Answer:
15/8
Step-by-step explanation:
tan 2θ = 2 tan θ / (1 − tan² θ)
tan 2θ = 2 (3/5) / (1 − (3/5)²)
tan 2θ = (6/5) / (1 − 9/25)
tan 2θ = (6/5) / (16/25)
tan 2θ = (6/5) × (25/16)
tan 2θ = 15/8
Answer:
x<-3
Step-by-step explanation:
-2(x+1)+6x<-14
Distribute
-2x-2 + 6x < -14
Combine like terms
4x -2 < -14
Add 2 to each side
4x-2+2 < -14+2
4x < -12
Divide by 4
4x/4 < -12/4
x<-3
8(5) - 4y = 39
40 - 4y = 39
-4y = -1, y = 1/4
Solution: y = 1/4
Answer:
There will be $22,800 left after 6 years
Step-by-step explanation:
4% every year after 6 years = 24% be taken out of 30,000
24% of 30,000 = 7200 so you'll have 22,800 left.
I used to shovel snow for $5 an hour.
If ' t ' was the number of hours I spent shoveling somebody's driveway,
then ' 5t ' was the number of dollars he owed me for the job.
' t ' didn't even have to be a whole number. It worked fine with any number.
