Best ResponseYou've already chosen the best response.0how do i solve this system: 5x+2y =7 x/2 + y/6 = 3/2 i have been trying to solve this but can't get it right, could you show me the steps!

Best ResponseYou've already chosen the best response.0I did that one on your other post, do you see it?

Best ResponseYou've already chosen the best response.0solve for y in the top: y = 5x/2 +7/2 plug it into the bottom equation: x/2 + (5x/2 +7/2)/6 = 3/2 Solve for x: x/2 5x/12 +7/12 = 3/2 6x/12 5x/12 +7/12 = 18/12 6x 5x +7 =18 11x = 11 x=1 Now that we have a solid number for x; plug it into the equation we found for y: y = 5(1)/2 +7/2 y= 5/2 + 7/2 y= 12/2 = 6 Double check for accuracy :)

Best ResponseYou've already chosen the best response.0ok thanks i really appreciate it, i have one other... completing the square t^2 9t_______ it says to first complete trinomial ____________________________ the then (_________________________)^2 bionomial squared...

Best ResponseYou've already chosen the best response.0for the first question... i was taught to plug 0 in.... how did you get 7/2 ....

Best ResponseYou've already chosen the best response.0Yes, to complete the square we need to find a term whose product adds up to (9); which is just (9/2)^2.

Best ResponseYou've already chosen the best response.0To solve for y: subtract (5x) from both sides: 2y = 5x + 7 now divide everything by (2): (2/2)y = (5/2)x + (7/2) y = (5/2)x + (7/2)

Best ResponseYou've already chosen the best response.0ok got that... and then this step confuses me Solve for x: x/2 5x/12 +7/12 = 3/2 6x/12 5x/12 +7/12 = 18/12

Best ResponseYou've already chosen the best response.0(t(9/2))^2 = (t(9/2)) (t(9/2)) = t^2 9 + 81/4

Best ResponseYou've already chosen the best response.0with the 6 on the bottoms and turned to tweleve why did you multiply

amistre64

Best ResponseYou've already chosen the best response.0To solve for x: we need to get all the fractions having the same denominators. The common denominator is 12: x/2 needs to be multiplied by 6/6 to get a 12 on the bottom: 6x/12 5x/12 already gots a 12 +7/12 already gots a 12 3/2 needs to be multiplied by 6/6 to get 12 on bottom: 18/12 Now because everything has a 12 on the bottom, we can toss the 12 out to clean up the equation: 6x 5x +7 = 18

Best ResponseYou've already chosen the best response.0but what happens to the 6 on the bottom of the 2nd fraction...

Best ResponseYou've already chosen the best response.0i see it: we solved for y to get: y = 5x/2 +7/2 The second equation has the term: y/6, so plug in what you found out about "y" to get: (5x/2 +7/2)/6 when we divide the 6 thru we get: (5x/2)/6 and (7/2)/6 the 6 actually multiplies to the bottom number, the 2. so that the denominators become 12. Does that make sense? I can try explaining it another way if you like

Best ResponseYou've already chosen the best response.0ok i understand that now, so then once i have those answers (x/2) (5x/2)/6 (7/2)/6 = 3/2 what am i doing to get twelve? becaues isn't (7/2)/6 technically .58

amistre64

Best ResponseYou've already chosen the best response.0let me try it this way, cause fractions are terrible in this format. top: (5x)(1) +(7)(1) = 5x +7 bottom: (2) (6) (2)(6) = 12 12 How does that look? :)

Best ResponseYou've already chosen the best response.0more confusing i have wrritting out fine... with the fractions over 6 but don't get what i am doing if i have 7/2 over 6 that equals .58

amistre64

Best ResponseYou've already chosen the best response.0To divide fractions; flip the bottom one over and multiply across. (7/2)/(6/1) is the same as (7/2)(1/6) = (7/12)
