Answer:
35 is the answer of that problem
Answer:
9 and 21
Step-by-step explanation:
<u>setting up the equation</u>
let x and y represent the two numbers
this means that x + y = 30
x - y = 12
<u>using substitution to solve</u>
if x - y = 12, that can be rearranged to x = y + 12.
substitute x = y + 12 into x + y = 30
you get (y + 12) + y = 30
simplify
2y + 12 = 30
2y = 18
y = 9
plug this into the original equation x + y = 30. this would be
x + 9 = 30
x = 21
the numbers are 21 and 9.
720 ways... if you divide six into all answers, 720 is the only rational number
My day was actually pretty good. I went shopping for some important stuff, and when to go eat breakfast, i came home packed lunch, and got to do homework, haven’t stopped since.
Answer: See steps and explanation below. The value 5 makes the equation true.
9(3x - 16) + 15 = 6x - 24 Distributive Property
27x - 144 + 15 = 6x - 24 Combine like terms
27x - 129 = 6x - 24 Subtract 6x from both sides
21x - 129 = -24 Add 129 to both sides
21x = 105 Divide both sides by 21
x = 5 Answer!
