Which property should Remus use to solve the equation
below?
7q=49

Division Property of Equality

Step-by-step explanation:

To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.

answer: finding the extract measurements and knowing the points

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
