The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.

Write an expression to model this situation.
How far could you travel if you drove 40 miles?

Answers

Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)

Step-by-step explanation:

The equation for these types of problems is y = mx + b.

M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.

Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.

If you plug everything in, you would get y= $0.20x + $35.

I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.

Now that we know x would be the amount of miles, we can plug that into the equation.

You would get y= $0.20 * 40 + $35.

Sorry, I’m not that good at explaining, but I hoped this helped!

y= .20x + 35

It would cost $43 to travel 40 miles

Evaluate if x=5 x^2+10

Answers

Answer:

[tex]35[/tex]

Step-by-step explanation:

To evaluate the expression:

[tex]x^2+10[/tex]

First, consider the given information:

[tex]x=5[/tex]

Substitute the given value of [tex]x[/tex] into the expression:

[tex]5^2+10[/tex]

(Note that [tex]5^2[/tex] is the same as [tex]5*5[/tex])

[tex]5*5=25[/tex]

[tex]5^2=25[/tex]

Add:

[tex]25+10=[/tex]

[tex]35[/tex]

-

We can check our work by setting our solution equal to the initial expression:

[tex]x^2+10=35[/tex]

Substitute [tex]x[/tex] for its given value:

[tex]5^2+10=35[/tex]

Simplify [tex]5^2[/tex]:

[tex]25+10=35[/tex]

Add:

[tex]35=35[/tex]

Since both sides of the equation are equal, our solution is correct!

Answer:

35

Step-by-step explanation:

Because X=5, the equation is literally just asking 5x5=10. So, following the order of operations, I would do 5x5 first which equals 25 plus 10. Since 25+10=35.  The answer is 35. Hope this helps! :p

Jack counted 3 pink rose bushes to every 8 yellow rose bushes. Later in the year, there was a drought and many rose bushes died. New rose bushes were planted to make sure there were the same number of rose bushes before the drought. The new ratio of the number of pink rose bushes to the number of yellow rose bushes is 5:6. After planting new yellow rose bushes there were 180 yellow rose bushes. How many pink and yellow rose bushes were there before the drought? Explain your answer using a tape diagram."

Answers

67.5 pink 180 yellow

The ratio at the beginning of the year was 3:8 then it became 5:6 it says that they planted the rose bushes so there would be the same number as before so that means the ratio was 3:8 with 180 yellow rose bushes, to start solving you have to find out how many yellow rose bushes were represented by a 1 in the ratio, to get that divide 180 by 8 to get 22.5, now you know that a 1 in the ratio is equal to 22.5 bushes, multiply 22.5 by 8 to get the total number of yellow bushes and multiply it by 3 to get the total number of pink bushes so then you get (obviously) 180 total yellow rose bushes and 67.5 total pink rose bushes before the drought, you can check that by simplifying the ratio of 67.5:180 which simplifies into 3:8 which means the numbers check out!

Josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester. She wants to know what she needs to earn on the last test to maintain her grade. Rearrange the following equation for b, where C is the average of 2 test scores, a and b. C=a+b/2
Please DO NOT say that this has already been answered, the answer options were different than this question.
Options:
a.) b = 2C/a
b.) b = 2C + a
c.) b = 2C - a
d.) b = 2C(a)

Answers

It it b that is the answer

The equation C=a+b/2 can be rearranged for b as b=2C - a. Therefore, option C is the correct answer.

We need to rearrange an equation C=a+b/2 for b, where C is the average of 2 test scores, a and b.

What is an average?

By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.

The equation C=a+b/2 can be rearranged for b as follows:

Now, C=a+b/2

⇒2C=a+b

⇒b=2C - a

The equation C=a+b/2 can be rearranged for b as b=2C - a. Therefore, option C is the correct answer.
