Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir di
bezimeni [28]

1. An equation representing the number of days Amir has been reading and the number of pages he has read is <u>y = 35x</u>.

2. An equation representing the number of days Jesse has been reading and the number of pages she has read is <u>y = 30 + 30x</u>.

3. The system of equations from 1 and 2 is y = 35x and y = 30 + 30x.

4. At the end of Friday, after solving the equations, both Jesse and Amir read <u>210 pages each</u>, with Jesse spending <u>7 days</u> and Amir <u>6 days</u>.

5. For Jesse and Amir, the equation solutions are <u>y is 210</u> pages and <u>x is 6 days</u>.

6. After solving the equations, it will take Amir <u>6 days</u> to catch up with Jesse and each person must have read <u>210 pages</u> or a total of <u>420 pages</u>.

<h3>What is a system of equations?</h3>

A system of equations involves using more than one equation solved simultaneously.

Jesse's reading rate per day = 30 pages

Amir's reading rate per day = 35 pages

The number of pages read by Jesse, y = 30 + 30x

The number of pages read by Amir, y = 35x

Where x = the number of days they have been reading

<h3>Solving the equations:</h3>

y = 30 + 30x and y = 35x

35x  = 30 + 30x

35x - 30x = 30

5x = 30

x = 6 (30/5)

<h3>Jesse:</h3>

y = 30 + 30x

y = 30 + 30(6)

y = 210

<h3>Amir:</h3>

y = 35x

y = 35(6)

y = 210

Josie deposited $450 at the beginning of the month. A payment of $35.20 is automatically deducted each month for her gym members
Alinara [238K]

Answer:

You have told us that there is $450 in Josie's bank account, and she does not make any later deposits or withdraws. You have also told us that the gym deducts $35.20 every one month in fees.

Explanation:

The answer is really easy to find. All you have to do is subtract 35.20 from 450. The problem asks for the amount of money that Josie has in her account at the end of the month - the same month that she put $450 into her account.

Solve:

450 - 35.20

= 414.80

Josie has $414.80 in her bank account at the end of the month.

I DONT NEED SLEEP I NEED ANSWERS
stellarik [79]

Answer:

You asked to solve questions 3 and 5

<h3>#3</h3>

Since CD = EF,

  • 9x - 1 = 41 - 5x
  • 9x + 5x = 41 + 2
  • 14x = 42
  • x = 3
  • EF = 41 - 5*3
  • EF = 26
<h3>#5</h3>

MN = NP as their perpendicular bisectors are of same length.

  • 9x - 43 = 5x + 33
  • 9x - 5x = 33 + 43
  • 4x = 76
  • x = 19
  • mMP = 360 - (mMN + mNP)
  • mMP = 360 - (9*19 - 43 + 5*19 + 33)
  • mMP = 104
