Brian has reduced his cholesterol level by 20% after his last check up. if his original level was 240, what is his cholesterol level now?

Step-by-step explanation:

Given:

Reduced level of cholesterol = 20%

Original level of cholesterol = 240

We need to find cholesterol level now

Solution:

First we find reduced level of cholesterol using percentage formula.

Substitute all known value in above formula.

So reduced level of cholesterol = 48

But we need to find cholesterol level now, so we subtract reduced level from original level of cholesterol.

Therefore, Cholesterol level at present = 192

i really dont know

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
