(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
Answer:
25
Step-by-step explanation:
We require to solve for n, hence
n(n + 1) = 325
multiply both sides by 2 to eliminate the fraction
n(n + 1) = 650
n² + n = 650
subtract 650 from both sides to have equation in standard form
n² + n - 650 = 0 ← in standard form
(n + 26)(n - 25) = 0 ← in factored form
equate each factor to zero and solve for n
n + 26 = 0 ⇒ n = - 26
n - 25 = 0 ⇒ n = 25
however, n > 0 ⇒ n = 25
Answer:
You paid $40.25 in total.
Step-by-step explanation:
In this question:
Spending of 35%
Tip of 15% means that 15% of 35 will be added to your total spending. So
![T = 35 + 0.15*35 = 35 + 5.25 = 40.25](https://tex.z-dn.net/?f=T%20%3D%2035%20%2B%200.15%2A35%20%3D%2035%20%2B%205.25%20%3D%2040.25)
You paid $40.25 in total.
-65=6b-11
Add 11 to both sides to get rid of the -11 on the right side
-54=6b
Then divide both sides by six to find the value of b
-9=b
So b is -9
