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.
Answer:
x = -10
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
Given
9x - 3 - 8x = 7 - x , that is
x - 3 = 7 - x ( add x to both sides )
2x - 3 = 7 ( add 3 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Answer: 793 mi/h
Step-by-step explanation:
We have the following data:
is Earth radius at the 40th parallel of north latitude
is the Earth's angular velocity (toward the east)
is the Jet's angular velocity (toward due west)
And we need to find the Jet's speed , which is calculated by:
