Bob has 19 Pokemon cards. Suzy has an unknown number. Joe has 1/4 of the number that Bob+Suzy have. There are 35 cards altogether. How many does Suzy have? I need Help my friend gave me this question and I don't know how to solve It Please Help... I'll give a Medal and Fan you!! <3
And also can someone show me how to solve it step by step?? <3
the way id do it...make an equation for the sentence "Joe has 1/4 of the number that Bob+Suzy have." call joe j and suzy x 1/4(19+x)=j and in total they have 35 cards so 19+j+x=35 now we have two equations
j is solved for in the first equation so we can take that and plug it into the second one for j 19+1/4(19+x)+x=35 now can you solve for x?
yes I can solve :)
is 19 + 1/4 = 19 1/4? @CalebBeavers
okay I don't get it?
The 1/4 is being multiplied, distribute it into the parentheses
Multiply straight across 19/4 and also multiply it by the x so we have 19+(19/4)+(1/4)x+x=35
Now just combine like terms and isolate x 19+(19/4)+(5/4)x=35 95/4+(5/4)x=35 (5/4)x=45/4 x=(45/4)*(4/5)
/Ok Let B = Bob, J = Joe and S = Suzy B = 19 S = x J = (1/4) (x+19) Together they have 35: 19+x+(1/4)(x+19) = 35 19 + x + x/4 + 19/4 = 35 and solve for x :) : 5x/4 + 95/4 = 35 5x/4 = 35 - 95/4 5x/4 = 45/4 5x = 45 x = 9 Then just substitute the value for x for each person: we get that x= 9 So S = x = 9
