For the cylinder on the left-hand-side,

now, for the triangular prism on the right-hand-side,
notice is really just 2 triangles and 3 rectangles, stacked up to each other at the edges.
the triangles have a base of 4, and a height of 1.5.
the rectangle on the left and the one on the right is a 6x2.5 rectangle.
the rectangle at the bottom, is a 4x6 rectangle.
adding their areas, is the area of the prism,
Divide 50 and 20 and you get 2.5 then multiply that with 8 and you’ll get 20
THE ANSWER IS 20
Answer:
x - y is also a rational number. Hence satisfies the closure property.
Step-by-step explanation:

Closure property of subtraction states that for any two integers a and b, (a - b) must also be an integer.
Here x and y are rational numbers. so x - y must also be rational to satisfy the closure property.

We know that
scale =measure in the map/measure in the actual
measure in the actual=measure in the map/scale
scale=1 cm/ 80 mi
for
measure in the map=7.5 cm
measure in the actual=?
measure in the actual=7.5 /(1/80)-----> 7.5*80-----> 600 mi
the answer is
<span>the actual distance between the two cities is 600 miles</span>
Y =

Multilpy both sides by b
yb = x - v Add v to both sides
yb + v = x Switch the sides to make it easier to read
x = yb + v
