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

5x-4y=19 x+2=8 Solve simultaneous equation

xeze [42]

Answer:

x = 6, y = 5

Step-by-step explanation:

5x - 4y = 19 -------> equation 1

x + 2 = 8 --------> equation 2

Step 1 : Subtract 2 on both sides in equation 2.

x + 2 - 2 = 8 - 2

x = 6

Step 2 : Substitute the value of x is equation 1.

5 ( 6 ) - 4y = 19

( 5 * 6 ) - 4y = 19

30 - 4y = 10

Step 3 : Subtract 30 on both sides.

30 - 30 - 4y = 10 - 30

- 4y = - 20

Step 4 : Multiply - 1 on both sides.

- 1 * - 4y = - 1 * - 20

4y = 20

Step 5 : Divide 4 on both sides.

4y / 4 = 20 / 4

y = 5

Hence,

x = 6

y = 5

Question 1

Airida [17]

Answer:

a) There are Total 25 Question on the test.

Each question is worth 4 points.

b) Your friend answered 19 questions correctly.

Step-by-step explanation:

Given:

Question answered =24

Percent earn = 96%

Total point test = 100

We will first solve for part a.

We need to find Total Question on the test and Points worth each question.

Now We know that percent earn is equal to Question answered divided by Total Question on test and ten multiplied by 100.

Framing in equation form we get;

$Percent\ earn = \frac{\textrm{Question Answered}}{\textrm{Total question on test}}\times 100\\ \\\textrm{Total question on test} = \frac{\textrm{Question Answered}}{\textrm{Perecent earned}}\times 100$

Substituting the given values we get;

Total question on test = $\frac{24}{96}\times 100 =25$

Hence There are Total 25 Question on the test.

Now we will find each question worth points.

each question worth points can calculated by dividing Total Point test with total number of question on the test.

Framing the equation we get;

each question worth points = $\frac{100}{25} = 4\ points$

Hence Each question is worth 4 points.

Now Solving for part b.

Given:

Percent earn by friend = 76%

we need to find number of question answered correctly.

question answered correctly = $\frac{\textrm{Percent earned by friend}\times \textrm{Total Number of question}} {100}$

Substituting the values we get;

question answered correctly = $\frac{76\times 25}{100} = 19$

Hence Your friend answered 19 questions correctly.
