Original price = $30
Increase in 50% = 50% of $30 = 0.5 x 30 = $15
Price = 30 + 15 = $45

50% off 
50% of $45 = 0.5 x 45 = $22.50
Price = 45 - 22.50 = $22.50

No, the sales price is not $30

Each night Ann and her family empty their pockets, purses, and wallets and place all of the pennies, nickels, dimes, and quarter
Sedaia [141]
The easiest way to solve this is to take the amount of each coin and multiply it by its value. Afterwards add each total together to determine the amount of money that Ann has.

145 pennies X $0.01 = $1.45

42 dimes X $0.10 = $4.20

12 quarters X $0.25 = $3.00

$1.45 + $4.20 + $3.00 = $8.65

Therefore Ann has $8.65

Which sequence is represented by = 10 − 29 where x represents the term number and y represents the term?
lina2011 [118]

Answer:

X = 18

Step-by-step explanation:

Question: The sum of three numbers in order is 57. the equation that represents this is x (x 1) (x 2) = 57. which value of x from the set {16, 17, 18, 19} makes the equation true?

Answer: First you can use the equation to work out the value of x.

x + (x + 1) + (x + 2) = 57

Simplify the equation.

3x + 3 = 57.

Now solve the equation.

57 - 3 = 54

54/3 = 18

In short, The value of x is 18.

What is the answer for 10x+75+5x=110? And how do you get it?
cestrela7 [59]
Okay, let's add the two x values.
10x + 75 = 5x = 110
15x + 75 = 110

Now let's minus 75 from each side.
15x = 35

Now let's divide each side by 15.
x = 2.333333333
