Answer:

x=-5

Step-by-step explanation:

opening the bracket on the LHS, we have

-8x-40= -3x+x-7-3

-8x-40= -2x-10

collecting like terms

-8x+2x= -10+40

-6x= 30

divide both sides by -6

x= -5

Answer:$3,700

Step-by-step explanation:

Gross sales are the total amount of sales a company earned throughout a specific period of time, without taking into consideration any costs involved with running a business. Gross sales do not factor in expenses related to running a business, also known as cost of goods sold (COGS), which get deducted when calculating net sales. For example, they do not account for costs associated with item production, employee wages, building rent, returns, theft or sales tax.

Gross Sales = $3,700

Part A: Find the LCM of 7 and 12. Show your work. (3 points)
anyanavicka [17]

The LCM of 7 and 12 is 84 and GCF of 56 and 96 is 8, 56+96 can be written as 8(19).

<h3>What is LCM?</h3>

It is defined as the common number of two integers, which is the lowest number that is a multiple of the two or more numbers. The full name of LCM is the least common multiple.

LCM of 7 and 12:

7 can be divided by 7

Factor of 12 is 2×2×3

So the LCM = 7×2×2×3 = 84

For GCF:

We know:

GCF(56, 96) = (56×96)/LCM(56, 96)

GCF(56×96) = (56×96)/672 = 8

= (56 + 96)

= 8(7+12)

= 8(19)

Thus, the LCM of 7 and 12 is 84 and GCF of 56 and 96 is 8, 56+96 can be written as 8(19).
