Answer:
Step-by-step explanation:
Item 1:
Discount = Original price - discount price
= 22.50 - 13.50
= $ 9
Discount percentage = [tex]\frac{9}{22.50}*100\\\\[/tex]
= 40%
Discount percentage = 40%
Tax = 14.31 - 13.50 = $0.81
Tax% = [tex]\frac{0.81}{13.50}*100\\\\[/tex] = 6%
Tax percentage = 6%
Item 2:
Tax = 6% of 16.20
= 0.06 * 16.20
= 0.972
Tax = $ 0.97
Total price (including tax )= 16.20 + 0.97 = $ 17.17
x = $ 17.17
Item 3:
Discount = 40% of 32.50
= 0.4 * 32.50
= $ 13
y = 32.50 -13
y = $ 19. 50
Tax = 6% of 19.50
= 0.06 * 19.50
= 1.17
z = 1.17 + 19.50
Z =$ 20.67

lee spent $26.85 for 3 yards of material what was the cost of 9 yards?
Answer:
$80.55
Step-by-step explanation:
Answer: $80.55
Step-by-step explanation:
First way:
3 yards cost $26.85
1 yard will cost $26.85 ÷ 3
26.85 ÷ 3 = 8.95
1 yard costs $8.95
9 yard will cost $8.95 × 9
8.95 × 9 = 80.55
9 yards cost $80.55
Second way:
3 yards cost $26.85
9 yards will cost $26.85 × 3
26.85 × 3 = 80.55
9 yards cost $80.55
Hope this helped!

The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair $7, 100 is collected. How many adults and how many children were in the fair.
Answer:
580 children
420 adult
Step-by-step explanation:
y=1000 -x
-5x+10000=7100
-5x=-2900
x=580
1000-580=420 y=420

Given: AD || BC and AD ≅ BC
Prove: AB || CD
Answer:
Statement 1: it is a parallelogram
Reason 1: if one pair of sides of a quadrilateral are parallel and congruent sides, then it is a parallelogram.
Statement 2: AB is parallel to CD
Reason 2: in a parallelogram opposite sides are parallel.

As an estimation we are told 5 miles is 8 km.
Convert 70 miles to km.
km
Answer: 112 km
=====================================================
Work Shown:
(5 miles)/(8 km) = (70 miles)/(x km)
5/8 = 70/x
5*x = 8*70 ... cross multiply
5x = 560
x = 560/5 .... divide both sides by 5
x = 112
According to the given estimation, 70 miles converts to 112 km.
The more accurate conversion is approximately 70 miles = 112.65408 km, so this estimation isn't too far off.
2) Pranavi can hike 4 mile in 7% minutes. How long would it take her to hike

Find the value of x and y
Answer:
x = 8
y = 29
Step-by-step explanation:
By verticle angles theorem, the angles with the measure of ( 4x + 17 ), and the angles with the measure of ( y + 20 ) are equal.
Verticles angles theorem states, when two lines intersect, there are four angles formed. The angles opposite to each other will have the same measure or congruent measures.
Hence one can say that;
4x + 17 = y + 20
Inverse operations;
4x + 17 = y + 20
-17 -17
4x = y + 3
-3 -3
4x - 3 = y
Assuming that lines "m" and "n" are parallel, then the angles with the measure of ( 5x + 9 ) and the angles with the measure of ( y + 20 ) are congruent.
When two lines are parallel and are intersected by another line (transversal line), then the angles that are alternate and interior are congruent, in other words, the same measure.
Based on that, one can say;
5x + 9 = y + 20
Earlier it was found that;
y = 4x - 3
Now substitute that into the previous equation, and solve using simplification and inverse operations;
5x + 9 = 4x - 3 + 20
5x + 9 = 4x + 17
-9 -9
5x = 4x + 8
-4x -4x
x = 8
Back solve to find y
y = 4x - 3
y = 4(8) - 3
y = 32 - 3
y = 29
can anyone answer this question
Given 2X + 4Y = 13 and 3X + Y = 2, what is the value of X?
Answer:
x = -1/2
Step-by-step explanation:
2x + 4y = 13
3x + y = 2 (you can multiply this equation by -4 in order to eliminate the y-term)
-4(3x + y = 2) = -12x - 4y = -8
+ 2x + 4y = 13
-10x = 5
x = -5/10 or -1/2
x(-1/2) + 4y = 13
-1 + 4y = 13
4y = 14
y = 14/4 or 7/2 or 3 1/2

Given:
In an isosceles triangle,
One base angle = (4x-15)°
Vertex angle = 95°
To find:
The value of x.
Solution:
Let the triangle be ABC.
We have,
[tex]m\angle A=95^\circ[/tex]
[tex]m\angle C=(4x-15)^\circ[/tex]
Since ABC is an isosceles triangle and AB=AC, therefore, the base angles are equal.
[tex]m\angle B=m\angle C=(4x-15)^\circ[/tex]
Using angle sum property of triangles, we get
[tex]m\angle A+m\angle B+\angle C=180^\circ[/tex]
[tex]95^\circ+(4x-15)^\circ+(4x-15)^\circ=180^\circ[/tex]
[tex](8x+65)^\circ=180^\circ[/tex]
[tex](8x+65)=180[/tex]
On further simplification, we get
[tex]8x=180-65[/tex]
[tex]8x=115[/tex]
[tex]x=\dfrac{115}{8}[/tex]
[tex]x=14.375[/tex]
Therefore, the value of x is 14.375.
What is the equation of the line that passes through the point (5,−2) and has a slope of -2/5
Answer:
y= -(2/5)x
Step-by-step explanation:
When you graph this line you can see it clearly passes through the point (5,-2)
Answer:
y + 2 = -2/5 (x - 5)
OR
y = (-2/5)x
Step-by-step explanation:
There are many ways you can find the equation.
There are two main ones, one called point-slope form, and the other called slope intercept form.
Point-slope form is easy. All you need a a point on the line, and the slope! Since they give you that in the question, all you need to do is plug things in.
Point slope form is y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])
x and y are any points. [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that the problem gives you. m is the slope.
The equation would be y + 2 = -2/5 (x - 5).
Slope intercept form is a bit harder. You need a point and the y-intercept.
Since you already have the slope, all you need to find is the y-intercept.
Slope intercept form is y = mx + b
x and y are the given points. m is the slope, and b is the y-intercept.
The y intercept is when the x value of a point is 0.
To find b, you can plug in the information you have, which is the point and the slope.
y = mx + b
-2 = (-2/5)(5) +b
-2 = -2 +b
b = 0
Since b is 0, the equation would just be y = (-2/5)x.
