Answer:
prism
Step-by-step explanation:
The figure will not be a cube, because a cube does not have any triangular faces.
The figure will not be a pyramid, because a pyramid has a triangular face for each edge of the base.
The figure will not be a triangle, because a triangle is a plane figure.
The figure will be a triangular <em>prism</em>: a figure with parallel bases, each having 3 edges, and a rectangular face associated with each of those edges.
Answer:
420 miles
Step-by-step explanation:
To start, let's find the distance between A and B when they both start moving. This is two hours after the car starts moving, and that is 2*60=120 miles. There are 620 miles total, so they are 500 miles apart when they both start moving. Notice that they are moving in opoposite directions, so every hour they will get 60+40=100 miles closer to each other, so it will take 500/100=5 hours to meet. To find the distance from city A, we need to find how far the car moved, which is just 2+5=7 hours times 60 mph or 420 miles away from city A.

Answer:
x = 1
Step-by-step explanation:
For the equation given, we have to solve for the value of "x".
First, when simplifying, we will need the distributive property shown below:
<u>Distributive Property:</u>
a(b - c) = ab - ac
Now, lets do algebra:
![-x + 3 = 2(3 - 2x)\\-x+3=2(3)-2(2x)\\-x+3=6-4x\\-x+4x=6-3\\3x=3\\x=\frac{3}{3}\\x=1](https://tex.z-dn.net/?f=-x%20%2B%203%20%3D%202%283%20-%202x%29%5C%5C-x%2B3%3D2%283%29-2%282x%29%5C%5C-x%2B3%3D6-4x%5C%5C-x%2B4x%3D6-3%5C%5C3x%3D3%5C%5Cx%3D%5Cfrac%7B3%7D%7B3%7D%5C%5Cx%3D1)
The value of x is 1
Lets substitute x = 1 into equation to check:
-x + 3 = 2(3-2x)
LEFT SIDE:
-(1) + 3
= -1 + 3
=2
RIGHT SIDE:
2(3-2x)
2(3-2(1))
=2(3-2)
=2(1)
= 2
<em>This is indeed the solution since left hand side equals right hand side</em>
