Scholar #2 is correct. You take 15=-3m-18+5m-7 and combie like terms. Which will leave you with 15=2m-25. You will simplify from there, getting 20=m.

Algebra!!!<br> 3 Questions Only take if you know ALL Answers<br> PLZZZ QUICK
vitfil [10]

Answer:

1. -7.5

2. $1

3. 40

Step-by-step explanation:

For number 1, it can be solved by using the PEMDAS method, or see explanation below:

6x - 4x - 36 = 6 - 2x

2x - 36= -2x + 6

4x + 36 = 6

4x = -30

x = -15/2 or -7.5

For number 2, substitute 3 into both equations:

f(x) =1.50(3) + 2.00

and

f(x) = 2.00(3) + 1.50

This would get $6.50 and $7.50, which, if subtracted, gets $1.

For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.

Hope this helps!

Skylar makes turkey sandwiches for a family reunion. He purchases 5 pounds 4 ounces of sliced turkey for $26.88. What is the uni
Advocard [28]

Answer:

The unit cost per ounce for turkey skylar is $ 0.316  

Step-by-step explanation:

The total amount of sliced turkey = 5 pounds + 4 ounces

The total cost of turkey slice = $26.88

Now, as we know

1 pounds = 16 ounces

∴ 5 pounds = 16 × 5 = 80 ounces

So, the total amount is 5 pounds + 80 pounds = 85 pounds

∵ 85 pounds of turkey sliced cost $ 26.88

∴ 1 pounds of turkey sliced cost $ \frac{26.88}{85}  = $ 0.316

Hence the unit cost per ounce for turkey skylar is $ 0.316  Answer
