Step-by-step explanation:
yazmin noticed her favorite workout tops were on sale for $6.00 off the original price. she purchased 4 of the tops and spent a total of $51.80. write and solve an equation to determine x, the original price of the workout tops?
the original price of the workout tops is $18.95
How to find the original price of the workout tops?
Let's say that the original price is x, we know that the tops are on sale for $6.00 off the original price, so if Yazmin buys 4 of these, the cost will be:
C(x) = (x - $6.00)*4
And we know that the cost is $51.80, replacing that we get:
$51.80 = (x - $6.00)*4
Now we need to solve this linear equation for x.
$51.80/4 = x - $6.00
$51.80/4 + $6.00 = x = $18.95
We conclude that the original price of the workout tops is $18.95

A theater owner wants to provide enough seating for 786 people. The main floor has 24 rows of 20 seats in each row. If the balcony has 17 rows, how many seats must be in each row to satisfy the owner's seating requirements?
Answer:
18
Step-by-step explanation:
24 x 20 = 480 (amount of seats on main floor)
786 - 480 = 306 (amount of seats needed on balcony)
306 ÷ 17 = 18 (amount of seats on each row of balcony)
Step-by-step explanation:
The main floor has 24*20 = 480 seats.
So you need 786- 480 = 306 more seats
There are 17 rows in the balcony and let's say there are x seats in each row. Since you need 323 seats, this means
19x = 323
x = 306/17
x = 18
So there must be 18 seats in each row up in the balcony.

An intersection is the point where two lines or curves meet We can find intersections graphically by plotting curves on the same graph and determining their intersection. We can find an intersection algebraically by following these steps: Solve each equation for one of the variables, calling it y. Set the expressions for y found in the first step equal and solve for the other variable, calling it x. This is the x-value of the intersection. Return the x value of the intersection back to one of the original equations and solve for y.This is the y variable for the intersection.In the graph the intersection both functions is the point when f(x)=g(x)
the point of intersection both graphs is (1,5,2)
that means

If ∠1 and ∠ 2 form a linear pair, they are supplementary angles.
∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In the given image ∠1 and ∠ 2 are linear pairs.
Now,
∠1 = ∠3 (opposite angle)
∠2 = ∠4 (opposite angle)
Now,
∠1 + ∠2 + ∠3 +∠4 = 360°
(∠1 + ∠2) + 180° = 360°
(∠1 + ∠2) = 180°
If the sum of two angles is 180° then they will be supplementary angles.
Hence "∠1 and ∠ 2 are linear pairs and have a sum of 180° so they will be supplementary angles".

ZA and ZB are
supplementary angles. If mA = (x + 4)° and m
LB = (2x - 7)°, then find the measure of ZA.
Supplementary angles have a sum of 180°
Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.
( 7x - 15 ) + ( 2x - 3 ) = 180
Now we can combine like terms and use inverse operations to find the value of x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Then Angle A will have a measure of 7x - 15 or 7• 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle b will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°

The longest side of a triangle is twice the length of the shortest side. The remaining side is 20 cm longer than the shortest side. The perimeter of the triangle is 132 cm. What is the length of each side?
Answer:
The triangle has sides lengths 28, 56, 48
Step-by-step explanation:
Let x = the shortest side
So then the longest side will be 2x, because the question said that "the longest side... is twice the length of the shortest side" Then the third side would be x + 20.
The perimeter was given so add all the sides and set it equal to 132.
x + 2x + x + 20 = 132
Combine like terms.
4x + 20 = 132
Subtract 20
4x = 112
Divide by 4.
x = 28
Then use x = 28 to find the lengths of all the sides.
Shortest Side:
x = 28
Longest Side:
2x
= 2(28)
= 56
Third Side:
x + 20
= 28 + 20
= 48

When Angelo drove home from college with an average speed of 71.7 mph and back to college with an average speed of 64.1 mph, she took 5 hours for full trip then the time taken to travel from home to college is 2.63 hours
Given,
The average speed from college to home = 71.7 mph
The average speed from home to college = 64.1 mph
We know,
Speed = Distance / Time
Consider the total distance as x
Time taken = Distance / Speed
Then the time taken to travel from college to home = [tex]\frac{x}{71.7}[/tex] hours
time taken to travel from home to college = [tex]\frac{x}{64.1}[/tex] hours
Total time taken = 5 hours
