Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7? StartFraction y over x EndFraction = StartFraction 7 over 10 EndFraction StartFraction y over x EndFraction = StartFraction 1 over 7 EndFraction x y = StartFraction 7 over 10 EndFraction x y = StartFraction 1 over 7 EndFraction

The answer is : 63explanation 60 times 0.05360+363

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
