The difference of a number and eight is equal to 14.

Answers

"A number" means the unknown.

"Difference" means to subtract.

We already know two numbers, 8 and 14, but we don't know "A number."

We can put v as our variable. You can put any type of letter.

Therefore, the answer is: v - 8 = 14

a typical tip in a restaurant is 18% of the bill. If the bill is 150,what would the typical tip be​

Answers

You want to leave a 18% tip on a meal that cost $150.

First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.

Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or

0.18 x $150.00=$27.00.

So, the amount of tip you are going to leave is $27.00.

This makes the total cost of your meal (to write on your charge slip or other payment)

$150.00 + $27.00 = $177.00.

A lift driver charges $5.25 for the first mile of the trip and$1.25 each mile after that. He charges the customer $24 for the ride.

Answers

Answer: 15 miles

Step-by-step explanation:

The equation is 5.25+1.25x=24 where x is each additional mile so to solve for x it would be  1.25x=18.75 and divide both sides to solve for x

yeah what they said ^

What is the value of y if 525=y5?

Answers

Answer:I think its 105

Step-by-step explanation:  525=y5 ... you divide by 5 on both sides and 525 divided by 5 equals 105. So then you bring then y down and y=105.

The amount paid for different weights of oranges at a farmer’s market are shown below.

Answers

The answer is 8lbs because 3/2 is 1.5 and 12/1.5 is 8

Answer:

8

Step-by-step explanation:

Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.

So:

$3.00 / 2 = $1.50

So now we have :

1 pound of oranges = $1.50

With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).

Like so:

$12.00 / $1.50

=

8

We can check this by inputting the 8 on the ?

If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.

Hope this helps!

if p(a)=0.24 and p(b)=0.52 and a and b are independent, what is p(a or b)?

Answers

Download the app photo math and there is the answer

The probability of P(a or b) is 0.1248

Given the following probabilities

P(a) = 0.24

P(b) = 0.52

Independent events mean that each event can occur at different times.

P(a or b) = P(a) * P(b)

Substitute the given parameters into the formula;

P(a or b) = 0.24 * 0.52

P(a or b) = 0.1248

Hence the probability of P(a or b) is 0.1248
