54 boo . Divide 189 by 7 then multiply by 2 which is 54
milli = 1/1000, so milligams = 1/1000 of a gram.
So:
2000 milligrams * 1 gram/1000 milligrams = 2 grams.
Complementary angles add up to 90 degrees.
The complement of 57 is (90 - 57) = 33 degrees.
Answer:
I believe the answer is B
Step-by-step explanation:
Part A answer: 2x+5. x is the number of miles driven.
Part B answer: $305. Plug in 150 for x, and the equation is 2*150+5=x, x being your answer that you are looking for. Do the Order of Operations, which is PEMDAS (Parenthesis, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right.) So in other words, do 2*150 first, and you get 300. Now your equation is 300+5=x. Add 300+5, and you get 305=x. So your answer is $305.
