Ireally don't understand this! if anyone does ! : )

Statement: RUMH is rhombus
Reason: Given (It is stated in the question that RUMH is Rhombus)

Statement: RH=UM=HM=RU ⇒ This statement is saying that the length of side RH equals to side UM, HM, and RU
Reason: Because RUMH is a rhombus and all sides in a rhombus have equal length of sides

Statement: RUBM is rhombus
Reason: Given (the question does state RUBM is rhombus

Statement: RU=MB=RM=UB
Reason: RUMB is rhombus and all sides of a rhombus are have equal length

Statement: RH=UM=HM=MB=RM=UB
Reason: Statement 2 and statement 4 shares the side RU, and if RU has equal length with RH, UM, HM, MB, RM, and UB, then these sides are all equal

Statement: Triangle RHM = Triangle UMB
Reason: Since RH equals to HM and RM as well as to UM, MB, and UB, then the two triangles are formed by equal length of sides and therefore are congruent.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
