They do not intercept they are both straight horizontal lines one Where y is always equal to 4 and the other 5
So if you distribute 4 in the first parentheses, you get 12x+20y+8z.
Then you distribute 3 in the second parentheses. You'll get 3x-3z. That all equals 12x+20y+8z+3x-3z.
Now you have to start combining numbers with the same variable. Start with x. 12x+3x is 15x.
y has no other common variable, it's left alone.
8z-3z is 5z
All together now with the numbers in simpler form, the equation is 15x+20y+5z
Jenna's would be the right answer because when you distribute 5 in her answer you get 15x+20y+5z
179 and 180
consecutive numbers have a difference of 1 between them
let the 2 numbers be n and n + 1, then
n + n + 1 = 359
2n + 1 = 359 ( subtract 1 from both sides )
2n = 358 ( divide both sides by 2 )
n = 179 and n + 1 = 179 + 1 = 180
the 2 pages are 179 and 180
