Answers

Answer 1
Answer:

Answer:  Brian sold 35 tickets.

Step-by-step explanation:  Given that Brian had 42 class fair tickets to sell and he sold (5)/(6) of the tickets.

We are to find the number of tickets that Brian sold.

We have

Total number of tickets that Brian had = 42.

Since he sold five-sixth of the total tickets that he had, so the number of tickets that Brian sold is given by

N_s=(5)/(6)* \textup{total number of tickets}=(5)/(6)*42=5*7=35.

Thus, Brian sold 35 tickets.

Answer 2
Answer: 35 becauses 7 times 5 = 35

Emily biked 9 miles in 3/4 hours . Which expression can she use to find her unit rate in miles per hour ?

Answers

Final answer:

Emily's unit rate in miles per hour can be found by using the expression 9 ÷ (3/4) or 9 x (4/3). When calculated, we find that Emily is biking at a rate of 12 miles per hour.

Explanation:

To find Emily's unit rate in miles per hour, we need to divide the total miles she biked by the time it took her in hours. In Emily's case, she biked 9 miles in 3/4 hours. So the expression she can use to find her unit rate in miles per hour is 9 ÷ (3/4). Dividing 9 by 3/4 is the same as multiplying 9 by the reciprocal of 3/4, which is 4/3. So, the expression can also be written as 9 x (4/3). If we calculate that, we get 12. So, Emily biked at a rate of 12 miles per hour.

Answer:

Hello there!

Divide 9 by 3 to get 3.

Then use that to multiply 3 by 4 to get 12.

Step-by-step explanation:

7 times as much as sum of 1/3 and 4/5

Answers

So the formula is
7*(1/3+1/5) = x

First find the common denominator of the fractions.  In this case the common denominator of 3 and 5 is 15 so we must convert them to 15ths.  To do that we divide 15 by the denominator and take that answer and multiply the numerator by it.

So for 1/3 we take 15/3(denominator) = 5 and multiply the numerator (1) by it

5 * 1 = 5 so 1/3 converts to 5/15

Do the same for 1/5 we take 15/5 = 3 and multiply the numerator (4) by it

3*4 = 12 so 4/5 converts to 12/15

Now we add 5/15 and 12/15 = 17/15 so we have our formula now to

7*17/15

We make seven a fraction 7/1 and multiply across 7*17 = 119 and 15 * 1 = 15

We have 119/15 which when we divide and get 7 14/15 as your answer
find a common denominator aka 15
so 5/15 and 12/15
= 17/15 times 7/1
119/15

Write an equation of the line that passes through (−4, −9) and is parallel to the line y=4x .

Answers

Answer:

y = 4x + 7

Step-by-step explanation:

parallel = same slope

y = 4x + b

plug in (-4, -9)

-9 = 4(-4) + b

-9 = -16 + b

b = 7

y = 4x + 7

Answer:

7=4x+7

Step-by-step explanation:

To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7
