Adam can travel \boxed{{\mathbf{168 km}}}  with 14{\text{liters}}  of fuel.

Further explanation:

The direct relationship is the relationship between two variables in which one variable increases then the other variable also increases and vice versa. It is also known as the positive relationship.

The examples of the direct relationship is the supply function and speed distance function.

The direct relationship of the variables x{\text{ and }}y  as

 \frac{{{x_1}}}{{{x_2}}}=\frac{{{y_1}}}{{{y_2}}}                                                                                                         ….. (1)

Here, {x_1},{x_2}  are the quantities of the variable x  and {y_1},{y_2}  are the quantities of the variable  y

Given:

Adam travelled the distance 132{\text{km}}  with 11 liters of fuel.

Step by step explanation:

Step 1:

The given data can be represented in the table form as,

It can be observed that the data is direct relationship.

Here, {x_1}=132,{x_2}=x,{y_1}=11{\text{ and }}{y_2}=14

Step 2:

Now substitute the value {x_1}=132,{x_2}=x,{y_1}=11{\text{ and }}{y_2}=14  in equation (1) to obtain the value of x .

\begin{gathered}\frac{{{x_1}}}{{{x_2}}}=\frac{{{y_1}}}{{{y_2}}}\hfill\\\frac{{132}}{x}=\frac{{11}}{{14}}\hfill\\\end{gathered}

Now solve the above equation by the cross multiplication method.

\begin{aligned}\frac{{132}}{x}&=\frac{{11}}{{14}}\\132\times14&=11x\\1848&=11x\\x&=168\\\end{aligned}

Therefore, the value of x=168 .

Thus, Adam can travel 168{\text{ km}}  with 14{\text{liters}}  of fuel.

Samantha divides $16,000 into three investments: a savings account 3 points paying 7% annual interest, a bond paying 9%, and a m
kipiarov [429]

Answer:

2000 was the amount of the investment in the savings account

6000 was the amount of the investment in the payment of bonds

8000 was the amount of the investment in the money market

Step-by-step explanation:

In this case, a system of equations must be generated with the information given in the statement.

Let x be the amount of the investment in the savings account

Let y be the amount of the investment in the payment of bonds

Let z be the amount of investment in the money market

Now, the first equation would be that of total investment:

x + y + z = 16000

The second equation is that of interest:

0.07 * x + 0.09 * y + 0.12 * z = 1640

Last, her equation has invested three times more in the bond payment than in the savings account:

3 * x = y

So we have 3 equation with 3 unknowns. Therefore there is a solution.

x + y + z = 16000

0.07 * x + 0.09 * y + 0.12 * z = 1640

3 * x = y

In order not to make the answer too extensive, we will solve the system of equations with the help of symbolab, here is the step-by-step of everything they do in a very detailed and precise way.

https://es.symbolab.com/solver/step-by-step/x%20%2B%20y%20%2B%20z%20%3D%2016000%3B%200.07%20%5Ccdot%20x%20%2B%200.09%20%5Ccdot%20y%20%2B%200.12%20%5Ccdot%20z%20%3D%201640%3B%203%20%5Ccdot%20x%20%3D%20y

From this, the results are as follows:

x = 2000

y = 6000

z = 8000

Thus

2000 was the amount of the investment in the savings account

6000 was the amount of the investment in the payment of bonds

8000 was the amount of the investment in the money market

Re-solve please.<br><br> 2 5/6 + (-1 4/12) =
elena-s [515]

Answer:

1.5 as decimal, 1 1/2 as a fraction

Step-by-step explanation:

1. convert 2 5/6 & (-1 4/12) to a improper fraction.

17/6 and  -16/12

2. multiply 17/6 by 2 to match -16/12's denominator

17/6 * 2 = 34/12

We now have

34/12 + -16/12

A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.

We have:

\frac{34}{12}-\frac{16}{12}

Now solve. 34-16 = 18

our answer is 18/12
