Answer:
(a) 4x=5(x-18)
(b) ∠A=∠B=360°
Step-by-step explanation:
Corresponding angles : when two lines are crossed by a transversal , the angle in matching corners are called corresponding angles.
Since the corresponding are congruent.
Therefore,
∠A=∠B
⇔4x=5(x-18)
⇔4x=5x-90
⇔4x-5x=-90
⇔-x=-90
⇔x=90
Therefore ∠A=∠B= 4×90°=360°

The group wants to leave a 15% tip and the bill 24.20 how much do they leave
Answer:
27.83
Step-by-step explanation:.15(24.20)=3.63
3.63+24.20+27.83
To calculate a 15% tip on a $24.20 bill, convert 15% to a decimal (0.15), and multiply this by the total bill. The tip should be $3.63.
Explanation:The concept behind leaving a tip is to provide payment that is a certain percentage of the total bill. In your query, you want to leave a 15% tip on a bill of $24.20. To figure out how much the tip would be, you would multiply the total bill by the tip percentage.
First, you need to convert the tip percentage into a decimal form. To do that, you divide the percentage by 100. So 15 divided by 100 is 0.15.
Next, you multiply the total bill by this decimal. In this case, 24.2 (the total bill) multiplied by 0.15 equals 3.63. Thus, the tip they should leave is $3.63.

The sum of two numbers is 21,and their difference is 9
Answer:
The numbers are 15 and 6.
Step-by-step explanation:
We can solve the problem algebraically (using equations). First, write equations that represent the situation.
Choose variables to represent the numbers:
let the numbers be "x" and "y"
Take apart each section of the problem and make an equation.
"The sum of two numbers is 21"
x + y = 21 Sum means the answer when you add numbers
"Their difference is 9"
x - y = 9 Difference means the answer when you subtract numbers
Using the two equations, you can solve using elimination. With this method, you get rid of one of the variables, so you can easily solve for the other one. You can use elimination when one of your variables have the same variable number. Both equations have "1x" and "1y" ("1" is never written).
Add the equations together by adding normally, with each of the terms with the same variable.
. x + y = 21 Add each term
+ x - y = 9 (x + x = 2x) (y + (-y) = 0) (21 + 9 = 30)
. 2x + 0 = 30 "y" variable cancelled out
. 2x = 30
. 2x/2 = 30/2 Divide both sides by "2" to isolate "x"
. x = 15 Answer for one number
To find the other number, substitute 'x' for 15 into one of the equations.
x + y = 21
15 + y = 21 Isolate "y" now
15 - 15 + y = 21 - 15 Subtract 15 from both sides
y = 21 - 15 15-15 cancelled out on the left side. Solve right side.
y = 6 Answer for second number
Therefore the two numbers are 15 and 6.

A bicycle wheel travels 26π in. for each revolution. What is the radius of the wheel?
Answer:
13
Step-by-step explanation:
Circumference=2πr
2πr=26π
2r=26
r=13
Final answer:
The radius of a bicycle wheel that travels 26π inches per revolution is found using the circumference formula. By solving 26π = 2πr, the radius is determined to be 13 inches.
Explanation:
The question asks to determine the radius of a bicycle wheel that travels 26π inches per revolution. To find the radius, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius. Since we know the wheel travels 26π inches for each revolution, this distance is the circumference of the wheel.
Setting up the equation 26π = 2πr, we can solve for the radius r by dividing both sides of the equation by 2π:
26π = 2πrr = (26π) / (2π)r = 26 / 2r = 13 inchesThe radius of the bicycle wheel is 13 inches.
Janice is creating a scrapbook page with vertices (2,1), (7,1), (7,7), and (2,7). What is the area of the page she will be covering if each grid represents 4 square inches?
Answer:
The actual area of the page will be 120 square inches.
Step-by-step explanation:
Janice is creating a page of scrapbook having vertices (2,1), (7,1), (7,7), and (2,7).
If we plot the points on the coordinate plane then we will see that the page is of a rectangular shape with length (7 - 1) = 6 units which is parallel to the y-axis and width (7 - 2) = 5 units which is parallel to the x-axis.
So, the area of the page is (6 × 5) = 30 square units.
Now, given that 1 square unit is equivalent to 4 square inches.
Therefore, the actual area of the page will be (30 × 4) = 120 square inches. (Answer)

Nat had some stamps. He divided them into sets
of six to put in his album. He made 17 sets. How
many stamps did Nat have?
Answer:
102
Step-by-step explanation:
Nat had a total of 102 stamps which he divided into 17 sets. Each set contained six stamps.
To find out how many stamps Nat had, we need to multiply the number of sets by the number of stamps per set. Nat divided his stamps into sets of six. He made 17 sets. To calculate the total number of stamps, we perform the multiplication:
Multiply the number of stamps in each set (6) by the number of sets (17).
6 stamps/set × 17 sets = 102 stamps
Hence, Nat had 102 stamps in total.
Timothy had 24 meters of ribbon. He cuts it into 2 pieces. The shorter piece is 6 meters long. What is the length of the longer piece?
Answer:
length of longer piece = 18 m
Step-by-step explanation:
Timothy had 24 meters of ribbon
shorter piece is 6 meters
longer piece = actual piece - shorter piece
= 24 - 6
= 18 m
Final answer:
The longer piece of ribbon is 18 meters long, which is obtained by subtracting the length of the shorter piece from the total length of the ribbon.
Explanation:
Timothy started with a 24-meter long ribbon and cut it into two pieces, with the shorter piece being 6 meters in length. To find the length of the longer piece, we subtract the length of the shorter piece from the total length of the ribbon.
Length of the longer piece = Total length of the ribbon - Length of the shorter piece
Length of the longer piece = 24 meters - 6 meters = 18 meters.
Therefore, the longer piece of ribbon is 18 meters long.

Sydney started biking to the bookstore traveling 9 mph, after some time the bike got a flat so Sydney walked the rest of the way, traveling 7 mph. If the total trip to the bookstore took 7 hours and it was 57 miles away, how long did Sydney travel at each speed?
Answer:
By bike= 4 hours
By walk= 3 hours
Step-by-step explanation:
Given: Sydney travel by bike at 9 mph
Sydney travel by walk at 7 mph.
Total trip time= 7 hours
Distance to bookstore= 57 miles.
Lets assume the time spent travelling by bike be "x".
∴ Time spent travelling by walk is [tex](7-x)[/tex]
Now, lets find the distance travelled on bike and by walk.
we know, [tex]Distance= speed\times time[/tex]
∴ Distance by bike= [tex]9\times x= 9x[/tex]
Distance by walk= [tex]7\times (7-x)[/tex]
Using distributive property of multiplication.
∴ Distance by walk= [tex]49-7x[/tex]
Next, forming an equation for total distance travelled to find x.
⇒ [tex]9x+ (49-7x)= 57\ miles[/tex]
Opening parenthesis
⇒ [tex]9x+49-7x= 57[/tex]
⇒[tex]2x+49= 57[/tex]
Subtracting both side by 49
⇒[tex]2x= 8[/tex]
dividing both side by 2
⇒[tex]x= \frac{8}{2}[/tex]
∴[tex]x= 4\ hours[/tex]
Hence, time spent travelling on bike is 4 hours.
Subtituting the value x to find the time spent travelling by walk.
Times spent travelling by walk= [tex]7-4= 3\ hours[/tex]
hence, time spent travelling by walk= 3 hours

parallel to x = 3 and passes through (6, 1)
Answer:
x = 6
Step-by-step explanation:
x = 3 is the equation of a vertical line parallel to the y- axis.
The equation of a parallel line will therefore be a vertical line.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (6, 1) with x- coordinate 6, thus
x = 6 ← equation of parallel line
Final answer:
The equation of the line that is parallel to x = 3 and passes through (6, 1) is x = 6.
Explanation:
The question relates to finding the equation of a line that is parallel to another line, specifically the line x = 3, and that also passes through a given point, namely (6, 1). Since the line x = 3 is a vertical line, any line parallel to it will also be vertical and have an equation of the form x = k, where 'k' is a constant.
In this case, the line we are looking for must go through the point (6, 1), which means it will have the same x-coordinate as this point. Therefore, the equation of the line is simply x = 6.

In the figure below, F is between E and G, and G is between F and H. IF EG-10, FG-2, and FH-8, find EH
Using the Segment Addition Postulate, we determined that the length of segment EH is 20 units, given the lengths of segments EG, FG, and FH in the figure.
In the given figure, we have three points E, F, G, and H, with F being between E and G, and G being between F and H. We are given the lengths of line segments EG, FG, and FH, and we need to find the length of segment EH.
To find EH, we can use the Segment Addition Postulate, which states that for three collinear points, if one point is between the other two, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.
In this case, we have:
EG + GF = EF
Given that EG is 10 and GF is 2:
10 + 2 = EF
12 = EF
Now, we know the length of segment EF is 12. Next, we can apply the same principle to segments EF and FH:
EF + FH = EH
Substituting the values:
12 + 8 = EH
20 = EH
So, the length of segment EH is 20 units.

Three friends ordered 2 pizzas.Each pizza was cut into 8 slices. If each person ate the same amount of slices, how many slices did each person eat?
Final answer:
When 2 pizzas, each cut into 8 slices, are equally shared among 3 friends, each person would eat 5 and 1/3 slices of pizza.
Explanation:
The question involves dividing a certain number of pizza slices equally among friends. Initially, we have 2 pizzas and each pizza is cut into 8 slices, making a total of 16 slices. To find out how many slices each person ate when the amount is the same for everyone, we simply divide the total number of slices by the number of friends.
Total number of slices: 2 pizzas x 8 slices per pizza = 16 slicesNumber of friends: 3Slices per person: 16 slices \/ 3 friends = 5 and 1/3 slices per personSince a pizza slice cannot be split into a third naturally, practically, each friend would eat 5 slices and a little bit more from another slice.
