Answer:


Step-by-step explanation:

L=3S

In 5 years,

L+5=2(S+5)

L+5=2S+10

L=2S+5

 Substituting from above,

3S=2S+5

S=5

So then,

L=3(5)

L=15

Answer:

85%

Step-by-step explanation:

Which of the following could represent cross sections of a rectangular prism? A. Rectangle and hexagon B. Rectangle and circle C
DanielleElmas [232]

Answer:

C. Rectangle and Cube

Step-by-step explanation:

It's actually pretty easy to figure this out because all you have to do is look at the shape, and try to find what to shapes made this figure. When you look at a cuboid (rectangular prism), you can see how the answer choices have one 2D shape, and one 3D shape. Well after looking at the Cuboid, we can see that there are rectangles on the faces, and this would be the 2D shape, and then we have a big cube holding those faces together, and the cube would be our 3D shape.

Hope this helps :)

When you write “c” at the start, or x or whatever, it has an understood (invisible) number 1. So you’re subtracting the decimal on the next variable from 1.
