Answer:
number of Roses = 60
number of carnations = 80
number of Lilies = 75
Step-by-step explanation:
Roses = $3.00
carnations = $1.00
Lilies = $2.00
Total order = 215
Let
x = number of Roses
y = number of carnations
z = number of Lilies
There are 15 more lilies than roses.
z = x + 15
The total of the order came to $410.00.
x + y + z = 215
3x + y + 2z = 410
substitute z = x + 15
x + y + x + 15 = 215
3x + y + 2(x+15) = 410
2x + y + 15= 215
3x + y + 2x + 30 = 410
2x + y = 215 - 15
5x + y = 410 - 30
2x + y = 200 (1)
5x + y = 380 (2)
Subtract (1) from (2)
5x - 2x = 380 - 200
3x = 180
Divide both sides by 3
x = 180/3
= 60
x = 60
Recall
z = x + 15
z = 60 + 15
= 75
z = 75
Substitute the value of x into (1)
2x + y = 200
2(60) + y = 200
120 + y = 200
y = 200 - 120
= 80
y = 80
Therefore,
x = number of Roses = 60
y = number of carnations = 80
z = number of Lilies = 75
Answer: so if you Simplify it will be 6/36 hope it helps
Step-by-step explanation:
The product of constant factors 9 and x + 7
ArcCos (.75) = x = 41.409
plug the x value into sin x and solve it
You will find that sin x = 0.66
Hope this helps
Hey there!
1/5 ÷ 1/3 = 3/5
Hope this helps!
