It costs $45 for 3 xylophones and 3 yo-yo's. If you purchased 5 xylophones and
6 yo-yo's, it would cost $80. Set up a system of equations and solve for the
cost of a single xylophone and a single yo-yo.
Step-by-step explanation:
xylophone : x
yo-yo : y
3x + 3y = 45 —(1)
5x + 6y = 80 —(2)
(1)*2 : 6x + 6y = 90 —(3)
(3)-(2):
6x + 6y = 90
-(5x + 6y) = 80
x =10 — (4)
Sub (4) into (1)
3(10) + 3y = 45
30 + 3y = 45
3y = 45-30
y = 15/3
y = 5

Which source would provide the best answer to this question: what was life like for the typical female pirate who lived between 1600 and 1800
. A history book about pirates that has at least one character about female pirates
. An article about the great-great-great grandchildren of a woman pirate
. A movie that stares an actress playing a female pirate
. a guide for little girls who wants to grow up to be pirates
Answer:
A) A history book about pirates that has at least one character about female pirates
Explanation:
A history book about pirates will probably have educated views on a female pirate's life, as it's purpose is to inform.
The article about a female pirate's three-times-great grandchildren will likely not be specific and unbiased enough to have an educated answer to our question.
A movie about a female pirate will likely be dramatized and not have adequately expert ideas on the pirate's life.
A how-to-be-a-pirate guide will not accurately portray a 1600-1800 pirate woman's life. Because it's aimed at young girls, this is not a reliable source either.
So, our best answer should be A.
Good luck ^^

A kite is flying on a string that is 73 feet long. The angle
the kite makes with the ground is 51 degrees. How high
is the kite flying?
Answer:
56.73 ft
Step-by-step explanation:
Given:
51° (angle)
73ft (hypotenuse)
With the given information use sin to determine the height of the kite.
sin51° = x/73
solve for x (height)
x= 73*sin51°
x= 56.73ft

w = weeks
42 + 7w = 133
take away 42 frim each side
7w = 91
divide each side by 7
w = 13
What type of triangle is this triangle?
acute isosceles
obtuse isosceles
Right isosceles
acute scalene
Answer:
obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

2x + 4y = 16
3x - 2y = 8
Solve using substitution method
100 POINTS PLS ANSWER
Answer:
(4,2) or x=4, y=2
Step-by-step explanation:
As your question asks, we'll solve the system of equations by substitution, where we'll solve for the value of one variable and than substitute that value into the other equation and solve for the two variables
we're given the system:
2x+4y=16
3x-2y=8
Let's take the first equation:
you can isolate either x or y, but I'll do x for this problem
2x+4y=16
subtract 4y from both sides
2x=-4y+16
divide both sides by 2
x=-2y+8
now take the second equation (3x-2y=8) and substitute -2y+8 as x
3(-2y+8)-2y=8
do the distributive property
-6y+24-2y=8
combine like terms
-8y+24=8
subtract 24 from both sides
-8y=-16
divide by -8
y=2
we found the value of y. However, we also need to find the value of x
above, we said that x=-2y+8; since we found the value of y, we can substitute that value into the equation and find x
so:
x=-2(2)+8
x=-4+8
x=4
the answer is x=4, y=2. If you need it as a coordinate point, it's (4,2)
Hope this helps!

Sarah uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:Amount of white paint used by Sarah =1.82 pints
Step-by-step explanation:
Amount of blue paint and white paint to paint her bedroom walls.=9.1 pints
Amount of blue paint used =4/5 x 9.1=7.28 pints
Amount of white paint used=Amount of blue paint and white paint to paint her bedroom walls -Amount of blue paint used
=9.1-7.28=1.82 pints

Write the equation in standard form for the circle with radius 4 centered at the origin
Answer:
common form to write the equation of a circle in is the center-radius form. The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.
Answer:
x² + y² = 16
Step-by-step explanation:
We need to write the standard equation of circle with , centre (0,0) and radius 4 unit . The Standard equation of the circle ⭕ is ,
=> ( x - h)² + (y -k)² = r²
=> ( x -0)² + (y-0)² = 4²
=> x² + y² = 16 .
• Hence the equation of the circle is x² + y² = 16.

Please who steps.on how to solve.
Answer:
51°
Step-by-step explanation:
An inscribed angle is half of the arc it intercepts. This means that arc QR is twice m<QTR or 78°.
Since <QSR is a central angle, it equals the arc it intercepts. This means m<QSR equals arc QR which is 78°.
We can say that QS equals to RS because they are both radii, and radii of the same circle are equal. This means triangle QSR is isosceles.
Let <QRS equal x. Because of base angle theorem, <SQR would also be equal to x. Since the angles in a triangle add up to 180, we can write an equation to model the situation:
m<QRS + m<SQR + m<QSR = 180
We can substitute the values we have:
x + x + 78 = 180
2x = 102
x = 51
Since <QRS is equal to x, it is 51°

If 3/7 is written as a decimal, will the digits after the decimal eventually repeat?
A.Yes, because
is an irrational number.
B. Yes, because
is a rational number.
C. No, because
is an irrational number
D. No, because
is a rational number
Answer:
Yes, because its an rational number
Step-by-step explanation:
Solution: by division.
3/7 = 0.42857142857142857142…..
As you can see, the first six decimal places make a loop and become repetitive.
Then I proceeded to divide 100/6. That equals 16 remaning 4. Then counted four digits from0.428571. The 100th digit equals 5.

Answer:
3, 20, 2, and 2.5
Step-by-step explanation:
For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.
On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12
3/12 is 1/4 so the first k is 3.
Second one y = k/x. x is 4 and is 5. So 5 = k/4
20/4 is 5, so the second k is 20.
