Answer:
I'm sorry but what is the question?
Step-by-step explanation:
Seven-thirty.
A half an hour past seven o'clock.
Step-by-step explanation:
cross multiply
2x - 4 = 4 × 5
2x - 4 =20
collect like terms (CLT)
2x = 20 + 4
2x=24
divide both sides by 2
x=12
Answer:
x= 6
Step-by-step explanation:
Isolate all variables on their own and numbers on the other
5x -4x +7-7 = -1 +7 +4x -4x
5x -4x = -1+7
Solve for x
x = 6
That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= <span>(7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= </span>7w^3 - 4w + 3 + 5w^3 - 3w - <span>3
= 12w^3 - 7w
= w(</span><span>12w^2 - 7</span>)
