Answer:
3
Step-by-step explanation:
15-2x=3x
or,3x+2x=15
or,5x=15
or,x=15/5
Therefore, x=3.
Answer:
If your trying to solve with exponents, the only answer I got was 6/y^4.
Step-by-step explanation:
Six out of y four.
I wasn't even sure so I checked it and that is what I got.
Lets get started :)
a) m(x) = (x - 5)(3 + 2x) - x² + 25
↓
Open Brackets
↓
= (x × 3) + (x × 2x) + (-5 × 3) + (-5 × 2x) - x² + 25
= 3x + 2x² - 15 - 10x - x² + 25 (Bring like-terms together in descending power order)
= 2x² - x² + 3x - 10x - 15 + 25
= x² - 7x + 10
b) In x² - 7x + 10, -7 is the sum and + 10 is the product
- 2 + - 5 = -7
- 2 × -5 = 10
So the factor of x² - 7x +10 is:
↓
(x - 2)(x - 5)
Solving ( x - 2 )( x - 5 ) = 0
↓ ↓
x - 2 = 0 | x - 5 = 0
x = 2 | x = 5

Hope your day or night is good well!
The correct answer is A
Hope this helps you out!

Answer:
n = m r - r t
Step-by-step explanation:
Solve for n:
m = n/r + t
Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.
m = n/r + t is equivalent to n/r + t = m:
n/r + t = m
Hint: | Isolate terms with n to the left hand side.
Subtract t from both sides:
n/r = -t + m
Hint: | Solve for n.
Multiply both sides by r:
Answer: n = m r - r t
