Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Answers

Answer 1

Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.

Answer 2

Answer:no

Step-by-step explanation:

Because u can not subtract a denominator from numerator u must subtract the denominator by the denominator

Answer: 1:2

Step-by-step explanation: you have to subtract 80 from 120 to get 40. Then you would have the ratio 40:80. Then when you simplify it would be 1:2.

The visual work:

120-80=40

40:80=1:2

i know u didnt need the explanation and all that but just wanted to show you how i got it- lol

Answer:

Answer down below!

Step-by-step explanation:

If there were 80 blue marbles, but the amount of red marbles isn't stated. First, you need to figure out how many there are. 80 + Number = 120

Number = 40

The ratio is 80:40

Cutting that in half would be 40:20

We're getting closer

20:10

This is starting to get pretty obvious what our answer could be!

If we kept cutting we would get 2:1

Your answer is 2:1!!

Oliver is starting a running plan to train for a race. In the first week of his running
plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage
by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be
expected to run during his oth week of the training plan?

Answers

Answer:

Step-by-step explanation:

He starts at 14 miles and will add 3.5 miles to it every week. You are checking how many miles he will run by the 10th week so you would do 3.5 x 10 which equals 35 then add that to 14 to get your total of 49 miles. Have a good day lol

Step-by-step explanation:

Variables are letters used in math so you were correct.

Coefficients are numbers with a variable. So to find the coefficient you would look for a number "connected" to a variable. This would be -2 because it is being subtracted from the first term.

The constant is 3/7 because you could put it on a number line.

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)

the answer is $460.20

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b + 2m. Which expression is equivalent to 4b + 2m?

Answers

Answer:

2(2b + m)

Step-by-step explanation:

We can simplify the expression given in the question using factoring:

4b + 2m

(2 x 2)b + (2 x 1)m

2(2b + m)

The equivalent expression is 2(2b + m).

What is meant by an expression?

It is a sentence with a minimum of two numbers or variables and at least one math operation.

Given that b is the number of books and m is the number of magazines.

The cost of a book = $4

The cost of a magazine = $2

The given expression for Tatianan's total purchase is 4b + 2m.

The given expression can be simplified as

4b+2m = 2(2b+m)

Hence, 2(2b+m) is the equivalent expression of 4b+2m.
