r+b =12
r =2b (twice as many red as blue)
substitute r = 2b into r+b=12
2b + b = 12
3b =12
divide by 3
b=4
r = 2b
r=2(4)
r=8
There are 4 blue pencils and 8 red pencils
I’m sorry I don’t get what your asking?
{-1,0,1,2,3}.I think this is the answer of your question.
Answer:7+7
Step-by-step explanation:
i didn't know it was st.patrick's day
Since ∠1 and ∠2 are complementary...they add up to be 90°.
∠1 = (-2x + 54)
∠2 = (8x + 18) we add these two up
6x + 72 = 90 subtract 72 from both sides
6x = 18
x = 3 place the value of x into the ∠2 equation
(8x + 18) = 8(3) + 18 = 24 + 18 = ∠2 = 42°
