Answer: is 36
Step-by-step explanation:
Apply the distributive property, which says that a(b+c)= ab+ac.
-2(x+7)= -2(x)+ -2(7)
-2(x)= -2x
-2(7)=-14
Put it together.
Final answer: -2x-14
A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.
So if the profit (p) is $170.00,
170 = 8n - 30
Now you need to solve.
Add 30 to both sides.
200 = 8n
Divide both sides by 8.
25 = n
25 items were bought.
b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160
The profit decreased by 10.
-0.2
'0
-0.2 = - .2 = - 2/10 = - 1/5
so
answer is -1/5
1 is 9,000 just round up or down and then mulitpy
2 is 6,400
3 is 11,100
4 is 1,200
5 is 189,000
6 is 6,300
7 is 53,000
8 is 4,300
9 is 7,800
that all i can do they might not all be right
