Find the ratio of black cell phone covers sold to the total number of cell phones covers sold last week. then explain its meaning = info below
green cover : 5
silver cover: 6
red cover: 3
black cover: 4

The correct answer is:

4:18, which means that 4 out of every 18 covers sold are black.

Explanation:

To find the ratio of black cases to total, we must first find the total number of cases sold: 5+6+3+4 = 18.

This makes the ratio of black to total 4:18.

The explanation is that 4 cases out of every 18 will be black.

46.2+112.3

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
