Answers

Answer

5.56

Step-by-step explanation

The price of one ice cream cone is $2.38

The given parameters;

the money given by Mrs Magee for the 3 ice cream cones = $10the change given to Mrs Magee = $2.86

The actual amount Mrs Magee purchased the 3 ice cream cones;

Total amount paid = $10 - $2.86 = $7.14

The price of one ice cream cone is calculated as follows;

[tex]Price \ of \ each = \frac{Total \ cost}{total \ number } \\\\Price \ of \ each = \frac{\$7.14}{3} = \$2.38[/tex]

Thus, the price of one ice cream cone is $2.38

If R is the midpoint of QS, find QS. (2x + 16) and (5x - 17) Brainliest to correct answers. Please no spamming or random answers this is due tmrw thx.

Answers

Answer:

QS = 76

Step-by-step explanation:

Given R is the midpoint of QS , then

RS = QR , that is

5x - 17 = 2x + 16 ( subtract 2x from both sides )

3x - 17 = 16 ( add 17 to both sides )

3x = 33 ( divide both sides by 3 )

x = 11

Then

QS = QR + RS

     = 2x + 16 + 5x - 17

     = 7x - 1

    = 7(11) - 1

    = 77 - 1

    = 76

Answers

Answer:

d) 1/5

Step-by-step explanation:

5(x + 1) - 8 = 5x(2-4)

5x+5-8 = 5x(-2)

5x-3=-10x

15x = 3

x = 1/5

Answer:

d. 1/5

Step-by-step explanation:

5(x + 1) - 8 = 5x(2-4)

=> 5x + 5 - 8 = 10x - 20x

=> 5x + 20x - 10x = 8 - 5

The greater of two numbers is 6 more than 4 times the smaller. Their sum is 41. FInd the numbers.

Answers

Answer:

7 and 34

Step-by-step explanation:

let x and y be the 2 numbers with x > y

The 2 equations to solve are

x = 4y + 6 → (1)

x + y = 41 → (2)

Substitute x = 4y + 6 into (2)

4y + 6 + y = 41 , that is

5y + 6 = 41 ( subtract 6 from both sides )

5y = 35 ( divide both sides by 5 )

y = 7

Substitute y = 7 into (1)

x = 4(7) + 6 = 28 + 6 = 34

The 2 numbers are 7 and 34

7 and 34 is the answer

A square sandbox has an area of 42ft to the power of 2. What is the approximate perimeter of the sandbox to the nearest hundredth?

Answers

Assuming I’m reading your question correctly, that the area is 42 square feet…

The length of each side is then sqrt(42) feet or about 6.480741 feet.

Since a square has four sides, you’d have 4*6.480741 for the perimeter, or about 25.922964 feet.

Rounding this to the hundredths place, you’d have 25.92 feet.
