6 1/2
First you find a common denominator. 1/4 = 3/12 and 1/3 = 4/12.
3/12 + 4/12 + 11/12 = 18/12.
18/12 = 6 6/12 = 6 1/2
Answer:
1. Exponential decay
2. 18%
Step-by-step explanation:
0.8888888 = 8/9
2.8888888 = 26/9
-2.888888 = -26/9
What the hel you expect us to do all that for 5 kids points? Go ask you mom to do that for you. If you're asking US to do that, then it has to be 40 or 50 points.
6n−20=−2n+4(1−3n)
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
