I am working with congruent quadrilaterals and I do not understand it. I need to figure a\out the value of x and y 4x 28 ___= ___ 28 8y+2
Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!
For something to be explicitly equal 4x=28 and 28=8y+2. At least, thats how it works in linear algebra. Without that fact, you can't solve 2 unknowns with one equation.
Amistre, am I right?
yes you are
as far as i can tell ;)
it can be solved; but it creates a line
I figure this solves out like partial fraction decomp. Linear algebra ftw? haha
I made a mistake the number above the 8y+2 should be 34 not 28
All that does is change my first equation to 4x=34
cross multiply; or try a 0y in the top
4x(8y+2) = 34 (28)
ok
32xy +8 = 952 32xy = 952 - 8 xy = 944/32 = 29.5
now if you know x or y; you can determine the missing peice
im not sure if solving for y and subing it in is a good idea or not
looks to be the same regardles
I am so confused
cant read your mind; try to tell us why?
did you type in in right?
perhaps x = 34/4 and y = 26/8
Thank you
itd be better if we could see the problem :) but you are welcome
It gives me two shapes both look similiar. across the top of one is 4x and along the side it is 34. The next shape across the top is 28 and along the side is 8y+2. They are congruent and I am supposed to find the value of x and y.
4x = 28 x = 28/4 x = 7 34 = 8y+2 32 = 8y y = 32/8 = 4
equate sides and solve for the variable
Thank you
