Your brother is riding in a hot-air balloon over a lake. From an altitude of 4000 feet,
he throws a rock straight down toward the
water. When the rock leaves his hand, its
speed is 30 feet per second. How long will
it take the rock to hit the water?

5x+2x=49

7x=49

x=7. 35 apples

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
