Consider the expressions (3m + 2n - 6 and (-4-6m + 7n).
What is the sum of the expressions for n=-2 and m=5?
Answer:
-43
Step-by-step explanation:
The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.
What is an expression?An algebraic expression consists of unknown variables, numbers and arithmetic operators.
Given are two expressions, (3m+2n-6) and (-4-6m+7n)
Putting m = 5 and n = -2, we get,
(3m+2n-6) = 3x5-2x2-6 = 15-4-6 = 15-10 = 5
(-4-6m+7n) = -4-6x5-7x2 = -4-30-14 = -30-18 = -48
(3m+2n-6) + (-4-6m+7n) = -48+5 = -43
Hence, The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.

I NEED HELP PLEASE!!! An investor has an account with stock from two different companies. Last year,
her
stock in Company A was worth $2300 and her stock in Company B was worth $3080.
The stock in Company A has decreased 9% since last year and the stock in Company
B has decreased 25%. What was the total percentage decrease in the investor's stock
account? Round your answer to the nearest tenth (if necessary).
Answer:
81.8%
Step-by-step explanation:
Last year:
Company A stock + Company B stock = total amount of stock:
$2300 + $3080 = $5380
This year:
Company A stock: 2300 - (2300*0.09) = 2093
Company B stock: 3080 - (3080*0.25) = 2310
Company A stock + Company B stock = total amount of stock:
$2093 + $2310 = $4403
Total amount of decrease from last year:
[tex]\frac{4403}{5380} * 100 = 81.8[/tex] percent

1 - (2x + 9) = 4(21 - 2)
Answer:
x = 42
Step-by-step explanation:
1 - (2x + 9) = 4(21 - 2)
Distributive property ( multiply whatever is in the parenthesis by (-) for the first one, and (4) for the second one)
1 - * 2x + - * 9 = 4 * 21 - 4 * 2
1 - 2x - 9 = 84 - 8
Combine like terms
-8 - 2x = 76
Add 8 on both sides
-8 + 8 - 2x = 76 + 8
2x = 84
Divide by 2 on both sides to isolate the variable
2x/2 = 84/2
x = 42
