Divide by 24 each side

x < 2

-2x - 2 < 8

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?

Answers

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120

Answer

120km

Step-by-step explanation:

let s = the original speed

Write a distance equation; dist = time * speed

3(s-10) = 2(s+10)

3s - 30 = 2s + 20

3s - 2s = 20 + 30

s = 50 km/hr is the original speed

confirm this, find the distances

3(50-10) = 120 km

2(50+10) = 120 km

95 inches is shorter

Answer: 95 in is shorter

Step-by-step explanation:

there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft

How many 1/8 tps can go into 1/8 cup?

Answers

Answer:

6 tps

Step-by-step explanation:

3 tsp = 1 tablespoons

16 table spoons = 1 cup

therefore 48 teaspoons = 1 cup

therefore 1/8th cup =6 teaspoons

Answer:

(1/8) cup = 6 U. S. teaspoons

Step-by-step explanation:

Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.

We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:

(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.

N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?

Answers

When the point N is dilated, the coordinate of N changes to N'

The coordinate of point N is (8,12)

How to determine the coordinate of N

The given parameters are:

N' = (10,15)

k = 5/4

To calculate the coordinate of N, we make use of:

N * k = N'

So, we have:

N * 5/4 = (10,15)

Multiply both sides by 4

N * 5 = (40,60)

Divide both sides by 5

N = (8,12)

Hence, the coordinate of point N is (8,12)

State your position, and support it with your reasoning and evidence cited from reading the article below.Celebrity accessories top the list when it comes to peculiar auction purchases. Of course, most are more solid than air. Fans went gaga when a fake fingernail worn by Lady Gaga herself made its way to auction. And a jaw-dropping chunk of change was once plunked down for a chomped-up piece of Britney Spears's chewing gum. When it comes to unusual investments, are humans just "born this way"?According to experts, the answer is yes! "The earliest archeological records show that ownership of objects is a universal phenomenon that has existed across time, cultures, and people," Professor Kiara Timpano told the University of Miami press. And what might be considered one person's trash is often someone else's treasure. Like a tennis racket smashed up by queen of swing, Serena Williams.So why do people collect such offbeat objects? It depends on the person. Some bidders raid their piggy banks for sentimental reasons. After all, nothing brings back feelings of childhood quite like an original pair of Dorothy's ruby slippers. Others drop great gobs of dough on items that are mostly for show. Or they may want to get hold of items that gain value over time. Like what? Like any pair of game-worn Air Jordans that adorned basketball legend Michael Jordan's famous, though sweaty, feet.Then there's the thrill of the hunt. Scientific research suggests that finding and acquiring items believed to be of value stimulates the brain and leads to feelings of pride and satisfaction.But shopping for strange stuff isn't always about self-fulfillment. It's sometimes about helping others. A teacup stained with Lady Gaga's lipstick, for instance, raised funds to support Japanese art students affected by a terrible tsunami and earthquake. Singer Justin Bieber once lopped off his locks for the auction block. Proceeds from the sale of his trimmed tresses went to help a pet shelter. Then there's Marvel star Scarlett Johansson. She spread some love, and possibly a cold, by putting one of her used tissues on eBay to raise money for a food bank.From the irregular to the icky, you can find some outrageous items at auction.
