Answer:
Step-by-step explanation:
you do the ( ) first then you do plus and get the answer
120+.5x=50+.7x
Subtract 50 from both sides and then subtract .5x from both sides to get 70=.2x. Then divide both sides by .2 to get x=350.
Answer:
1/4x - 3 = 12
Step-by-step explanation:
When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:
1/4x - 3 = 12

Answer:
Step-by-step explanation:
Let α be one of the zeros of the polynomial.
Other = 4α
α + 4α = - Coefficient of x / Coefficient of x² = -5/3
5α = -5/3
α = -5/3*5
α = -1/3
α * 4α = Constant term/Coefficient of x²
4α² = k / 3
