Best ResponseYou've already chosen the best response.1`Shawn ran 5 miles more than Alex ran` if Alan ran x miles (some unknown number of miles), then how many did Shawn run? in terms of x

Best ResponseYou've already chosen the best response.1let's use actual numbers say Alan ran 7 miles how many miles did Shawn run?

Best ResponseYou've already chosen the best response.1how did you get that

Best ResponseYou've already chosen the best response.0cause it saids shawn ran 5 more miles than alan

jim_thompson5910

Best ResponseYou've already chosen the best response.1so you basically add 5 to whatever Alan has if Alan has x, then shawn has x+5

Best ResponseYou've already chosen the best response.1adding x to x+5 gives what?

Best ResponseYou've already chosen the best response.11apple + 1apple = 2apples so x+x = 2x

Best ResponseYou've already chosen the best response.1x + x+5 would turn into 2x+5, right?

Best ResponseYou've already chosen the best response.1`The sum of their distances is 19 miles` we just found the total distance to be 2x+5 equate the two 2x+5 = 19 then solve for x

Best ResponseYou've already chosen the best response.0x would be 7 @jim_thompson5910

jim_thompson5910

Best ResponseYou've already chosen the best response.1and x+5 would be x+5=7+5 = 12 so Alan ran 7 miles, Shawn ran 12 miles 7+12 = 19 checks out

Best ResponseYou've already chosen the best response.0but does this answer each question? 2 points: Choose a letter to represent your unknown value 2 points: Write an algebraic expression for each person using only one variable 2 points: Write an equation using the two algebraic expressions 2 points: Plug in each value from the domain into the equation 2 points: Find the distance Alex ra

Best ResponseYou've already chosen the best response.1how did you find that x = 7

jim_thompson5910

Best ResponseYou've already chosen the best response.1did you plug in various x values? or did you isolate x?

jim_thompson5910

Best ResponseYou've already chosen the best response.1so you did the `Plug in each value from the domain into the equation` step. Be sure to list every value from that set
