Answer:

C. 5x + 11 = 36

Step-by-step explanation:

You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36

Answer:

5x + 11 = 36

Step-by-step explanation:

Looking at the tape diagram, if you count the x, you have 5x and then you have 11. So it would refer to as 5x + 11 and the total of the tape diagram is 36. So it would be :-

5x + 11 = 36

Solve using substitution. I know that the answer is (1,1), but I have to show my work and I forgot how to do it.

Answers

If y = -x + 2, then substituting this into the first equation lets you solve for x :

x + 4y = 5

x + 4 (-x + 2) = 5

x - 4x + 8 = 5

-3x = -3

x = 1

Now solve for y :

y = -x + 2 = -1 + 2 = 1

So the solution is indeed (x, y ) = (1, 1).

Jax takes a bus from Washington DC to New York City. The trip takes 5 hrs. and 47 minutes. He arrives in New York City at 1:58 pm. what time did the bus leave Washington DC?

Answers

Answer:

8:11 a.m.

Step-by-step explanation:

We need top subtract 5:47 from 1:58 pm.

Since we cannot subtract 5 from 1, we add 12 to the 1:58 hours digit.

1 + 12 = 13

1 pm is 13 hours of the day.

13:58 - 5:47 = 8:11

Answer: 8:11 a.m.

Answer:

16 bicycles and 21 tricycles

Step-by-step explanation:Both bicycles and tricycles have 1 set of handlebars. Bicycles have 2 wheels while tricycles have 3.

Using this information, set up a system of equations, where b is the number of bicycles and t is the number of tricycles:

b + t = 37

2b + 3t = 95

Solve by elimination by multiplying the top equation by -2:

-2b - 2t = -74

2b + 3t = 95

t = 21

Then, plug in 21 as t into one of the equations:

b + t = 37

b + 21 = 37

b = 16

So, there are 16 bicycles and 21 tricycles

The ending balance of each account receivable is aged on the basis of three time periods as follows: (1) not yet due, $13,000; (2) up to 120 days past due, $6,000; and (3) more than 120 days past due, $5,500. Experience has shown that for each age group, the average loss rate on the amount of the receivables at year-end due to uncollectibility is (1) 2 percent, (2) 12 percent, and (3) 30 percent, respectively. At December 31 (end of the current year), the Allowance for Doubtful Accounts balance is $710 (credit) before the end-of-period adjusting entry is made. Data during the current year follow: a. During December, an Account Receivable (Patty's Bake Shop) of $660 from a prior sale was determined to be uncollectible; therefore, it was written off immediately as a bad debt. b. On December 31, the appropriate adjusting entry for the year was recorded. Required: 1. Give the required journal entries for the two items listed above. 2. Show how the amounts related to Accounts Receivable and Bad Debt Expense would be reported on the income statement and balance sheet for the current year. Disregard income tax considerations.
