all triangles = 180°
180=32+2x+x+15
combine like terms
180=47+3x
180-47=133
133=3x
133/3=44.334 or 44 1/3
2(44.334)= 88.66 ooor 87 if you round it

Answer:
3x²/(3x - 9y)
This should be the simplest form.
Step-by-step explanation:
Combine the fractions:
(5x² - 2x²)/((6x - 6y) - (3y - 3x))
Combine like terms:
3x²/(6x - 3x - 6y - 3y)
Solve.
3x²/(3x - 9y)
Answer:
9x^2
======
6(x - y)
Step-by-step explanation:
Begin by switching the - to a plus. Switch the x and y in the second denominator.
5x^2 2x^2
===== + ======
6x - 6y 3x - 3y
Pull out the common factors in both denominators. Use the distributive property.
5x^2 2x^2
===== + ======
6(x - y) 3(x - y)
Multiply both the numerator and denominator by 2 on the left had fraction.
5x^2 2*2x^2
===== + ======
6(x - y) 2*3(x - y)
5x^2 4x^2
===== + ======
6(x - y) 6(x - y)
Put both numerators over a common denominator. Notice that the + sign shifts up. It shifts up because both fractions have been changed to a common denominator.
5x^2 + 4x^2
===================
6(x - y)
Combine the two numerators since they are of the same power.
9x^2
======
6(x - y)

Calculate the interest earned on a $4,500
saving account that earns 2.5% simple interest over
3 years
Answer:
I = $337.50
Step-by-step explanation:
I = prt
I = 4500(.025)(3)
I = 337.50
The interest earned is $337.50.
What is Simple Interest?The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.
Simple Interest = Principal x Interest Rate x Time/ 100
Given:
Principal= 4500
Rate= 2.5%
Time= 3 years
Using Simple Interest
SI = ( P x R xT)/100
SI = (4500 x 2.5 x 3) /100
SI = 33750/100
SI = $337.50
Hence, the interest earned is $337.50

How to solve for shaded area
Answer:
(a) 12.96 ft²
(b) 21.5 in²
Step-by-step explanation:
(a) For the first diagram
Area of the shaded region (A) = Area of Tripezium- area of circle
A = [1/2(a+b)h]-[πr²]............... Equation 1
Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.
From the diagram,
Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.
Constant: π = 3.14
Substitute these values into equation 1
A = [12(15+6)/2]-(3.14×6²)
A = 126-113.04
A = 12.96 ft²
(b) For the second diagram,
Area of the shaded region (A') = Area of square- area of circle
A' = (L²)-(πr²)............. Equation 2
Where L = lenght of one side of the square, r = radius of the circle
From the diagram,
Given: L = 2r = (2×5) = 10 in, r = 5 in
Substitute these values into equation 2
A' = (10²)-(3.14×5²)
A' = 100-78.5
A = 21.5 in²
Which expression means the same as 25 less than 5y
Answer: 5<y
Step-by-step explanation:25<5y divide both sides by 5 and you get the answer.

x2 + 5x = 2 are shown.
x2 + 5x = 2
x2 + 5x + (StartFraction 5 Over 2 EndFraction) squared = 2 + (StartFraction 5 Over 2 EndFraction) squared
(x + StartFraction 5 Over 2 EndFraction) squared = StartFraction 33 Over 4 EndFraction
Which are solutions of x2 + 5x = 2?
Given:
The equation is:
[tex]x^2+5x=2[/tex]
To find:
The solution of the given equation by completing the square.
Solution:
We have,
[tex]x^2+5x=2[/tex]
We need to add the square of half of the coefficient of x on both sides.
Adding [tex]\left(\dfrac{5}{2}\right)^2[/tex] on both sides, we get
[tex]x^2+5x+\left(\dfrac{5}{2}\right)^2=2+\left(\dfrac{5}{2}\right)^2[/tex]
[tex]\left(x+\dfrac{5}{2}\right)^2=2+\dfrac{25}{4}[/tex]
[tex]\left(x+\dfrac{5}{2}\right)^2=\dfrac{8+25}{4}[/tex]
[tex]\left(x+\dfrac{5}{2}\right)^2=\dfrac{33}{4}[/tex]
Taking square root on both sides, we get
[tex]x+\dfrac{5}{2}=\pm \sqrt{\dfrac{33}{4}}[/tex]
[tex]x=\pm \dfrac{\sqrt{33}}{2}-\dfrac{5}{2}[/tex]
[tex]x=\dfrac{\pm \sqrt{33}-5}{2}[/tex]
[tex]x=\dfrac{\sqrt{33}-5}{2}[/tex] and [tex]x=\dfrac{-\sqrt{33}-5}{2}[/tex]
Therefore, the solutions of the given equation are [tex]x=\dfrac{\sqrt{33}-5}{2}[/tex] and [tex]x=\dfrac{-\sqrt{33}-5}{2}[/tex].

Tyler's brother works in a shoe store. Tyler's brother earns a commission. The store bought a pair of shoes for $32 and sold them for $78. What percentage was the markup?
Answer:
The markup was 143.75%.
Step-by-step explanation:
In order to find the markup, you have to find the difference between the price the store paid for the pair of shoes and the price they sold them for, then divide that by the price they paid for the shoes and the result has to be multiplied for 100:
((78-32)/32)*100=(46/32)*100=1.4375*100=143.75%
According to this, the answer is that the markup was 143.75%.
Kyndal wants to buy a lamp that
originally cost $82, but went on sale for
20% off. The store is having an
additional sale that is 40% off the sale
price. What is the price of the lamp?
Answer:
$39.36
Step-by-step explanation:
Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82
82x0.8= 65.6
Since there is a additional 40% off multiply by 0.4 to get the discount amount
65.6x0.4= 26.24
Subtract the discount from the price
65.6-26.24= 39.36

Answer:
Rico Spent $6.50 on each car.
Step-by-step explanation:If you divided 52 by 8 you get 6.5 in money it would be $6.50.
My answer is reasonable because my estimate ÷ 10 = $6.50
Answer:
The answers are: 6.5$ , divided by, and 5$
Step-by-step explanation:
In order to figure out the price of each toy car, we must divide 52/8 (the total price of the toy cars divided by the number of the cars) which equals to 6.5, meaning that each toy car costs 6.5$, since they all have the same price. We know that this is a reasonable price because say we were to estimate, meaning we'd take a guess without doing any calculations. Let's say we paid 50$ in total, which is easily divided by 10, if we were to round up both numbers, we'd get 5$ each. That's close to the true answer, making it reasonable to take such a guess.

Tom buys a hat for $13.00 plus 11% sales taxes.
Lyn buys a hat for $21.00 plus 9% sales taxes.
a) How much do Tom and Lyn pay for the hats? Show your work.
b) Who spent more on taxes?
Answer:
a)
Tom
Tax = (11/100) × 13
Tax = $1.43
Tom paid 13 +1.43 = $14.43
Lyn
Tax = (9/100)× 21
Tax = $1.89
Lyn paid 21 + 1.89 = $22.89
b) Lyn paid more for taxes.

A cyclist rides his bike at a speed of 27 miles per hour what is the speed in miles per minute? How many miles will the cyclist travel in 2 minutes ? Do not round answer
Answer:
The cyclist can travel 0.9 miles in 2 minutes.
Step-by-step explanation:
1 hour = 60 minutes
Set up a conversion equation:
27 mi/1 hr × 1hr/60 mins
It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes
After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:
27 mi/60 mins
The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?
Set up an equation:
Variable x = number of miles
27 mi/60 mins = x/2 mins
Cross multiply
27 × 2 = 60 × x
54 = 60x
Divide both sides by 60
0.9 = x
