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
Answer:
6m
Step-by-step explanation:
Area of a Square = Side × Side. Therefore, the area of square = Side² square units.
Area = Side²
A= (6m)²
A= (6m) x (6m)
A= 36m²
Square is a regular quadrilateral. It has all the four sides of equal length.
→ side=6m
