Abe has some nickels and some pennies. If the pennies were nickels and the nickels were pennies, he would have 80 cents less than he has now. The difference between the number of nickels and the number of pennies that he has

A) Is 12

B) Is 20

C) Is 24

D) Is 28

E) Cannot be Determined

Answers

Answer 1

Answer:

B) Is 20

Step-by-step explanation:

Let X represent the number of pennies.

Let Y represent the number of nickels.

We know that X + 5Y = (Y + 5X) + 80.

4Y = 4X + 80

Y = X + 20

Hence, the difference between the number of pennies and the number of nickels is 20.

The terminal side of Ø is in quadrant IV and cos Ø + 5/13, what is sin Ø?

A. -5/12
B. -12/13
C. 12/13
D. 5/12

Answers

Answer:

It’s -12/13

Step-by-step explanation:

The value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

What is the trigonometric ratio?

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

We have:

The terminal side of Ø is in quadrant IV quadrant

cosØ = 5/13

sin²Ø = 1 - cos²Ø

sin²Ø  = 1 - (5/13)²

sinØ = √(144/169)

sinØ = -12/13 (negative in IV)

Thus, the value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

a hotel at your vacation destination quotes you a rate of $200/night. you find a similar hotel in town for 25 percent less. if you select the less expensive hotel, how much will you pay for a three-night stay?

Answers

Answer: $450

Step-by-step explanation:

Since the similar hotel in town goes for 25 percent less, that means that (100.- 25) = 75% would be paid. This will be:

= 75% × $200.

= 75/100 × $200.

= $150

The amount paid for a three-night stay will be:

= $150 × 3

= $450

Point V lies between points U and W on Line segment U W.
If UW = 9x – 9, what is UW in units?

Answers

Answer:

See Below

Step-by-step explanation:

2x - 4 + 4x + 10 = 9x - 9

6x + 6 = 9x - 9

3x = 15  

x = 5  

UW = 9x-9 = 9*5-9  

UW = 36 units

Answer:

36

Step-by-step explanation:

UW = UV + VW

9x - 9 = 2x - 4 + 4x + 10

9x - 2x - 4x = -4 + 10 + 9

3x = 15

x = 5

UW = 9x - 9 = 9(5) - 9 = 45 - 9 = 36

The slope is -7/4.
To find the slope you can first subtract the two ys. and get -7. Because the y is negative it means the slope will be negative. You can then subtract the xs and get -4. You can make a fraction from these two numbers, always putting the y on top, and the x on the bottom.

Answer:

(12) The perimeter of the four shaped figure is 12x - 10

(13) The perimeter of the rectangle is 18x + 10

(14) The perimeter of the hexagon is 24x

Step-by-step explanation:

(12) The perimeter of the four shaped figure is calculated as;

P = (x )  +   (3x + 2)    +  (6x - 17)   +  (2x + 5)

Collect like terms together, in order to simplify the expression

P = (x + 3x + 6x + 2x) + (2 - 17 + 5)

P = 12x - 10

(13) The perimeter of the rectangle is calculated as;

P = 2( L + B)

P = 2L + 2B

Where;

L is length of the rectangle

B is the breadth of the rectangle

P = 2 (6x + 5) + 2(3x)

P = 12x + 10  + 6x

P = 18x + 10

(14) The perimeter of the hexagon is calculated as;

P = 6L

Where;

L is length of each side

P = 6 (4x)

P = 24x

-6x + 5 = 17
What’s the answer

Answers

Answer:

x = -2

Step-by-step explanation:

-6x + 5 = 17

First, combine the constants by subtracting 5 from each side.

-6x = 17 - 5

-6x = 12

Now you want x by itself, so divide both sides by -6.

x = -2

Check your answer by plugging x = -2 into the original equation.

-6(-2) + 5 = 17

12 + 5 = 17

17 = 17

Your answer is correct.

Answer:

-2

Step-by-step explanation:

-6x + 5 = 17

-6x = 17 - 5

-6x = 12

-6x = 12
