Answer:
20. C, 21. A, 22. B
Step-by-step explanation:
20. Terms are numbers with variables next to them.
21. T can be anything. It can't be irrational because timers have a certain number. So for example, swimmer swims in 10 seconds, 18.5 seconds, 18.67 seconds, and so on.
22. If you solve 3x ≥ -12 and 8x ≤ 16, you get 3x ≥ -12; x = -4, and 8x ≤ 16; x = 2.
Hope it Helps!
Plz give brainliest. It would be appreciated!
Answer:
m = -3
Step-by-step explanation:
5m + 20 = 8 + 2m +3
5m + 20 = 11 +2m
3m + 20 = 11
3m = -9
m = -3
Answer:
The correct option is C.
Step-by-step explanation:
The least common multiple (LCM) of any two numbers is the smallest number that they both divide evenly into.
The given terms are
and
.
The factored form of each term is
![n^3t^2=n\times n\times n\times t\times t](https://tex.z-dn.net/?f=n%5E3t%5E2%3Dn%5Ctimes%20n%5Ctimes%20n%5Ctimes%20t%5Ctimes%20t)
![nt^4=n\times t\times t\times t\times t](https://tex.z-dn.net/?f=nt%5E4%3Dn%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t)
To find the LCM of given numbers, multiply all factors of both terms and common factors of both terms are multiplied once.
![LCM(n^3t^2,nt^4)=n\times n\times n\times t\times t\times t\times t](https://tex.z-dn.net/?f=LCM%28n%5E3t%5E2%2Cnt%5E4%29%3Dn%5Ctimes%20n%5Ctimes%20n%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t%5Ctimes%20t)
![LCM(n^3t^2,nt^4)=n^3t^4](https://tex.z-dn.net/?f=LCM%28n%5E3t%5E2%2Cnt%5E4%29%3Dn%5E3t%5E4)
The LCM of given terms is
. Therefore the correct option is C.
Answer:
X- axis is the line at the bottom of the graph and y-axis is the line on the side
Answer:
18
Step-by-step explanation:
The formula X/6 - 11 = -8
Add 11 to both sides of the equation X/6 = 3
Multiply by 6 both sides to cancel out the division
X = 18
