Answer:
x = 28
Step-by-step explanation:
ΔARP ≈ ΔCRD
42/x = 57/(10+x)
cross-multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 15x
28 = x
Answer:
the 3rd number line
Step-by-step explanation:
first of all, we know That the line starts from zero.
the inequation is n>0
the circle inside should be the hallow one because it's "greater" not greater than or equal to.
n>0 means that n is greater than 0.
in the number line, ( the 3rd one) n is going away from 0. it's going greater than 0.
that is why this is the correct answer.
I hope this clarified any confusion.

Step-by-step explanation:
Answer:
Step-by-step explanation:
(1) P = 5G
(2) G + P = 30
Substituting (1) into (2) gives:
G + 5G = 30
6G = 30
G =5
So there are 5 green pencils.
Now using that in (1) gives us P = 5 x 5 = 25
So there are 5 green pencils and 25 purple pencils.
