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

Answers

Answer 1

Answer:

Answer:

-6a-48

Step-by-step explanation:

distribute

Answer 2

Answer: 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

Order 3/8,3/4,1/2,5/6 from least to greatest

Answers

To solve this, it is easiest to find the least common multiple of the denominators which is 24. Now we can rewrite our fractions.
$(3)/(8)$ = $(9)/(24)$
$(3)/(4)$ = $(18)/(24)$
$(1)/(2)$ = $(12)/(24)$
$(5)/(6)$ = $(20)/(24)$

Now these fractions can be put in order:
$(9)/(24)$ , $(12)/(24)$ , $(18)/(24)$ , $(20)/(24)$

Reduce and you have your answer.
$(3)/(8)$ , $(1)/(2)$ , $(3)/(4)$ , $(5)/(6)$

To order these, we need to get all of the to a common denominator.

3*3 = 9
8*3 = 24

9/24

3*6 = 18
4*6 = 24

18/24

1*12 = 12
2*12 = 24

12/24

5*4 = 20
6*4 = 24

20/24

Now, analyze these fractions and compare their numerators.

20/24 , 12/24 , 18/24 , 9/24

The least: 9/24
Greatest: 20/24

Final answer:

3/8 , 1/2 , 3/4 , 5/6

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Sandra has 18 bags of peanuts to hand out to 9 friends. The number of the peanuts bag will be calculated as,

Number = 18 / 9

Number = 2 bags

Therefore, the for each friend, there will be 2 numbers of peanuts.
