A math teacher asks Nico and Katya to solve the following word problem.
A car travels 98 miles in 1.7 hours on a freeway where the speed limit is 55 mph.
Was the car speeding?
Nico and Katya both agree that they should use their calculators to divide the miles by the hours to find the speed of the car, and then compare the answer to 55 mph. However, Nico says it's okay to round what his calculator says to the nearest whole number. Katya says that because the calculator displays eight numbers after the decimal point, they shouldn't round. She says they should write down exactly what the calculator shows.
Do you agree with Nico or with Katya?
In a short paragraph, explain who you agree with and provide the reasons why.
Answers
Answer:
Yes, the car was speeding. I agree with Nico.
Step-by-step explanation:
When you divide 98 miles by 1.7 hours, the answer is 57.6470588. I agree with Nico because it is okay to round because no matter what, the number before the decimal number (57) will always be a greater number than 55. It is easier to round the number for the equation, so Nico is correct in this situation.

Solve the following system of equations using substitution.
4x + 2y = 12
x = y + 3
Answers
Answer:
x = 3
y = 0
Step-by-step explanation:
The method of substitution is when one solves an equation for one of the variables, and then substitutes the expression into the other equation. After doing so, one will solve the other equation for the remaining variable and then backsolve for the first variable.
4x + 2y = 12
x = y + 3
The second equation is already sovled for parameter (x), subttiute this into the other equation,
4(y + 3) + 2y = 12
Distribute,
4y + 12 + 2y = 12
Simplify,
6y + 12 = 12
Inverse operations,
6y + 12 = 12
-12
6y = 0
/6
y = 0
Backsolve for (x), substitute the value of (y) into the equation for (x) and solve,
x = y + 3
x = 0 + 3
x = 3
Answer: look at the picture, sorry I can’t solve x = y + 3 for x.

The Area of Δ ABC = 219.13
Step-by-step explanation:
The hard part about this problem is finding the area without the height
The formula to do this is Area = [tex]\sqrt{S(S-A)(S-B)(S-C)}[/tex]
A, B, C represent the sides
S represents [tex]\frac{1}{2}[/tex] (A + B + C)
In this equation, we will make the base be A, and the other two sides will be B and C
Sides B and C are the same length because they meet at a 90° angle
Lets plug the numbers into the variables
A = 28
B= 21
C= 21
Remember: S represents [tex]\frac{1}{2}[/tex] (A + B + C)
S = [tex]\frac{1}{2}[/tex] (28 + 21 + 21)
S = [tex]\frac{1}{2}[/tex] (70)
S = 35
Lets plug the numbers into the Area Formula now!
Area = [tex]\sqrt{35(35 - 28)(35 - 21)(35 - 21)}[/tex]
According to the order of operations, we need to do the calculations in parentheses first
35 - 28 = 7
35 - 21 = 14
35 - 21 = 14
14 x 14 x 7 = 1372
1372 x 35 = 48020
[tex]\sqrt{48020}[/tex] = 219.13
The Area of Δ ABC = 219.13

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.
So, a traingle is 180 degrees.
A line is also 180 degrees.
We know that the angles that make up the triangle are 46, 90, and a missing angle
We need to find the missing angle to find x
To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.
So:
180-90
=
90
90-46
=
44
So we know the missing angle is 44 degrees.
Let subtract the missing angle(44 degrees) by the 180 degrees of the line:
180-44
=
136
THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER
So x equals 136. This is the missing angle x.
So, remember, both the line and the traingle are 180 degrees.
They both need to find the missing value, which we know is 44
The rest of both the triangle and line is 136 degrees.
Well, 136 degrees on the triangle is the known 90+46 degrees.
Since this will be the same on the line, we can think of x as:
90+46
This looks like answer 1.

Answers
Answer:
A) The area of parallelogram 1 is 4 square units greater than the area of parallelogram 2.
The area of parallelogram 1 is 2 square units greater than the area of parallelogram. Option 2 is correct.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
A₁ is the area of parallelogram 1
A₁ is the area of parallelogram 2
l₁ is the distance between the points (2,6),(0,2)
l₂ is the distance between the points (4,0)(0,2)
b₁ is the distance between the points (2,0),(0,-2)
b₂ is the distance between the points (2,6),(4,-6)
A₁ = l₁ × b₁
A₁=4.47 ×4.47
A₁ = 19.89 sq.unit
A₂=l₂×b₂
A₂=2.82 × 6.342
A₂=17.88 sq.unit
A₁-A₂ = 19.89 sq.unit - 17.88 sq.unit'
A₁-A₂= 2.01
The area of parallelogram 1 is 2 square units greater than the area of a parallelogram.
Hence,option 2 is correct.
