Is it true rays continue infinitely in two directions

This is false. A ray has a definite starting point from which it continues infinitely in one direction only.
A line is a geometric construct which continues infinitely in two directions, and a segment has two definite starting and ending points.
False is the correct answer.
Hope that helped! =)

Why not? If 4 + 6 = 10, does (4 + 6) X 3 = 10 X 3? Why or why not?

Answer:

It would be 10*3

Step-by-step explanation:

If we follow the rule of BIDMAS or BODMAS, they both have Brackets to be done first.

By meaning we must do 4+6 as it is in the bracket. Then we multiply our answer by 3.

A dump truck brought 1⁄3 of a ton of rock on the first trip, 1⁄2 of a ton on the second trip, but on the third trip, had to take

Allisa [31]

Answer:

1/30 of a ton

Step-by-step explanation:

Write this as an expression:

1/3 of a ton and 1/2 of a ton were taken to the site.

4/5 of a ton were remove from the site.

Amount of a ton at the site = $\frac{1}{3}+ \frac{1}{2}- \frac{4}{5}$

Solve the equation by finding common denominators (when the bottom numbers are the same).

$(\frac{1}{3}+ \frac{1}{2})- \frac{4}{5}$ Focus on the first part. The least common multiple (LCM) of 3 and 2 is "6", which will become the denominator.
