Answer:
Ok:
Step-by-step explanation:
I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.
Answer:
7 * 1/8

7 is a whole number
A unit fraction has the top number equal to 1, so we can use 1/8

Step-by-step explanation:
This is asking you to recognize the symbols used to designate a point, line segment, ray, angle, line, and plane.
The point is designated by its letter.
A line segment is designated by the letters of its endpoints, with an overline.
A ray is designated by the endpoint and a point on the ray. The endpoint is listed first. The letters have an arrow over them pointing in the direction from the endpoint.
An angle is designated using the symbol ∠. If three letters are used to identify the angle, the middle one is the vertex.
A line is designated using its name, or by the letters of two points on the line. If the letters are used, there may be a double-ended arrow over them.
A plane is designated by 3 non-collinear points, for example, "plane ABC". It may also be designated by the name of the plane.
y + 2x < 4x - 3 <em>subtract 2x from both sides</em>
y < 2x - 3
y = 2x - 3
for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)
