A student has $350.00 in her account and withdrew 3/5 of it . how much money , in dollars, remains in the account
Burka [1]

a whole, fraction wise, is always 1, so in this case we're looking at a whole of 5/5 = 1, and she withdrew 3/5, so what remained is 2/5

\cfrac{5}{5}\qquad \qquad \cfrac{5}{5}-\cfrac{3}{5}\implies \cfrac{5-3}{5}\implies \cfrac{2}{5}~\hfill 350\left( \cfrac{2}{5} \right)\implies \boxed{140}

Answer:

So the top right answer choice (x - 10)² = 80 has the same solution as x² - 20x + 20 = 0

Step-by-step explanation:

Let's solve your equation step-by-step.

x² − 20x + 20 = 0

For this equation: a = 1, b = -20, c = 20

1x² + −20x + 20 = 0

Step 1: Use quadratic formula with a = 1, b = -20, c = 20.

x = −b ± √b² − 4ac / 2a

x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)

x = 20 ± √320 / 2

x = 10 + 4√5 or x = 10 − 4√5

Let's try the top right answer choice

(x−10)² = 80

Step 1: Simplify both sides of the equation.

x² − 20x + 100 = 80

Step 2: Subtract 80 from both sides.

x² − 20x + 100 − 80 = 80 − 80

x² − 20x + 20 = 0

For this equation: a = 1, b = -20, c = 20

1x² + −20x + 20 = 0

Step 3: Use quadratic formula with a = 1, b = -20, c = 20.

x = −b ± √b² − 4ac / 2a

x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)

x = 20 ± √320 / 2

x = 10 + 4√5 or x = 10 − 4√5
