The expression 35 - m is used to determine the number of gallons left in the tank after m minutes.
<u>Solution:</u>
Given that a tank containing 35 gallons of water is leaking at a rate of gallon per minute.
Let "m" represent the number of minutes spent
Number of gallons left in the tank = initial amount of water present – leaked amount of water
Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.
Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute
Hence, the required expression is 35 – m
Does not do instrument and sport will be 2 (middle). Then you can go horizontol for does not play sport with the total being 7 (middle right) . 25 - 7 = 18 (top right). 18 - 16 = 2 (top left). 5 + 2 = 7(Bottom left)
Hope it helped because i cant really draw on it. :<
Distance = square root (24^2 + 7^2)
distance = square root (576 + 49)
distance = square root (625)
distance = 25
