the length of a board is 2 5/8 feet long. If 5/6 of a foot is trimmed off, find the new length
Answers
Answer:
New length is 3 3/20 ft.
Step-by-step explanation:
The total board is 2 5/8 feet long. And since 5/6 of a foot is trimmed off, that means each piece of wood is 5/6 feet.
We can now set up an equation like this ---> 5/6 ⋅ x = 2 5/8
Now we're going to simplify ---> 5/6 ⋅ x = 2 5/8
5/6 ⋅ x = 21/8
(multiply both sides by 6)
5x = 63/4
(divide both sides by 5)
x = 63/20
x= 3.15
So, the new length is 3.15 feet long, or 3 3/20 in mixed fraction.

Bottom half starting from “Given: XY = x + 6”
Answers
Problem 22
Answer: x = 7-----------------------
Explanation:
Segments XY and YZ add up to segment XZ
XY + YZ = XZ
(x+6) + (3x+1) = 5x
4x+7 = 5x
7 = 5x-4x
7 = x
x = 7
===============================================================
Problem 23
Answer: XY = 13-----------------------
Explanation:
We'll use the result in the previous problem to find that,
XY = x+6
XY = 7+6
XY = 13
===============================================================
Problem 24
Answer: YZ = 22-----------------------
Explanation:
Similar to problem 23, we'll use the value of x = 7 to find that,
YZ = 3x+1
YZ = 3*7+1
YZ = 21+1
YZ = 22
===============================================================
Problem 25
Answer: XZ = 35-----------------------
Explanation:
We have two options. We could add the results of the last two problems
XZ = XY + YZ = 13+22 = 35
Or we could compute XZ directly like so
XZ = 5x = 5*7 = 35
Either way, we get the same result. The fact we get the same value both times helps confirm we have the correct x value and the correct lengths of XY and YZ.
Answer:
x = 7XY = 13YZ = 22XZ = 35Concept:
Here, we need to know the idea of the segment addition postulate.
The segment addition postulate states the given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC. In another word, if 3 points A, B, and C are collinear and B is between A and C, then AB + BC = AC.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
XY = x + 6
YZ = 3x + 1
XZ = 5x
Given expression deducted according to the segment addition postulate
XY +YZ = XZ
Substitute values into the expression
x + 6 + 3x + 1 = 5x
Combine like terms
4x + 7 = 5x
Subtract 4x on both sides
4x + 7 - 4x = 5x - 4x
x = 7
Find the value of XY
XY = x + 6 = (7) + 6 = 13
Find the value of YZ
YZ = 3x + 1 = 3 (7) + 1 = 22
Find the value of XZ
XZ = 5x = 5 (7) = 35
Check:
Left-hand side: XY + YZ = 13 + 22 = 35
Right-hand side: XZ = 35
35 = 35

Anthony travels 48 miles by car in the same time it takes him to travel 12 miles on his
bike. His average rate of speed by car is 24 miles per hour faster than his average rate of speed by bike. What is the average rate of speed for both the car and the bike?
Answers
Answer:
Anthony's average speed by car is 32 miles per hour and his average speed by bike is 8 miles per hour.
Step-by-step explanation:
Let the average rate (in miles per hour) at which Anthony travels by car be c and by bike be b.
His average rate of speed by car is 24 miles per hour faster than his average rate of speed on bike. In other words:
[tex]c = b + 24[/tex]
Anthony travels 48 miles by car in the same amount of time it takes him to travel 12 miles by bike.
Recall that distance is given by the rate multiplied by the time t.
Hence, c multiplied by time t equals 48 miles:
[tex]\displaystyle ct = 48[/tex]
Likewise, b multiplied by the same time t equals 12 miles:
[tex]bt = 12[/tex]
Solve. We can multiply the second equation by four:
[tex]4bt = 48[/tex]
Substitute:
[tex]ct = 4bt[/tex]
Divide:
[tex]c = 4b[/tex]
Since c = b + 24:
[tex](b + 24) = 4b[/tex]
Solve for b. Subtract:
[tex]24 = 3b[/tex]
And divide:
[tex]b = 8\text{ miles per hour}[/tex]
Hence, Anthony bikes at an average rate of 8 miles per hour.
Since his average speed by car is 24 miles per hour faster, his average speed by car is 32 miles per hour.
In conclusion, Anthony's average speed by car is 32 miles per hour and his average speed by bike is 8 miles per hour.

The correct choice is option B. (5, 2)
Step-by-step explanation:
The rotation rule of 180° is = (x ,y) -> ( -x , -y) .
Coordinates of C before the rotation are ( -5 , -2) so according to the rule above they will now be = C'( 5 , 2 ) .
Therefore, the ordered pair for C' is (5, 2) after the 180 degrees rotation.

Answers
Answer:
140
Step-by-step explanation:
For every 2 hours, the number goes up 140 miles.
Note: it does not ask for the MPH, it asks for Rate of Change.
Rate of Change is asking for the difference between numbers from one circumstance to the next. For example, in this question, as the table goes up 2 hours in each section, so does miles traveled. Calculate the difference in miles driven for each section to concur that the Rate of Change is 140.
Answer:
70 mph
Step-by-step explanation:
The rate of change is measured as the ratio of the difference between any 2 ordered pairs from the table
Using (4, 280 ) and (6, 420 ) , then
rate of change = [tex]\frac{420-280}{6-4}[/tex] = [tex]\frac{140}{2}[/tex] = 70 mph
