If 6 men build a wall in 15 days then
1 man would build a wall in 2.5 days (found by dividing 15 by 6)
To find in how many day 9 will, we multiply 2.5 times 9
2.5*9= 22.5
ANSWER:
It will take 22.5 days
Y - x = 6
y + 2x = 57
2y - 2x =12
y + 2x = 57
∴3y = 69
y = 23
23 - x = 6
-x = -17
x =17
large van = 23
small van = 17
Answer:
B. 
Step-by-step explanation:
Find the missing length by subtracting 5^2-3^2 to get 4^2.
Then do 4^2+7^2 to get 65
Step-by-step explanation:
Given line is 6x+3y=15
Slope of the given line (m)=-x/y
=-6/3
=-2
let slope of the line perpendicular to the given line be m'.
Condition of perpendicularity,
m×m'=-1
-2×m'=-1
m'=-1/-2
m'=1/2
