Can some one help pls. ill give 10points

1.1n

0.6p

0.3b

Step-by-step explanation:

Simplifying Like terms

Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.

Terms like 5xy, -6xz, are not similar because they have different letters of powers.

The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus

1.6n - 0.5n = 1.1n

Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:

0.9p - 0.3p = 0.6p

Finally:

b - 0.7b = (1 - 0.7)b = 0.3b

Results:

1.1n

0.6p

0.3b

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !
