Answer:

Prancer spent 240$

Dasher spent 120$

Cupid spent 360$

Step-by-step explanation:

Dasher = D

Prancer = P

Cupid = C

"Dasher spent half as much as Prancer"

D = 1/2P

"Cupid spent 3 times more than Dasher"

C = 3 * D

C = 3 * 1/2P

P + c + d = 720

P + 1/2p + 3*1/2P = 720

3P = 720

3P/3 = 720/3

P = 720/3

P = 240

Prancer spent 240$

Dasher spent 120$ (240/2)

Cupid spent 360$ (120*3)

Answer:

Dasher spent $120, Prancer spent $240, and Cupid spent $360

Answer:

64.8 in

Step-by-step explanation:

The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation  324=5x. Divide both sides by five gets us 64.8 = x.

To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.

Answer:

x=26/3

Step-by-step explanation:

3x-10=16

add 10 to both sides

3x=16+10

simplify

3x=26

divide both sides by 3

x=26/3

Answer:

17) 3   18) 3

Step-by-step explanation:

Answer:

17. C

18. C

Step-by-step explanation:

The greater the negative number, the less the number values. -10 is smaller than -8 because -10 is farther away from the number line to the left.

Go in terms of the tenths place. If its smaller than the number will be less than the bigger numbers. 0.227 is bigger than 0.18 because it has a 2 in the tenths place.

Answer:

6 units to the right

Step-by-step explanation:

i added it to a graph.

Answer: You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:

R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

Step-by-step explanation:

Answer:

x=-8

Step-by-step explanation:

y=8 is a horizontal line crossing the y-axis at 8

A line perpendicular to this would be a vertical line crossing the x-axis at -8

Answer:

75°

Step-by-step explanation:

We can assume that the angle shown and an angle that measures 15° makes a complementary angle. A complementary angles is when two angles add up to be 90°. We can create an equation and simplify:

15 + x = 90

x = 75

Answer:

The answer would be -2 1/6

Step-by-step explanation:

The arrow goes to the left side because it is negative. -1/3 would be equal to -2/6. -5/6 + -1/6 + -1/6 = -1 1/6. Add the 1 and you get -2 1/6!

The reciprocal of 7 is 1/7.

The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.

Given:

The number is 7.

Let n be the reciprocal of 7.

If n is a real number, then 1/n will be n's reciprocal.

To find the reciprocal of 7:

We need the value that can give us 1 when multiplied by 7.

That means,

n x 7 = 1

Divide by 7 to both sides,

n = 1/7

Therefore, the reciprocal is 1/7.

Answer:

A) x = -1/4

Step-by-step explanation:

There are 4 x's, 4 1's on one side of the equation, and 3 1's on the other side

4x + 4 = 3

Subtract 4 on both sides

4x = -1

Divide each side by 4

x = -1/4
