Zachary purchased a computer for $1,300 on a payment plan. Two months after he purchased the​ computer, his balance was $1,100.
raketka [301]

Answer:

y = 1300 - 100x

Step-by-step explanation:

Zachary purchased a computer for $1300

The first step is to calculate the purchase he paid after 2 months

= 1,300-1,100

= $200

Then the purchase after 1 month is

= $200/2

= $100 per month

The purchase made after 4 months is

= 1,100-900

= $200

The purchase after a month is

= $200/2

= $100 per month

Therefore the equation that models the balance y after x months is

= initial amount of payment plan - amount per month

y= 1,300 - 100x

3) Valerie works at a local amusement park. She earns $9.80 per hour. She 20 points
NemiM [27]
<h3>Answer:  Choice A</h3><h3>9.80h+10 = 88.40</h3>

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

Work Shown:

  • h = number of hours worked.
  • 9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).
  • 9.80h+10 = total amount of money earned after adding on the meal bonus.
  • 9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.

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

Extra info (optional section)

If you want to solve for h, then you could follow these steps.

9.80h+10 = 88.40

9.80h = 88.40-10 ... subtract 10 from both sides

9.80h = 78.40

h = 78.40/9.80 .... divide both sides by 9.80

h = 8

Valerie worked 8 hours on Friday.

As a check,

9.80h + 10 = 88.40

9.80*8 + 10 = 88.40

78.40 + 10 = 88.40

88.40 = 88.40

The answer is confirmed.

Back to back questions sorry
yaroslaw [1]

Answer:

  • x = 115°.

Step-by-step explanation:

<u>All angles should make 180°.</u>

<u>So, we subtract: 180 - 40 - 25.</u>

  • 180 - 40 = 140
  • 140 - 25 = 115.
  • x = 115°.

<u>If it adds over or under 180°, then you subtracted the wrong numbers or subtracted in the wrong order.</u>
