To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos

abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be $R(x)=$ . Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

$R(x)=150+1.75x$

The problem tells us that we are driving 96 miles, so we can plug in 96 for $x$ and solve.

$R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318$

The total cost of the rental is going to $318.

Hope this helps!

What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

photoshop1234 [79]

Answer:

value of n = 2

Step-by-step explanation:

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}$

We need to solve the above equation.

Find Least Common multiplier from 5n, 5 = 5n

Multiply both sides of the equation by 5n

$\frac{4}{5n}*5n-\frac{1}{5}*5n=\frac{2}{5n}*5n\\Solving:\\4 -n = 2\\$

Now finding the value of n.

Adding -4 on both sides

$4 -n-4 = 2-4\\-n= -2$

Multiplying both sides by -1

n = 2

The value of n is 2.

We can verify by putting value of n in the given question.

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}\\n=2\\\frac{4}{5*2}-\frac{1}{5}=\frac{2}{5*2}\\\frac{4}{10}-\frac{1}{5}=\frac{2}{10}\\\frac{2}{5}-\frac{1}{5}=\frac{1}{5}\\\frac{2-1}{5}=\frac{1}{5}\\\frac{1}{5}=\frac{1}{5}$

So, value of n = 2

Find the lower quartile (Q1) median and upper quartile (Q3)of the data below

Tanzania [10]

Answer:

Below in bold.

Step-by-step explanation:

Arrange the data in ascending order:

1. 1 1 2 3 4 7 9

Median = middle number = 3.

Q1 = 1

Q3 = 7.

2. 26 31 34 38 42 66 74 78

Median = mean of 2 middle numbers = 40.

Q1 = 31.

Q3 = 74.

3. 36 45 49 52 53 64 81 87 93

Median = middle number = 53.

Q1 = 47.

Q3 = 84.
