x = 2 is the right answer.i just need this last question Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $49.96 and costs an additional $0.15 per mile driven. The second plan has an initial fee of $57.96 and costs an additional $0.13 per mile driven. How many miles would Milan need to drive for the two plans to cost the same?
Answer:
400 miles
Step-by-step explanation:
Let the total cost of a plan be $T and the number of miles driven be m.
First plan
T= 0.15m +49.96 -----(1)
Second plan
T= 0.13m +57.96 -----(2)
When the two plans cost the same, the value of T in the first plan is equal to that of the second plan.
Equating (1) and (2) together:
0.15m +49.96= 0.13m +57.96
0.15m -0.13m= 57.96 -49.96
0.02m= 8
m= 8 ÷0.02
m= 400
∴ Milan would need to drive 400 miles for the two plans to cost the same.
the sum of two numbers is -90. Their difference is 16. Find the numbers

The numbers are 53 and 37
Step-by-step explanation:
You use a total of 11 base 10 blocks to show this number the number.the number of one blocks is greater than the number of 10 blocks.
Answer:
give me the brainliest
Step-by-step explanation:
Let x is the ones digit
Let y is the tens digit
Given that:
You use a total of 15 base ten blocks to show this number:
<=> x + y = 15 (1)
One of the digits is 6, so substitute into (1) we have another digit equals to: 9
Because the number of ones block is greater than the number of ten blocks
<=> y > x
<=> y = 9 and x= 6
So that number is: 69.

Answer:
m = -3/2
Step-by-step explanation:
Given the following points on the graph, (0, 9) and (2, 6):
Let (x₁, y₁) = (0, 9)
(x₂, y₂) = (2, 6)
Plug these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 9)/ (2 - 0)
m = -3/2
Therefore, the slope of the graph is -3/2. It has a negative value (hence, a negative slope) because the line is declining from the left side of the graph towards the right.

Step-by-step explanation:
Suppose that you could replace the ordered pair (1, 4) to make the relation R (shown left) into a function. Which ordered pair would work? (1, 2) (â€"1, 4) (2, 3) (4, 15).
We want to see which ordered pair we can add to the one we have in order to make R a function (sadly, we do not have the relation R, so expect a general answer).
Let's start by defining a function.
A function is a relation that maps elements from one set, the domain, into elements of another set, the range.
Where we also have a rule, each element in the domain can be mapped into only one element in the range.
So for example, if our relationship is:
R { (1, 2), (1, 3), (2, 4)}
The element of the domain "1" is being mapped into two different elements of the range, then this is not a function.
So, to answer the question, you would want to replace the element (1, 4) from one element that does not share the first value with any other of the relation.
Just to given an example, if the relation is:
R : { (1, 1), (1, 4), (2, 3), (3, 6)}
From the options, the only one that does not share the first element with any of the ordered pairs in R is (4, 15)
Then we replace (1, 4) by (4, 15)
And the relation becomes:
R' : {(1, 1), (2, 3), (3, 6), (4, 15)}
Which is a function.

At a local garden shop, the price of plants includes sales tax. The cost of 4 large plants and 8 medium plants is $40. The cost of 5 large plants and 2 medium plants is $28. If l is the cost of a large plant and m is the cost of a medium plant, write a system of equations that models this situation.
Answer:
4L + 8 m = $40
5L + 2m = $28
Step-by-step explanation:
L = cost of a large plant
m = cost of a medium plant
4L + 8 m = $40
5L + 2m = $28
System of Equations : 8 M + 5 L = 40 ; 5 M + 2 L = 28
Given : Cost of 4 large plants 'L' & 8 medium plants 'M' = 40
Cost of 5 large plants 'L' & 2 medium plants 'M' = 28
So, as per total cost, the equations are :
8 M + 5 L = 40 5 M + 2 L = 28To learn more, refer https://brainly.com/question/23589883?referrer=searchResults

-2/3x +2y=-7 in slope intercept form
Answer:
y = (1/3)x - 7/2
Step-by-step explanation:
Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
Lets transform this equation into that form using algebra rules.
-2/3x +2y = -7
get y alone
2y = (2/3)x - 7
divide everything by 2
y = (2/6)x - 7/2
simplify
y = (1/3)x - 7/2

Rosa put an “blank” cream on the cut on her finger to keep germs out of it
1- interlocking
2-antimedicine
3-antiseptic
4- interrelated
Rosa put an antiseptic cream on the cut on her finger to keep germs out of it.
An antiseptic is a substance that prevents the growth and development of microorganisms, such as bacteria, on living tissues.
When Rosa applied antiseptic cream to her cut finger, she aimed to create an environment hostile to germs. This action helps prevent infections and promotes the healing process.
The term antiseptic is derived from the Greek words "anti," meaning against, and septikos, meaning putrefying. Antiseptics are commonly used for cleaning wounds, disinfecting surfaces, and maintaining personal hygiene. They are milder than disinfectants, which are typically used on inanimate objects.
Rosa's choice of an antiseptic cream demonstrates her understanding of the importance of wound care. The cream likely contained substances that inhibit bacterial growth, such as hydrogen peroxide or iodine. By applying the antiseptic cream, Rosa effectively created a barrier against potential infections. It's crucial to clean and treat cuts promptly, as untreated wounds can lead to more severe health issues.
In summary, the use of an antiseptic cream by Rosa showcases her responsible approach to wound care. Antiseptics play a vital role in preventing infections and supporting the body's natural healing process. By applying an antiseptic cream, Rosa took a proactive step in safeguarding her health and ensuring the well-being of her injured finger.

A plane flew at a constant speed between Denver and

1-3) Complete the table.
Time (Hours)
Distance (Miles)
Speed (Miles Per Hour)
1
1.5
2
2.5
t
First, let's get the unit rate.
1.5 hours for 915 miles, so
[tex]\frac{1.5 hours}{915 miles} = \frac{1 hour}{x.miles}[/tex]
Cross multiplying gives us 1.5x = 915, divide by 1.5, and we get 610 miles. This is the answer for the top left. This means the plane was going 610 mph.
The speed will be constant because it tells us this.
Then, we multiply 610 by the time to fill in the rest of the distances.
For t, we can figure out the distance is 610 times t, as you can see I have written down.
