Answer:

“A.”

Step-by-step explanation:

15 + 3x is the equation, so we need to have the 3 multiplying by “x” no matter what.

Answer “A.” 3(5+x) would give us 15+3x when the 3 is distributed to the 5 and the “x”

You are welcome :D

Answer:

[A] 3(5+x)

Step-by-step explanation:

To Find which expression is equivalent to 15 + 3x

We can simplify to see:

Start with [A] 3 ( 5 + x )

3 · x = 3x

3 · 5 = 15

3x + 15

True

Next we have [B] 5 ( 3 + x)

5 · x = 5x

5 · 3 = 15

5x + 15

False

Then we have [C] 3 ( 5 + 3x)

3 · 3x = 9x

3 · 5 = 15

9x + 15

False

Finally, we have [D] 5 ( 3 + 3x)

5 · 3x = 15x

5 · 3 = 15

15x + 15

False

3x+15 is the same thing as in 15 + 3x

Thus, [A] 3 ( 5 + x) is the correct answer.

Gordon got a mountain bike for his birthday. when he took the bike out for a ride he biked 3/4 of a mile in 1/10 of an hour , at this rate how far would Gordon bike in 2 hours?

answer is needed asap
​

Answers

Answer: 7. 2/4

Step-by-step explanation:

3/4. Divided by 1/10

The distance that Gordon would bike is 15 miles.

What is the distance that Gordon would bike?

The first step is to determine the average speed of the mountain bike. Average speed is how fast an object moves with respect to time.

Average speed = total distance / time

3/4 ÷ 1/10

3/4 x 10 = [tex]\frac{30}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]

The formula to determine the distance he would cover given his speed is

Distance = average speed x time

7[tex]\frac{1}{2}[/tex] x 2

[tex]\frac{15}{2}[/tex] x 2 = 15 miles

Answers

Answer:

You would have a horizantal line with a y-intercept of 1.

Step-by-step explanation:

Answer: y is less than or equal to 1

Step-by-step explanation:

Whenever you see parentheses you should automatically think of P.E.M.D.A.S.

Step 1:

In order to get rid of the parentheses you will have to combine like terms, meaning that the 7 will need to be multiplied by whats inside the parentheses.

7 x y = 7y

7 x 2 = 14

Rewritten, your equation should look like this: 7y + 14 - 6 less than or equal to 15

Step 2:

Next, we need to get rid of the 6 which means that 6 should be added in order to cancel it out. 6 should also be added to the other side of the equation.

-6 + 6 = 0

15 + 6 = 21

Rewritten, your equation should look like this: 7y + 14 less than or equal to 21

Step 3:

In order to further balance out the equation, you will need to subtract the 14 from both sides of the equation.

14 - 14 = 0

21 - 14 = 7

Rewritten, your equation should look like this: 7y is less than or equal to 7

Step 4:

Finally, you should divide both sides by seven!

7y/7 = y

7/7 = 1

Rewritten, your equation should look like this: y is less than or equal to 1

I hope this helps!

This table represents Una's check register. Her checking account had a balance of $1,568.45 on January 18. Use the information in the check register to determine the balance of Una's checking account after the transaction on February 7.

Answers

Answer:

$1187.22

Step-by-step explanation:

The balance was $1568.45 on 1/18 then she decided to withdraw $765.23 on 1/30, so we subtract 765.23 from 1568.45 which is 803.22 but then she added $384 to the account on 2/7 so we add 384+803.22 which equals to $1187.22, which would be the total balance on her account.

Answer:

$1,187.22

Step-by-step explanation:

After all of the Transactions, she will end up with $1,187.22

$1,568.45-$765.23= 803.22

$803.22+384=$1,187.22

Answer: $1,187.22
