The answer is A). 20% is equal to 1/5. So 20*5=100, so you be able to divide it by 2 and get 50. From there you would find how much money is spent.

Find x helpppppppppppp

lidiya [134]

$|2x - 1| = | - x - 2|$

Thus ;

$2x - 1 = - x - 2$

Add both sides x

$2x + x - 1 = - x + x - 2$

$3x - 1 = - 2$

Add both sides 1

$3x - 1 + 1 = - 2 + 1$

$3x = - 1$

Divide both sides by 3

$\frac{3x}{3} = \frac{ - 1}{3} \\$

$x = - \frac{1}{3} \\$

$2x - 1 = - ( - x - 2)$

$2x - 1 = x + 2$

Subtract both sides x

$2x - x - 1 = x - x + 2$

$x - 1 = 2$

Add both sides 1

$x - 1 + 1 = 2 + 1$

$x = 3$

There u go ...

Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run

Colt1911 [192]

Answer:

154.8

Step-by-step explanation:

20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.

Equation: 20/100= 0.2

0.2* 129= 25.8

25.8+129= 154.8

Alan ran 154.8 laps.
