So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.

ss7ja [257]
I think you doubled them

ratio of dogs to cats=3:2

30 animals total

3+2=5 units
30=5unit
divide by 5
6=1unit

dogs=3 unit
6=1unit
times 3
18=3unit=dogs

18 dogs

Assuming that the order is
ok so
distance from greenvile to parker=29
distance from greenvile to hadley=?

distance from hadley to greenvile is 12 and 1/2 less than distance between parker and greenvile means
?=-12 and 1/2+29
add
-12 and 1/2+29=6 and 1/2


?=6 and 1/2 miles
