Evaluate the expression for d = 4, f = –3, and g = –12.

fg − d + f = ?

Answers

Answer 1

d= fgf+g-F

Step-by-step explanation:

F = fg f + g - d  solve the equation for d

Solve for d means we need to get 'd' alone

To get 'd' alone we need to move all the remaining terms to the other  side

F = fg f + g - d

First we subtract fgf on both sides

F - fg f = g - d

Now we subtract g on both sides

F - fg f - g = - d

now divide all the term by -1, so sign changes for all terms

-F + fgf +g = d

so d= fgf+g-F

You need 112 K-cups for a party. A box of K-cups costs $16 for 36 K-cups. What is the minimum amount of money you will spend?

Answers

Answer:

$49.60

Step-by-step explanation:

The equation setup I used for this was as follows: $16 x (112/36)

Using PEMDAS, you'd start with the division part, 112/36. Although, I did this a bit differently, and being a bit further in school, I don't know if you go through this where you're at.

Start by factoring 112 into 4(28). This leaves you with 4(28)/36.

Next, cancel 4 out of 36. Since 4 is the common factor in 28 and 36, you cancel the four out of the equation, leaving you with 28/9. Convert this to its decimal form, 3.1.

Finally, take the 3.1 and multiply that by $16, which comes out to $49.60.

Answers

Answer:

15 Rolls.

Step-by-step explanation:

This problem is one that can be solved simply by dividing.

Take 5, and divide that by 1/3.

However, you can't just do this. The way I did it was by turning 5 into 5/1. Then, Multiply by the reciprocal, which would be 5 x 3, which equals 15.

Well, we first have to find out what the diagram says.

So what the diagram says is that  18 + 18 + 18 = 54.

Given this information,  we have to figure what other answers = 54.

Therefore the answers are

Answers

Answer:

1) 2 boots for 7 shoes = 8 boots for 7x4 shoes (28 shoes)

2) 7 shoes for 2 boots = 49 shoes for 2x7 boots (14 boots)

Answer:

1. 28

2. 14

Step-by-step explanation:

1. As you can see on the bottom 2x4=8 (or 8 divided by 2) so all they did was multilpy the first number by four so to get the second number on the top you have to do the same thing (7x4=28)

2. Now that you have the second number on the top you can find the third number on the bottom. So all you have to do is divide 49 by 28 which is 1.75, then you would go down to the bottom and do 8 times 1.75 and you get 14

Trevor is having trouble understanding how the degree of a nonzero constant is 0. Use the expression 3x^0 to help explain this concept to Trevor.

A. The degree of a monomial is the sum of the number of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.
B. The degree of a monomial is the coefficient of its variable. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Since the expression has no variables, the degree of the nonzero constant 3 is 0.
C. The degree of a monomial is always zero. Therefore, the degree of the nonzero constant 3 is 0.
D. The degree of a monomial is the sum of the exponents of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?

Answers

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
