49.0%

Step-by-step explanation:

51 - 26 = 25

take the difference and divide it by the orginal number

25÷51 = 0.49019607843

then times that number by 100

(25÷51) × 100 = 49.0196078431

On a number line there are six spaces. On the first is the number 2, on the last space is the number 42, on the third space is x, solve for x.Thanks!

Answers

1st space is 2
6th space (last) is 42
in betwen that is 5 spaces to go
find distance from 2 to 42
42-2=40

40=5 spaces
divide 5
8=1 space
each space goes upby 8

2=1st space
2+8=2nd space
2+8+8=3rd space=18=x

x=18
