Answer:

x= 1/2 and -3/4

Step-by-step explanation:

By using factorization, we can solve this equation.

8x^2+2x-3=0

Factor:

(2x-1)(4x+3)=0

Solve:

2x-1=0

2x=1

x=1/2

Solve again:

4x+3=0

4x=-3

x=-3/4

Dan spends 2 5 of his wages on rent and 1 2 on food. If he makes ?430 per week, how much money does he have left?
BartSMP [9]

Answer:

Dan would be left over with $43 a week.

Step-by-step explanation:

\frac{2}{5} = 40%

\frac{1}{2} = 50%

Rent: $430 - 40% = $172

Food: $430 - 50% = $215

$215 + $172 = $387

$430 - $387 = $43

KatRina [158]

Let's solve  your equation step-by-step

16.8-(-23.72)-31.3=x

Step 1:simplify both sides of the equation

16.8-(-23.72)-31.3=x

16.8+23.72+-31.3=x

(16.8+23.72+-31.3)=x (combine like terms)

9.22=x

9.22=x

Step 2: flip the equation

Answer: x=9.22
