Answer:
2w - 13
Step-by-step explanation:
here we just simplify the expression,
3w - 4 - w - 9
becomes:
2w - 13

Answer:
<u>The negative solution is -4</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
x = a number
4x = x² - 32 (4 times a number is 32 less than the square of that number)
2. Let's solve for x and find the negative solution:
4x = x² - 32
-x² + 4x + 32 = 0
x² - 4x - 32 = 0 (Multiplying by - 1)
(x - 8) (x + 4) = 0
(x₁ - 8) = 0
(x₂ + 4) = 0
x₁ = 8
<u>x₂ = -4</u>
<u>The negative solution is -4</u>
Answer:
There are a few possible answers so read explanation, but the one I will put up here is:
20.83
Step-by-step explanation:
First you have to find how much 100 cups of coffee costs in store.
To do this you will multiply 2.50 by 100 and get 250. So now we know 100 cups of coffee in store costs $250 whereas 100 cups at home is $12.
To find how many times greater the price in store is compared to the at home brew, you have to divide 250 by 12 and get 20.8333333....
We don't stop there though, because it asks us to approximate. I am not sure what it would like us to round to, but here are some possible approximations:
- 20.83
- 20.8
- 21
Any of those re reasonable approximations, you choose whichever you think the question wants, or whatever your teacher asks for.
Hope this helps
