Answer:
Step-by-step explanation:
4a^5 - a + a^5 + 6a - 1
5a^5 + 5a - 1
The answer is 80%
1/5 of 100 is 20.
You find this by dividing 100 by 5 to get 20, then you subtract 20 from 100.
The sum is the total of the given values being added.
Given the expressions above, to add them, you just have to add the numbers with the same terms. 13x2 and 8x2 have the same terms which is x2, therefore, you can add both and the result is 21x^2 then just copy 5x so the sum would be 21x2 + 5x. Hope this answer helps.
Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5
y = -6
