Help! I'm not sure how to set this up. Here is the question; Faye paid $16.00 for a pair of shorts that were 20% off. What was the original price of the shorts.

9514 1404 393

Answer:

  2335.515

Step-by-step explanation:

The first increase multiplies the original amount by 1 + 5% = 1.05.

The second increase multiplies the already increased amount by 1 + 18% = 1.18.

Then the final amount is ...

  1885(1.05)(1.18) = 2335.515

Answer:

11= EC

Step-by-step explanation:

EC = 10 + 2 x + 19

= x + 20

So 2 x + 29 - x - 20 = 0

so x + 9 = 0

x = -9.

EC = x + 20 = -9+20 = 11.

Answer:

EC = 11 units

Step-by-step explanation:

• first we find the value of x

10 + 2x + 19 = x + 20

2x - x = 20 - 10 - 19

x = -9

--------------------------------

check

10 + 2(-9) + 19 = -9 + 20

10 - 18 + 19 = -9 + 20

11 = 11

same value the answer is good

• Now we find EC

EC = 10 + 2x + 19

EC = 10 + 2(-9) + 19             (remember PEMDAS)

EC = 10 - 18 + 19

EC = 11 units

Answer:

1. y = -4x + 2

Now, we can substitute this expression for y into the second equation:

2. x - 2y = 23

Substitute the value of y from equation 1 into equation 2:

x - 2(-4x + 2) = 23

Now, simplify and solve for x:

x + 8x - 4 = 23

Combine like terms:

9x - 4 = 23

Add 4 to both sides:

9x = 27

Divide by 9:

x = 3

Now that we have found the value of x, substitute it back into equation 1 to find y:

y = -4x + 2

y = -4(3) + 2

y = -12 + 2

y = -10

So, the solution to the system of equations is:

x = 3

y = -10

Answer: 5.50

Step-by-step explanation:

1.50 + 1.00 = 2.50 . 8.00 - 2.50 = 5.50
