Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A
C = 125 + 50t
Studio B
C = 200 + 30t
125 + 50t = 200 + 30t
20t = 75
t = 3.75

You decide to take a trip to Japan to see Mt. Fuji in person. But while you are there, you can bring back some of those rectangular watermelons you’ve heard so much about. Now, you’re packing for your trip. You have two small bags. In order for you to carry a bag on the plane, it must fit inside the Carry-on Baggage Check Box. The Carry-on Baggage Check Box has dimensions of approximately 22" x 14" x 9". Your leather bag has a height of 18 inches, a depth of 12 inches, and a width of 8 inches. Your canvas bag has a height of 18 inches, a depth of 15 inches, and a width of 10 inches.
1. What is the volume of the Carry-On Baggage Check Box?
2. What is the volume of the leather bag?
3. What is the volume of the canvas bag?
4. Which bag will definitely fit into the Check Box? Explain.
Answer:
You have my profile picture
Step-by-step explanation:
Answers:
1. The volume of the carry-on baggage check box is 2772 inches³
2. The volume of the leather bag is 1728 inches³.
3. The volume of the canvas bag is 2700 inches³.
4. The leather bag will definitely fit into the check box.
Hope this helps!
When answering, make sure to put the units, which is inches cubed, which you always use for finding the volume of a figure.

Answer:
A number that can be made by dividing two integers (an integer is a number with no fractional part). The word comes from "ratio". But π (pi) is not a rational number, it is an "Irrational Number".
Step-by-step explanation:
mark me please
Answer:
Since rational numbers are all numbers that can be written as a fraction, and includes positive numbers, negative numbers and the 0. We can conclude that since -3.4 can be written as a fraction it is a rational number.

if y=27 when x= 8 find y when x =11
Answer:
37 1/8
Step-by-step explanation:
The problem probably assumes direct variation
y=kx
IF so, then plug in the values and solve for k
27=k(8)
k = 27/8
y= (27/8)x. Now let x = 11
y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8
y = 37 1/8
the problem is making some assumption about the relation between x and y. The simplest assumption that's likely is direct variation, that x and y are linearly related. The graph is a straight line through the origin with slope = 27/8

Solve for the area of the figure below and show work.
Answer and Step-by-step explanation:
1. We can see that this kite-shape has 4 triangles in it.
The area of a triangle is as follows:
[tex]A = \frac{bh}{2}[/tex]
Where:
b = Base (length)
h = Height
Top Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Bottom Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Top Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Bottom Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Now, we add all the areas together to get the area of the kite figure.
A = [tex]\frac{27}{2}[/tex] +
A = 27 + 12
A = 39
The area of the kite figure is 39 [tex]m^{2}[/tex].
2. We have to find the area of the trapezoid.
(I'm not sure if the 9 is for the entire bottom side length)
If the bottom side length is 9, then we would use the formula:A = [tex]\frac{a + b}{2} h[/tex]
to find the area of the entire trapezoid.
A = [tex]\frac{2.4 + 9}{9}[/tex] × 8.2
A ≈ 46.74 [tex]mi^{2}[/tex]

Find JK................
Answer:
24 unit
Step-by-step explanation:
From the question,
JK = 2×NK.................... Equation 1
Using pythagoras theorem,
a² = b²+ c²................. Equation 2
From the diagram,
a = 15 unit, b = 9 unit, and c = NK
Substitute these values into equation 2
15² = 9²+(NK)²
Solve for NK
225 = 81+(NK)²
(NK)² = 225-81
(NK)² = 144
NK = [tex]\sqrt{144}[/tex]
NK = 12 unit.
Substitute these value of NK into equation 1
JK = 2×12
JK = 24 Unit.

m<3 = 97
m<10 = 97
m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.
