Answer:
22.25 ft long
if you add 10.5 with 11.75 you'll get 22.25
Each interior angle = 540/5= 108
Every other number from the first, 3rd, 5th, ..etc it adds 2 for the next number.
For the 2nd, 4th, 6th, etc term, its supposed to be 90, 78, 65, 51?
If so, It started with -12 then -13 after that -14 find the next term, all you need to do is to -15 to the current number, which is 51. then you get 36
Answer:
They sold
20 Roses and 20 Carnations
Step-by-step explanation:
The total sales of 40 flowers is $100 not $10 as in the question
Roses=$3
Carnations=$2
Total flowers sold=40
Total sales=$10
Let Roses=r
Carnations=c
c+r=40. (1)
3r+2c=100 (2)
From (1)
c=40-r
Substitute c=40-r into (2)
3r+2c=100
3r+2(40-r)=100
3r+80-2r=10
r=100-80
r=20
Substitute r=20 into (1)
c+r=40
c+20=40
c=40-20
=20
c=20
r=20
Check:
3r+2c=100
3(20)+2(20)=100
60+40=100
100=100
