Answer:
x = 5/(a-b+3)
Step-by-step explanation:
ax+3x=bx+5
Collect all the terms that has x:
ax-bx+3x = 5 (Subtracting bx both sides)
Take out the x!
x(a-b+3) =5
Divide (a-b+3) both sides to solve for x
x = 5/(a-b+3)
Hope this helps!
Would really appreicate the brainliest!

Answer:
B
Step-by-step explanation:
f(x) - g(x)
= 2x² - 4x - 3 - (x - 4)(x + 4) ← expand using FOIL
= 2x² - 4x - 3 - (x² - 16) ← distribute by - 1
= 2x² - 4x - 3 - x² + 16 ← collect like terms
= x² - 4x + 13 → B

Answer:
17
Step-by-step explanation:
Let the amount of roses in the second yard be x. This means that the number of roses in the first yard would be x-10. If nine roses were transplanted from the second yard to the first one, the number of roses in the second yard would be x-9 and the number of roses in the first yard would be x-1. It is stated that now, there would be 2 times more roses in the first yard than the second one, which means that 2(x-9) = x-1, which simplifies to 2x-18 = x-1. Subtract both sides by x, and we get x-18 = -1. Add 18 to both sides, and we get x = 17, therefore, there are 17 roses in the second yard.
