After the solution of the two-step equation, we can conclude that R = 5.
What do we mean by two-step equations?A two-step equation is one that must be solved in two steps. First, we must eliminate any constants that are on the same side as the variable. To solve, isolate the variable by itself using inverse operations. Remember that whatever you do to one side must be done to the other.So,
Given: R/4 - 9.8 = 10.2Then,
R/4 - 9.8 = 10.2R/4 - 9.8 + 9.8 = 10.2 + 9.8R/4 = 20R = 20/4R = 5Therefore, the value of R is 5.

What is referred as the unitary method?It is a technique that determines the value of a single unit through subtracting the significance of multiple units from the value of a single unit.
The unitary method provides the value of many items, and we must either figure out the amount of more or lesser items.To do so, we must first figure out the worth of one item by division and afterwards multiply the value of more and fewer items.Now, the given question;
The scale of a map is 3 ft = 84 miles
Using unitary method for solving this.
Convert the value for 1 foot.
1 foot = 84/3 miles = 28 miles.
Now, calculate the value for the map of 4.5 ft.
4.5 feet = 28×4.5 miles
4.5 feet = 126 miles
Therefore, the value for map of 4.5 feet is estimated as 126 miles.

Denver, Colorado often experiences snowstorms resulting in multiple inches of accumulatedsnow. During the last snow storm, the snow accumulated at (0.8) inch/hour. If the snow54continues at this rate for hours, how much snow will accumulate?
Answer:
43 inches
Step-by-step explanation:
Accumulation rate per hour = 0.8 inch / hour
If the snow continues at that rate for 54 hours ;
To obtain the amount of snow that will accumulate, we multiply the Accumulation rate per hour by the number of hours given ;
Accumulation rate per hour * number of hours
= 0.8 inch/hour * 54 hours
= 43.2 inches
= 43 inches (nearest whole number)

I WILL GIVE BRAINIEST!! What is 5x+2y=24 in slope intercept form?
Answer:
I'm not sure what you mean but I will solve for everything
2y = 24 - 5x
y = -(5/2)x + 12
y int. = 12
slope is -5/2
x int = 24/5
I get it now
slope int. form is y = mx + b where m is -5/2 and b is 12
Lian's work is shown below. Steps Lian's Work Step 1 s + 40 = 68 Step 2 s + 40 minus 40 = 68 minus 40 Step 3 s = 28 In which step, if any, did Lian first make a mistake in her work? step 1 step 2 step 3 no mistake
Answer:
No mistakeStep-by-step explanation:
Given the equation solved by Lian expressed as;
s + 40 = 68
Lian is to find the value of s from the equation, to do that you will follow the steps below;
Step 1: Substract 40 from both sides of the equation;
s + 40 - 40 = 68 - 40
Step 2: Solve for s;
s + 40 - 40 = 68 - 40
s + 0 = 68 - 40
s = 28
Based on the calculation, we can say that Lian made no mistake when solving
Answer:
D, no mistake.

original amount = spent + remaining
original amount = 4.76 + 16.88
= $21.64
Answer:
Michelle started with $21.64.
Step-by-step explanation:
To solve this problem, we simply need to add he current price, or $16.88, to the amount she spent, or $4.76.
16.88 + 4.76 = $21.64
Therefore, Michelle started with $21.64.

Use the equation to identify the slope and y-intercept, and graph on the coordinate plane. y = -2/3 x + 6. m = b =
Answer:
(Slope) M = -2/3
(Y Intercept) B = 6
When you put the number down for the slope, do not include the x.
(The picture shown is the answer for what the equation is graphed in this case, if your graph is not big enough, read "Step-by-step explanation:".)
Step-by-step explanation:
When dealing with slopes, we use this formula: y = mx + b.
m - # before variable, this is your rise/run.
b - y intercept, this is the point you start on the graph.
When graphing, you need to put b (y intercept, "beginning") on the graph, in this case it's 6, so you need to put it at (0,6). Next, you use the rise/run. To do this, the numerator (-2) will be your "rise", so you move down 2, since this is a negative number. Then, your denominator (-3) will be your "run", so you move left 3, since this is a negative number.
If the graph is not big enough to go down or up, or left or right however much for the rise/run, turn the number (for ex. 2/3) positive if negative, and negative if positive, and use the rise/run to graph it.
Hope this helped, have a nice day.

This is how I would graph it. Hope this helps! :)

At the start of the challenge, Marisol is able to complete 32 sit-ups and plans to increase the number of sit-ups she completes daily by 2. At the start of the challenge, Kelly is able to complete 28 sit-ups and plans to increase the number of sit-ups she completes daily by 3. Which system of equations can be used to determine the number of days it will take for both to complete the same number of daily sit-ups?
Answer:
The system of equations can be used to determine the number of days it will take for both to complete the same number of daily sit-ups?
32 + 2d = 28 + 3d
The number of days it will take for both to complete the same number of daily sit-ups is 4 days
Step-by-step explanation:
Let the number of days it would take them to do daily sit ups be represented by d
At the start of the challenge, Marisol is able to complete 32 sit-ups and plans to increase the number of sit-ups she completes daily by 2.
= 32 + 2d
At the start of the challenge, Kelly is able to complete 28 sit-ups and plans to increase the number of sit-ups she completes daily by 3.
= 28 + 3d
We equate both Equations together
Marisol = Kelly
32 + 2d = 28 + 3d
The system of equations can be used to determine the number of days it will take for both to complete the same number of daily sit-ups is given as:
32 + 2d = 28 + 3d
Solving further:
We collect like terms
32 - 28 = 3d - 2d
d = 4 days
Hence, it will take for both of then 4 days to complete the same number of daily sit-ups .

Triangle ABC has the following vertices:
• A(7,-2)
• B(-1,-8)
• C(5,0)
Is triangle ABC an isosceles triangle, and why?
Choose 1 answer:
A. Yes, because AB = BC.
B. Yes, because AC = BC.
C. No, because AC is longer than AB.
D. No, because ABC doesn't have a pair of sides with equal lengths.

An isosceles triangle is a triangle whose two sides are of equal length. Triangle ABC is an isosceles triangle because of AB= BC.
What is an Isosceles triangle?An isosceles triangle is a triangle whose two sides are of equal length while the third side is of different length.
For the triangle to be an isosceles triangle, we need to find the length of each side of the triangle. Therefore, the length will be,
[tex]AB = \sqrt{(-1-7)^2+(-8-(-2))^2} = \sqrt{(-8)^2+(-6)^2} = 10[/tex]
[tex]BC = \sqrt{(5-(-1))^2+(0-(-8))^2} = \sqrt{(6)^2+(8)^2} = 10[/tex]
[tex]AC = \sqrt{(5-7)^2+(0-(-2))^2} = \sqrt{(-2)^2+(2)^2} = 2\sqrt2[/tex]
Since for a triangle to be an isosceles triangle, it is needed that the two sides of the triangle must be equal while the third side should have different lengths, and as in the given triangle the length of AB=BC. It is an isosceles triangle.
Hence, triangle ABC is an isosceles triangle because of AB= BC.
