Answer:
The number of roses is 16
The number of lilies is 8
The number of orchids is 21
Step-by-step explanation:
Let
x-----> the number of roses
y-----> the number of lilies
z-----> the number of orchids
we know that
x=2y ----> y=x/2 ----> equation A
z=x+5 ---> equation B
x+y+z=45 ----> equation C
substitute equation A and equation B in equation C and solve for x
x+(x/2)+(x+5)=45
(5/2)x=45-5
(5/2)x=40
x=40*2/5
x=16 roses
<em>Find the value of y</em>
y=x/2 ----> y=16/2=8 lilies
Find the value of z
z=x+5 -----> z=16+5=21 orchids
therefore
The number of roses is 16
The number of lilies is 8
The number of orchids is 21
