Answer:

<u>Y is the midpoint of XZ, so XY = YZ</u>

  • 20x - 30 = 12x + 10
  • 20x - 12x = 10 + 30
  • 8x = 40
  • x = 5

<u>Find XZ:</u>

  • XZ = 2(XY) = 2(20*5 - 30) = 140

<u>The answer is: </u>

  • x = 5 and XZ = 140

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

<u>B is the midpoint of AC, so AB = BC</u>

  • 4x + 3 = 2x + 15
  • 4x - 2x = 15 - 3
  • 2x = 12
  • x = 6

<u>Find AC:</u>

  • AC = 2(AB) = 2(4*6 + 3) = 54

<u>The answer is:</u>

  • x = 6, AC = 54

You need to design a rectangle with a perimeter of 14.2 cm. The length must be 2.4 cm. What is the width of the
irina1246 [14]

Part (a)

<h3>Answer: 2(2.4+w) = 14.2</h3>

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

Explanation:

L = 2.4 = length

W = unknown width

The perimeter of any rectangle is P = 2(L+W)

We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2

========================================================

Part (b)

<h3>Answer:   w = 4.7</h3>

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

Explanation:

We'll solve the equation we set up in part (a)

2(2.4+w) = 14.2

2(2.4)+2(w) = 14.2

4.8+2w = 14.2

2w = 14.2-4.8

2w = 9.4

w = 9.4/2

w = 4.7

The width must be 4.7 cm.

Hakim invests $700 in a bank that pays 5% simple interest annually. After one year he uses the money in his account to buy a com
ludmilkaskok [199]

Answer:

  $111

Step-by-step explanation:

The bank balance is ...

  $700 × (1 + 0.05) = $735

The cost of the computer is ...

  $750 × (1 -0.20) × (1 +0.04) = $624

The remaining bank balance after paying for the computer is ...

  $735 -624 = $111

_____

When you add a percentage, you effectively multiply by the sum of 1 and that percentage. The same is true if the amount "added" is negative (as for a discounted price).

  (original amount) + (percentage)×(original amount)

Use the distributive property to factor out the original amount:

 = (original amount)×(1 + percentage)
