After 4 new students joined a class, the class had 32 students.
Which equation can be used to find x, the number of students in the class before the students joined?
A. x/4 = 32
B. x - 4 = 32
C. 4x = 32
D. x + 4 = 32
Answers
Explain: if 4 new students joined, that’ll add up to the original number which is x.
So the equation will be x + 4 = 32

Please Help!!! A bicycle has wheels 28 inches in diameter. tachometer determines that the wheels are rotating at 180 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road.
Answers
Answer:
402.336 meters per minutes
Step-by-step explanation:
revolutions per minute = speed in meters per minute / circumference in meters.
Diameter = 28 inches
Circumference of the wheel = 2πr
r = Diameter/2 = 28/2 = 14
Circumference = 2 × π × 14
= 87.964594301 inches
Approximately = 88 inches
Note that:
1 inch = 0.0254 metre
88 inches = x
x = 88 × 0.0254 meters
x = 2.2352 meters
Hence:
Revolutions per minute = Speed in meters per minute / circumference in meters.
Speed = Revolutions per minute × circumference in meters.
Speed = 180 RPM × 2.2352 meters
Speed = 402.336 meters per minutes
Speed of the bicycle traveling down the road = 84π.
It is given that
Diameter of the wheel (2r) = 28 inches, where 'r' is the radius
Speed N(in revolutions per minute) = 180rpm
What is the formula for angular speed?Angular speed ω = [tex]\frac{2\pi N}{60}[/tex]radian per second.
[tex]w= \frac{2*\pi*180 }{60 } = 6\pi[/tex] radian per second
Speed of bicycle V = r*ω
Where,
r= radius of the wheel
[tex]V = 14*6*\pi = 84\pi inches/second[/tex]
Therefore,
speed of the bicycle traveling down the road = 84π.

Add 3 + 2
5 = r - 8
Add 8 to 5 while canceling it out

13 - 8 = 5
That is a true statement so an expression would be
3 + 2 = r - 8
KEVI is an isosceles trapezoid.
If KN 10, NV = x, and IE = 2x+6,
what is the length of KV?
Answers
Answer:
14
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.
An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.
From the question:
KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)
From line segment addition postulate:
KV = KN + NV
substituting:
2x + 6 = 10 + x
2x + 6 - x = 10
x + 6 = 10
x = 10 - 6
x = 4
KV = 2x + 6
substituting x = 4:
KV = 2(4) + 6
KV = 14

His foot touched the protruding bough that was the trigger. Even as he touched it, the general sensed his danger and leaped back with the agility of an ape. But he was not quite quick enough; the dead tree, delicately adjusted to rest on the cut living one, crashed down and struck the general a glancing blow on the shoulder as it fell; but for his alertness, he must have been smashed beneath it. He staggered, but he did not fall; nor did he drop his revolver. He stood there, rubbing his injured shoulder, and Rainsford, with fear again gripping his heart, heard the general's mocking laugh ring through the jungle.

Answers
Answer:
Its nothing complicated, you just have to combine all the like terms, just make sure the lvariables are the same before combining of course.
so assuming the gaps missng are exponents
the solution is the same exact thing
it can’t be simplified anymore since 16q^3 or -48q^2 can’t due to different exponents which thefore can’t combine
same with 32 q, nothing combines
