What is the first step when solving the following inequality x+2/-5<4? Group of answer choices A. Add 5 to both sides and DO
LiRa [457]

Assuming we're dealing with \frac{x+2}{-5} < 4, which is the same as writing (x+2)/(-5) < 4, then the answer is choice C.

We multiply both sides by -5 and this will flip the inequality sign.

-------------------------------------

Multiplying or dividing both sides by a negative number flips the inequality sign.

An example would be saying -2x < 10 leads to x > -5

What we can do is divide both sides by -2 and flip the inequality sign, or we could follow the steps shown below

  • -2x < 10
  • 0 < 10+2x ... adding 2x to both sides
  • -10 < 2x ... subtracting 10 from both sides; this is one way to see why the sign flip happens
  • 2x > -10
  • x > -10/2 ..... dividing both sides by 2
  • x > -5

Determine whether $10.62/61lb = $7.05/4lb form a proportion. Explain.
Jlenok [28]
It would be $1.76 for 1 lb, then you would times that by 61 and if it equals 10.62, it is proportional. I multiplied it and got $109.28/ 62 lbs so it can not form a proportion.

If you travel 4 miles around a circle with a radius of 1 mile, what is the central angle (q)?
mixer [17]

Answer:

229.18 degrees

Step-by-step explanation:

The circumference of a circle with radius r is 2×pi×r.

So if it has a radius of 1 mile, then the circumference is 2×pi×1=2pi miles.

So if we travel 4 miles, then the percentage of this circle we traveled is 4/(2pi)=63.66% approximately.

There are 360 degrees in a circle and we want to how much of that rotation belongs to traveling 4 miles of the circumference of a circle that measures 2pi miles. So 63.66%×360 degrees =229.18 degrees.
