If bob jumps 15 additional times, the total number of his jumps will be 3 times what it was 3 jumps ago. bob has jumped times all together.
a) 12
b) 18
c) 21
d) 24

The answer is twelve  because three minus fifteen is twelve so the answer is twelve .

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
