Question

5. The sum of two integers is - 450. If one integer is -327, find the other.
6. A well has 15 steps inside it. The water level is at the ninth step. A frog is sitting on the topmost
step. i.e., the first step.
a. The frog jumps 3 steps down and then jumps 2 steps up. In how many jumps will it
reach the water level?
b. After reaching the water level, the frog jumps 4 steps up and then 2 steps down in every
move. In how many jumps will it return to the topmost step?​

Answer 1

Step-by-step explanation:

(5)let the other integer is x.

one integer =-327

The sum of two integers =-450

or, -327+x=-450

or, x=-450+327

or, x=-123

The other integer is -123.

(6)A well has 15 steps inside.

the water level at the 9th step

the frog is sitting on the 1st step.

(a) the frog jumps 3 steps down i. e the frog reaches at the 4th step.

then jumps 2 steps up so reach at 2nd step.

reaching step =9

frog covers =2

the steps required to reach the water level =9-2=7

so 7steps required.

(b) after reaching the water level =9th step

the frog jumps 4 steps up =5th step

then jumps 2 steps down =-2nd step

the frog reaches at =5-(-2)=7th step

to reach the top most step =1st step

the steps required for reaching at the 1st step =7-1=6

so after 6 steps the frog reaches at the top step.
