----> equation A
-----> equation B
-----> equation C
substitute the value of z in equation B
substitute the value of y in equation A

In total
9+3+15=27 flowers
Answer:
60.16 m
Step-by-step explanation:
Let w = width of river
Using trigonometry :
The width, w of the river is can be calculated thus :
Tan θ = opposite / Adjacent
Tan 76 = w / 15
4.0107809 = w / 15
w = 15 * 4.0107809
w = 60.1617 m
Hence, width of the river is 60.16 m

Step-by-step explanation:
105.5x100/120=87.91so 100-88 = 22%
Answer:
125
Step-by-step explanation:
start with 10, and go backwards
10-6=4 4x100=400 400-150=250 250/2=125
checked answer:
125x2=250 250+150=400 400/100=4 4+6=10
