-6(a+8) how do I simplify ?

Answers

Answer:

-6a-48

Step-by-step explanation:

distribute

Use the Distributive Property:

You "distribute" -6 into the equation by multiplying it by each number in the parentheses.

-6(a+8)
1) multiply -6 by a, which equals -6a
2) multiply -6 by 8, which equals -48

Your equation should be -6a-48

From there, it can be seen that you can divide -6 from each number in the equation.
-6a/-6 just leaves you with a
-48/-6 gives you 8

a-8

Last week, Bill ran 900 meters on each of 3 days. Between last week and this week, bill wants to run a total of 6 kilometers. How far does bill need to run this week?A. 4.7 kilometers
B. 2.7 kilometers
C. 3.3 kilometers
D. 2.3 kilometers

Answers

For the 3 days he ran a total of :  3 * 900 = 2700 meters.

1000 meters = 1 kilometers

2700 meters = 2700 / 1000 = 2.7 kilometers.

Between last week and this week, Bill ran a total of 6 kilometers.

How far he ran this week = 6 - 2.7 = 3.3 kilometers.

#18 how would u not multiplying to find which is grater

Answers

In the first product the numerator of the fraction is greater than the denominator, therefore the fraction is greater than 1. On the other hand in the second product the numerator of the fraction is smaller than the denominator, therefore the fraction is smaller than one. That means the first product is greater than the second one.

figure out which fraction is larger first by making a mixed number:9 1/6 them find least common denominator between 6 and 10 to compare the two fractions. once you got that which numerator is larger. if that made no since sorry
