2.5 pounds of grain cost ======= $1.75
∴ 5.3 pounds of grain will cost ===== (5.3×1.75)/2.5 = $3.71
Write them out as a fraction then reduce them. If theyre the same then its proportional.
25/45 can be cancelled down to 5/9
15/27 can be cancelled down to 3/9
So no theyre not.
Answer:
30cm, 60cm
Step-by-step explanation:
Given data
Dimensions of the first rectangle
Length =10cm
Width =20cm
We are told that the dimensions of the second rectangle is gotten by multiplying the first rectangle by 3
Hence the dimensions of the second rectangle is
Length =10*3= 30cm
Width = 20*3= 60cm
Answer:
x>−6,x<−12
Step-by-step explanation:
Break down the problem into these 2 equations.
x+9>3x+9>3
-(x+9)>3−(x+9)>3
Solve the 1st equation: x+9>3x+9>3.
x>-6x>−6
3 Solve the 2nd equation: -(x+9)>3−(x+9)>3.
x<-12x<−12
Collect all solutions.
x>-6,x<-12x>−6,x<−12
Answer:
The distance cover by him walking back is 11.25 miles
Step-by-step explanation:
Given as :
Time for Janelle to spend on training = 5 hours
The running speed of Janelle = 9 mph
The walking back with 3 mph
Let The distance for running and walking is same i.e D miles
SO, Time = 
∴ 5 = 
+ 
Or, 5 × 9 = D + 3 D
Or, 45 = 4 D
∴ D = 
= 11.25 miles
Hence The distance cover by him walking back is 11.25 miles Answer
