Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Simply divide 3,475 by 5 to get 695 units per hour (you did not specify the distance unit, but i assume it might be miles per hour.)

Answer:
9 minutes
Step-by-step explanation:
First, you will want to add up all the time spent per problem.
3(9.5)+2(8.25)=45
Then, divide 9 from 45. 45÷5=9.
Therefore, she would have spent 9 minutes per problem.
V1=60. 60×t1=50×t2=S
V2=50
T=t1+t2=5. 5-t2=t1
60×(5-t2)=50×t2
300-60×t2=50×t2
300=50×t2+60×t2
300=t2×(50+60)
300=t2×110
300/110=t2
S=50×300/110
