Answer:
21/50 or 21:50
Step-by-step explanation:
1km = 1000m
That means one meter is equal to 1/1000 of a km.
420 meters is 420/1000 of a km which is equal to 42/100 = 21/50 or 21:50
Is it right?

Answer:
(x-6)(x+2)
Step-by-step explanation:
Use FOIL to check if the factors work.
x * x = x²
(x * 2) + (x * -6) = 2x - 6x = -4x
-6 * 2 = -12
out of every 13 will most likely be an ace.
1.1x+1.2x-5.4=-10
11/10x+12/10x-54/10=10
11x/2.5+2^2-1*3/5x-3^3/5=-10
(11x)+2(2*3x)+2(-3^3)/2*5=-10
11x+2(6x)+2(-27)/2*5=-10
11x+2*6x-2*27/2*5=-10
11x+12x-54/2*5=-10
23x-54/2*5=-10
23x-54=-100
23x=-46
23x/23=-46/23
x=-2*23/23
x=-2
Answer:

Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces



Lastly, add the leftover to get the actual length of the wood

Substitute 50w for Result and 20 for Leftover

<em>Hence, the length of the wood is 50w + 20</em>
