Answer:
Part A: 3x-8=2+12
3x-8=14
3x=22
x=22/3
Part B:
Since we know that two angles are equal to 14 because they are vertical angles, we have 360 = 28+2y. Solving for y we get
332 = 2y
166 = y.
Answer:
5 inches per hour
Step-by-step explanation:
What we know: ones = 1, tens -->1x2 = 2, hundreds --> 2x2= 4, thousands --> 4x2 = 8.

To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
cost of apples is based on weight (lbs) so this is the rate, the bag is a flat fee.
y = mx + b ⇒ Cost = rate(lbs) + bag ⇒ C = 1.29(a) + 0.25
Answer: #3: c(a) = 1.29a + 0.25
