D is the correct answer partly because it's the only equation that has the correct outcome and partly because you have to divide 1313 by 4 anyways for the answer to make sense.
number of cups you have ÷ number of cups per serving = number of servings

What is 3/2n-8/3=29/12
bixtya [17]

Simplify 3/2n to 3n/2

3n/2 - 8/3 = 29/12

Add 8/3 to both sides

3n/2 = 29/12 + 8/3

Simplify 29/12 + 8/3 to 61/12

3n/2 = 61/12

Multiply both sides by 2

3n = 61/12 × 2

Simplify 61/12 × 2 to 122/12

3n = 61/6

Divide both sides by 3

n = 61/6/3

Simplify 61/6/3 to 61/6 × 3

n = 61/6 × 3

Simplify 6 × 3 to 18

<u>n = 61/18</u>

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150

Multiply both sides by 100.

7x+16x+27x=15000

50x=15000

Divide both sides by 50.

x=\dfrac{15000}{50}

x=300

The amount invested at 7% is 300.

The amount invested at 8% is

2(300)=600

The amount invested at 9% is

3(300)=900

Thus, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Given f(x)=-2x-1, solve for x when f(x)=-7
Svetlanka [38]

Answer:

The answer is -15.

Step-by-step explanation:

1. 2x - 1

2. 2(-7) - 1

3. (-14) - 1

4. -15

By plugging in our x value, we are able to use PEMDAS to  multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.
