It’s a good idea to get into the habit of using parentheses

when substituting numbers in for variables.

If you have parentheses in your original problem, change them to brackets as you substitute (to avoid confusion).

Now plug in the values for b and c into the problem.

So we have [(-5) + (-3)].

Simplifying inside the brackets, we get [(-8)].

So -8 is the answer.

The ratio of the measures of the angles of a triangle is 4:6:8. Find the measure of the largest angle.
garri49 [273]

Answer:

80°

Step-by-step explanation:

The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:

4x + 6x + 8x = 180

18x = 180

x = 10 which means the largest angle (8x) = 8 * 10 = 80°

Determine if the following equation has "One Solution", "No Solutions", or "Infinite Many Solutions".
Novosadov [1.4K]
First, distribute the 2.
2x+6=6+2x
These are the same, so therefore it is infinitely many, because whatever you plug in for x will work.
