Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
Answer:
3 1/2 gallons of paint
Step-by-step explanation:
1 5/8 - 5/6 = x
Turn the mixed number into an improper fraction:
1 5/8 = 13/8 = x
13/8 - 5/6 = x
make the denominator the same:
13/8 * 3 = 104/24
5/6 * 4 = 20/24
Subtract:
104/24 - 20/24 = 84/24
Simplify:
84/24 divided by 6 = 14/4
14/4 divided by 2 = 7/2
Turn into a mixed number:
3 1/2

I believe that it will take one day
200-(25•2)=150
150-(22•3)=84
84-25=59

Answer:
45.1
Step-by-step explanation:
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
