Answer:
72
Step-by-step explanation:
If the rates d and c are flowers per day, we have ...
150/d = 120/c
d -c = 18
__
Multiplying the first equation by cd/30, we have ...
5c = 4d
Multiplying the second equation by 4 gives ...
4d -4c = 72
Adding these equations together, we get ...
5c +4d -4c = 4d +72
Simplifying and subtracting 4d leaves ...
c = 72
Charlie can plant 72 flowers per day.

-.14*.12 = -.0168
.14*.12 = .0168
-.0168-.0168=-.0336

Answer:
x = 94°
Step-by-step explanation:
The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is
( arc CD + arc AB ) = 82°
Multiply both sides by 2 to clear the fraction
CD + AB = 164°, that is
x + 70 = 164 ( subtract 70 from both sides )_
x = 94°
