume as a ball. a box could have the same volume as a cylinder box
