Answer:
x = -5
Step-by-step explanation:
First distribute the 5 on the right side of the equation.
10x - 35 = 15x - 10
Then subtract 10x on each side
-35 = 5x - 10
Then add 10 on each side
-25 = 5x
Divide 5 on each side to get x
-25 / 5 = -5
I hope this helps! :)

An airplane is flying at 32,000 feet when it starts it’s decent. It is
descending at a rate of 2000 feet per minute. Let x represent the minutes
of the flights descent and y represent the plane’s altitude.
a. Fill in the table.
b. Write an equation in slope-intercept form for the plane’s altitude.
c. Graph the equation from part (b).
Answer:
10,000
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000
After five minutes the plane is at 10,000. feet.

A cylindrical mailing tube has a length of 20 inches and diameter of 4 inches.
O
What is the approximate volume of the cylinder, to the nearest tenth of a cubic inch?
(Use 3.14 for pi.)
Answer:
Volume = 251.2 cubic inches
Step-by-step explanation:
You get the volume of a cylinder by multiplying the area of the base with the height.
Since the diameter is 4 inches, the radius of the base is 4/2 = 2 inches
So, volume = base area* height
= 2² * 3.14 * 20
= 251.2
The approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
Volume of cylinder is the can be given as,
[tex]V=\pi r^2h[/tex]
Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.
A cylindrical mailing tube has a length of 20 inches and diameter of 4 inches. The radius is half of the diameter of the cyilnder. Thus the radius of the cylinder is,
[tex]r=\dfrac{4}{2}\\r=2\rm\; in[/tex]
Put the value of radius and height of the cylinder in the above formula as,
[tex]V=3.14 (2)^2(20)\\V=251.2\rm\; in^3[/tex]
Thus, the approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.

The doctor's office where you work needs to store 8 filing cabinets with patient information in one of three secure storage rooms. The filing cabinets need a total of 55 square feet of space. The doctor has asked you to identify which room the filing cabinets will fit
Answer:
Square B 9 × 7.5
Step-by-step explanation:
The computation is shown below:
9 × 7 = 63 > 55
8 × 5 = 40 < 55
5 × 10 = 50 < 55
As it can be seen that in only one condition the total of square feet is less and in the other conditions the total of square feet is more
Therefore the option Square B is correct
And, the rest of the options are incorrect

2×10−5
C.
3×10−5
D.

Answer: A. [tex]2\times10^{-6}[/tex].
Step-by-step explanation:
Given: The diameter of bacterium = 0.0000029 meter

A group of friends wants to go to the amusement park. They have $116 to spend on parking and admission. Parking is $10.25, and tickets cost $35.25 per person, including tax. Which equation could be used to determine pp, the number of people who can go to the amusement park?
Answer:
2 people
Step-by-step explanation:
no. of people = x
total parking costs = 10.25x
total tickets cost = 35.25x
total = 10.25x + 35.25x
suppose 3 people go, then the total cost will be
10.25(3) + 35.25(3) = 136.5 and this is greater than 116
Suppose 2 people go then the cost will be
10.25(2) + 35.25(2) = 91 which is less than 116
so only 2 people can go.

180=x+(3x-8)
Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
x=47

For each shape, write an expression for the missing length. Area =9x -6 , length=3x-2, breath =?
the breadth of the rectangle is 3
A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).
Area =9x -6 ,
length=3x-2,
breath =?
Therefore, the area of a rectangle formula states that:
Area of rectangle = Length x Width
A = L * W, where A is the area, L is the length, W is the width or breadth.
now put the given value in the formula
9x-6 = (3x-2 )*W
3( 3x -2) / (3x-2) = W
W =3
Hence , the breadth of the rectangle is 3

A baseball bat factory produces 24,000 bats per day and uses 50 boxes for packing the bats. If the number of boxes needed for packing is proportional to the number of bats produced, how many boxes would be needed on a day when 36,000 bats are produced?
Answer:
Total boxes= 75
Step-by-step explanation:
Giving the following information:
A baseball bat factory produces 24,000 bats per day and uses 50 boxes for packing the bats.
First, we need to determine the number of bats that fits into a box:
Bats per box= 24,000 / 50
Barts per box= 480
Now, the number of boxes for 36,000 bats:
Total boxes= total bats / bats per box
Total boxes= 36,000/480
Total boxes= 75
Answer:75
Step-by-step explanation:
Bats 24000/50

Find h as indicated in the figure. Round to the nearest foot.
By using trigonometric functions and law of sines, the length h indicated in the figure is approximately 87.997 feet.
What is the value of a length of a triangle within a geometric system?
In this system we find a picture of a geometric system formed by the two triangles, one of which with a right angle. We need to use trigonometric functions, law of sines and law of cosine to determine the missing length. First, use the law of sines:
(129 ft) / sin 33.7° = r / sin 26°
r = 129 ft × sin 26° / sin 33.7°
r ≈ 101.920 ft
Lastly, we find the value of the length h by trigonometric functions:
h = r · sin 59.7°
h = (101.920 ft) · sin 59.7°
h ≈ 87.997 ft
The length h indicated in the figure is approximately 87.997 feet.
