First use distributive property:
2(3n + 4) - 2(2n + 5)
6n + 8 - 4n - 10
Group like terms:
6n - 4n + 8 - 10
Add like terms:
2n - 2
Answer:
The null hypo would be the difference is greater than 0
so the alternate hypothesis would be less than or equal to 0
H1: µd ≤ 0
20x + 25 = 165
x represents the number of bags. You can solve the equation to make sure the answer is 7.
20x + 25 = 165
Subtract 25 from both sides.
20x = 140
Divide 20 off of both sides.
x = 7
Answer:
see below
Step-by-step explanation:
342 m/s * 1.09361329834 yd /m * 1 mile / 1760 yards = .21251 mi/s
1500 mi / hr * 1609.344 meters / mile * 1 km / 1000 m = 2414 km/hr
Answer:
Angle R is 99 degree
Angle Y=48 degrees
Angle T is 33 degrees
Step-by-step explanation:
Let angle T be x
Angle R will be 3x
Angle Y will be x+15
Total=x+3x+x+15=5x+15
5x+15=180
5x=165
x=165/5=33
Therefore, angle T is 33 degrees, angle Y=15+33=48 degrees and angle R=33*3=99 degrees
