Part A
The expressions in the table represent how far two friends rode their bicycles on a bike trail.
Rider Miles Biked
Javier 5n + 1
Aisha 3n + 4
Write an expression that shows the difference between the miles ridden by Javier and the miles ridden by Aisha.
_______________________________________________.
------------------------------------------------
Part B
Fill in the blank question.
If n = 2, how many more miles did Javier ride than Aisha?
___________________________________________.
Q: 11
Answers
5n+1 - (3n+4) ->2n-3
Part B:
two ways to approach this
1:
Javier -> 5(2)+1 =11
Aisha -> 3(2)+4 =10
difference -> 11-10=1
2:
2(2)-3=1
The required expression is 2n - 3 that shows the difference of miles ridden by Javier and miles ridden by Aisha.
And Javier rides 1 more mile from Aisha.
What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations,
Given that,
The expression that represents the miles ridden by Javier = 5n + 1
And miles ridden by Aisha = 3n + 4.
(A)
To find the expression that shows difference of miles ridden by Javier and Alisha,
Subtract both the expression,
= 5n + 1 - (3n + 4)
= 5n + 1 - 3n - 4
= 2n - 3
The expression 2n - 3 shows the difference of miles ridden by Javier and miles ridden by Aisha.
(B)
To find the difference of miles, when n = 2
Substitute n = 2 in expression 2n - 3.
= 2(2) - 3
= 4 - 3
= 1 mile.
Javier travelled one more mile from Aisha.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Length of the garden: [] m.
(b)
The area of a rectangular window is 6734 cm².
If the length of the window id 91 cm, what is its width?
Width of the window [] cm.
Answers
(A):88
(B):74
Explanation:
For (A), first multiply 77 by 2 then subtract from 330
77x2=154
330-154=176
For (A), second divide 176 by 2
176/2=88
Length=88
For (B), divide 6734 by 91
6734/91=74
Hope this helps!
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.

Allison rolls a standard number cube 30 times and records her results. The number of times she rolled a 4 is 6. What is the experimental probability of rolling a 4? What is the experimental probability of not rolling a 4?
Answers
Step-by-step explanation:
Experimental prob is what happened : four was rolled 6 out of 30 rolls
= 6/ 30 = 1/5
the rest of the time ( 24 rolls) it was NOT a 4 = 24/30 = 4/5
6/30 rolls were 4 which multiplied by 100 gives you a percentage of 20 and then the same thing was used to find 24/30 being 80%

Find the area of the circle. Round your answer to the nearest hundredth.
Answers
Answer:
3.14 cm²
Step-by-step explanation:
Given that,
→ Diameter = 2 cm
→ Radius (r) = 2/2 = 1 cm
Formula we use,
→ Area of circle = πr²
Then the area of circle will be,
→ πr²
→ 3.14 × 1 × 1
→ 3.14 cm²
Hence, the solution is 3.14 cm².
Answer:
π
Step-by-step explanation:
Area of a circle = \(r^{2}\)π
1. Find the radius.
You should view the "length" of this circle as the diameter of the circle. So the diameter of the circle is 2 cm ⇒ r = \(\frac{2}{2}\) where the numerator is the diameter of the circle (2) and the denominator is always 2. So the radius is 1. The radius is half the length of the diameter.
2. Substitute the values.
A = \((1)^{2}\)π Always put the radius in parentheses before evaluating.
A = π \(1^{2}\) = 1 and 1 · π = π

Which of the following explains the student's error?
Multiple choice questions.
cross out
A)
The two angles must equal 90°, so 2x+6+60=90
C)
The two angles do not equal 180°. They are vertical angles, so 2x+6=60
D)
The student should have added 66 to both sides of the equation instead of subtracting 66.
Part B
Fill in the blank question.
What is the correct solution?
Answers
The correct explanation for the student's error is: (C) The two angles do not equal 180°. They are vertical angles, so 2x+6=60
Vertical angles are pairs of angles formed when two lines intersect. These angles are opposite each other and have equal measures. However, the student incorrectly assumed that the vertical angles were supplementary angles (adding up to 180°).
As a result, they set up the equation as 2x + 6 + 60 = 180, which does not apply to vertical angles. This is why option C explains the error by stating that the two angles are vertical angles, and the correct equation should be 2x + 6 = 60.
To solve the correct equation for 'x', which is 2x + 6 = 60, follow these steps:
Start with the equation: 2x + 6 = 60Subtract six from both sides of the equation: 2x = 54Divide both sides by 2: x = 27The correct solution is x = 27, which means that the value of 'x' that satisfies the equation 2x + 6 = 60 is 27. This correctly reflects the measure of the angle within the given context.
In summary, the student's error stemmed from misunderstanding the nature of vertical angles and incorrectly assuming that they were supplementary angles. By recognizing the correct characteristics of vertical angles and applying the appropriate equation, the solution can be accurately determined as x = 27.
