Answer:
Willy Wonka
Step-by-step explanation:
Given data
it takes Charlie 45 minutes walking at 2.5 km/hr
speed = distance /time
distance= speed*time
distance= 2.5*45
distance= 112.5 km
it takes Willy Wonka 15 minutes walking at 3.5 km/hr
distance= speed*time
distance= 3.5*15
distance= 52.5 km
Hence Willy Wonka stays closer

Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 <u>70x - 63y = 462</u> {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6
Answer:
1st, keep value of x in 1st equation
Step-by-step explanation:
-6(-2y-1)+2y=48
12y+6+2y=48
14y=48-6
y=42/14
y=3
Now putting value of y in equation ii)
x= - 2y-1
x= - 2×3-1
x= - 6-1
x= - 7
Therefore, x= - 7
y=3
