Answer:  b = 5

Step-by-step explanation:

Here parallelogram wxyz has diagonals,

4b-6 and 2b+4

Since, If a parallelogram has a equal pair of congruent or equal diagonal it is called a rectangle.

Thus, if wxyz is a rectangle,

Then, 4 b - 6 = 2 b + 4

⇒ 4b = 2 b + 4 + 6

⇒ 4 b = 2 b + 10

⇒ 4 b - 2 b = 10

⇒ 2 b = 10

⇒ b = 5

Hence, for b = 5,  wxyz is a rectangle.

Use the original price and the markup to find the retail price.
Ber [7]

Answer:

$45.15

Step-by-step explanation:

When you are dealing with questions with percents in them—like this one—you have to turn the percent into a decimal. To make 7.5% into a decimal, you move the decimal point 2 spaces to the left. So, 7.5% is also 0.075.

Now, we have to use this formula for these types of questions:

x + x(y)= the price with tax (or markup)

So, we can substitute the variables.

42+42(0.075)=the retail price

42(0.075)=3.15

42+3.15=45.15

So, the retail price will be $45.15

If You can pls answer all 4 with the equations
Trava [24]

9514 1404 393

Answer:

  1. 69
  2. 100
  3. -24
  4. 1/729

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic. Your calculator can help.

1. 6x -2y +5y = 6(10) -2(3) +5(3) = 60 -6 +15 = 69

__

2. add 16 to find x.

  x -16 = 29

  x = 45

Then do the substitution:

  2(45 +5) = 2(50) = 100

__

3. 3(4²) -4(18) = 3(16) -4(18) = 48 -72 = -24

__

4. (1/9)³ = (1/9)(1/9)(1/9) = 1/(9·9·9) = 1/729
