Answer:

3:2

Step-by-step explanation:

We know this because we can simplify both by 2, which gives 21:14. We're not done yet. 21:14 is divisible by 7, so we get 3:2

xeze [42]

Answer:

A)  See attached.

B)  Cheryl owes the bank more.

Step-by-step explanation:

Given account balances:

  • John:  -$2.75
  • Cheryl:  -$3.00
  • Andrew:   $2.75

(Andrew has as much savings in his account as the amount John owes).

<h3><u>Part A</u></h3>
  • Draw a straight, horizontal line with arrows on both ends.
  • Place a tick in the center of the line and label it zero.
  • Draw 4 evenly spaced ticks either side of the zero.
  • Number the ticks to the right of the zero 1, 2, 3 and 4.
  • Number the ticks to the left of the zero -1, -2, -3, and -4.
  • Mark -2.75, -3 and 2.75 on the number line.
  • Label the marks with John, Cheryl and Andrew.

(See attached number line).

<h3><u>Part B</u></h3>

The <u>absolute value</u> of a number is its <u>positive numerical value</u>.

To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:

  • John:  |-2.75| = 2.75
  • Cheryl:  |-3.00| = 3.00

As 3.00 > 2.75, Cheryl owes the bank more.

Someone help please :(
Hunter-Best [27]

Answer:

Answers in step-by-step.

Step-by-step explanation:

We are going to make Sarah the variable "s."

Using the given information, the following equation is derived to calculate Sarah's distance.

  • S=2n-5

And the following equation will be used to calculate what Sarah collected using "p" for pledged money.

  • P=18S

If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.

  • P=18S
  • 450=18S
  • 450/18=S
  • 25 miles = S

Using Sarah's distance, we can calculate Semir's either the first equation.

  • S=2n-5
  • 25=2n-5
  • 30=2n
  • 15=n
  • Semir walked 15 miles.

We already found Sarah's distance to be 25 miles.

Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.

  • 450-72=$378

His formula is the same as Sarah's, but we'll use SS for his variable.

  • P=18SS
  • 378 = 18SS
  • 378/18=SS
  • 21= SS
  • SungSo walked 21 miles.
