Afarmer grew a watermelon that weighed 20 lb. from his experience with growing watermelons, he estimated that 95% of the watermelon’s weight is water. how much of the watermelon is water?

The water is 95% of the total weight of watermelon. Multiply 95% by the total weight to get the weight of the water.
water = 95% × 20
water = 0.95 × 20
water = 19

The weight of the water is 19 lbs

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
