Ben, Cam, and Justin are lumberjacks. The number of trees they chop down is given by b+2c+3j, where b is the number of hours Ben spends chopping, c is the number of hours Cam spends chopping, and j is the number of hours Justin spends chopping. How many trees do they chop down after Ben spends 8 hours chopping, Cam spends 3 hours chopping, and Justin spends 4 hours chopping?

Answers

Answer: There are 26 trees which they chop down .

Explanation:

Since we have given that

the number of trees they chop down is given by

b+2c+3j

Where 'b' denotes number of hours Ben spends chopping,

'c' denotes number of hours Cam spends chopping,

'j' denotes number of hours Justin spends chopping.

Now, we have also given that,

Number of hours Ben spends chopping = 8

Number of hours Cam spends chopping = 3

Number of hours Justin spends chopping = 4

Now, we put the value of all these variable in the above expression ,we'll get

8+2* 3+3* 4=8+6+12=26

Hence, there are 26 trees which they chop down .
Substitute the values into the equation...
b = 8 so 8+2c+3j
c = 3 if 8+2(3)+3j or 8+6+3j
j = 4 8+6+3(4) or 8+6+12
Add this all together and you get...
26 trees

Power bills usually show____. A)The total amount due
B$The kilowatt hours of electricity used
C)The payment due date
D)All of the above

Answers

D

Step-by-step explanation:

Based on the pricing per kilowatt energy set by the distributor/regulation in the jurisdiction, the due amount to be paid to the distributor may differ;

kW/h * price per kW = power bill

The power bill is also paid regularly such as monthly or annually and therefore will bear a due date.

Step-by-step explanation:

It contains the following

  • Total amount due; this includes your current amount due plus any outstanding balances and late payments
  • Due date; this is the date your payment is due
  • $The kilowatt hours of electricity used; the $Kilowatt hours measures amount of electricity which you have used in the past month

Therefore, the correct answer is "all of the above"

Kim and Courtney share a 16-ounce of box of cereal.  By the end of the week, Kim has eaten 3/8 of the box, and Courtney has eaten 1/4 of the box of cereal.  What fraction of the box is left?

Answers

³/₈

Further explanation

We will solve the problem of subtraction between fractions.

Given:

Kim and Courtney share a 16-ounce of the box of cereal.  

By the end of the week:

  • Kim has eaten ³/₈ of the box, and
  • Courtney has eaten ¹/₄ of the box of cereal.  

Question:

What fraction of the box is left?

The Process:

Kim has eaten ³/₈ of the box of cereal. Let's calculate how many fractions of the box are left after Kim has eaten them.

\boxed{ \ 1 - (3)/(8) = \ ? \ }

\boxed{ \ (8)/(8) - (3)/(8) = (5)/(8) \ }

Hence, the rest of the box after Kim has eaten ³/₈ of the box is

\boxed{\boxed{ \ (5)/(8) \ }}

Furthermore, Courtney has eaten ¹/₄ of the box of cereal. Let's calculate how many fractions of the box are left again after Courtney ate the remaining part since Kim had eaten it before.

\boxed{ \ (5)/(8) - (1)/(4) = \ ? \ }

Before we subtract, the denominator must be equated. Prepare ¹/₄ to be ²/₈. The numerator and denominator are multiplied by two.

\boxed{ \ (5)/(8) - (2)/(8) = (3)/(8) \ }

Thus, the fraction of the box left after Kim and Courtney have eaten is \boxed{\boxed{ \ (3)/(8) \ }}.\boxed{ \ The \ Answer \ }

- - - - - - - - - -

Quick Steps:

\boxed{ \ 1 - (3)/(8) - (1)/(4) = \ ? \ }

\boxed{ \ (8)/(8) - (3)/(8) - (2)/(8) = \boxed{ \ (3)/(8) \ } \ }

The summary scheme is as follows:

Initial conditions

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} \rightarrow \boxed{ \ one \ part = (8)/(8) \ }

Kim has eaten ³/₈ of the box: \boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\rightarrow \boxed{ \ (3)/(8) \ }

Courtney has eaten ¹/₄ (or ²/₈) of the box: \boxed{\cdot}\boxed{\cdot}\rightarrow \boxed{ \ (2)/(8) \ }

Final conditions

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} is subtracted by \boxed{\cdot}\boxed{\cdot}\boxed{\cdot} and is subtracted by \boxed{\cdot}\boxed{\cdot} equal \boxed{\cdot}\boxed{\cdot}\boxed{\cdot} as the remaining part \rightarrow \boxed{\boxed{ \ (3)/(8) \ }}

Solve p= 10a+3b for a.

Answers

Answer:

a = p/10 - (3 b)/10

Step-by-step explanation:

Solve for a:

p = 10 a + 3 b

p = 10 a + 3 b is equivalent to 10 a + 3 b = p:

10 a + 3 b = p

Subtract 3 b from both sides:

10 a = p - 3 b

Divide both sides by 10:

Answer: a = p/10 - (3 b)/10
