Answer/Step-by-step explanation:
Let's work out the subtraction of the polynomial to find out where the error is and the correct result we should have.
6x² - 4x - 5
- 3x² - 7x + 2
= [6x² - 3x²] [-4x -(-7x)] [-5 -(+2)]
= 3x² + 3x - 7
The error that was made in the subtraction given in the question was that the negative signs before the terms, 7x and 5 were ignored while subtracting.
The sign is very important, it defines the value of the term.
We can choose to solve the problem in another way shown below:
(6x² - 4x - 5) - (3x² - 7x + 2)
Distributive the negative sign in the second polynomial
6x² - 4x - 5 - 3x² + 7x - 2
Combine like terms
6x² - 3x² - 4x + 7x - 5 - 2
3x² + 3x - 7
Alright, lets get started.
Maria hiked the 5 mile Mountain Trail a number of times and she hiked the 10 mile canal trail several times.
x times she hiked 5 mile mountain.
So, number of mils she hiked for 5 miles will be = 5 x
Similarly,
y times she hiked 10 mile canal,
So, number of miles she hiked for canal = 10 y
So, total number of miles she hiked = 
But as per question given, she had a total of 90 miles
It means
Dividing this equation with 5
So, the equation is : Answer
Hope it will help :)
Answer:
x=1
Step-by-step explanation:
(5x+−2x)+(3+−2)=4
3x+1=4
3x=3
x=1
<span>94 is 117.5% of 80 is your answer</span>
Answer: As a decimal it would be .136. You can write it as a decimal by dividing by 100 as you would need to get this total by multiplying by 100. Just reverse the steps into making a percentage.
Example: 70 out of 200.
You'd do 70 divided by 200 and get .35.
After, you would multiply by 100 to turn it into a percentage.
If you want to turn it into a decimal divide by 100.
