Parallelogram with vértices (-10,7) , (7,-4), and (-10,-2)

kkurt [141]

So basically in any paralellogram you have 2 pairs sides that are equal length and that are paralell to each other

hmm

we look at them that we have and look for matches

the only match we got is (-10,7) and (-10,-2)
means that one side is from (-10,7) o (-10,-2) and is 9 units long goint up
that (7,-4) must be the other poinr of the other side
since -4<-2, the missing point must be 9 units up from (7,-4)
9-4=3

(7,5) is the missing point

Steve has three times as many quarters as half-dollars. The coins total $13.75. How many total coins does he have, how would you

statuscvo [17]

Hello,
Let assume x the number of half-dollars3x is the number of quarters.
The coins total $13.75.
$0.50 *x+ 0.25 *3x=13.75\\

\Rightarrow\ \dfrac{x}{2}+ \dfrac{3x}{4}=13.75\\

\Rightarrow\ \dfrac{2x}{4}+ \dfrac{3x}{4}=13.75\\

\Rightarrow\ \dfrac{5x}{4}=13.75\\

\Rightarrow\ 5x=4*13.75\\

\Rightarrow\ 5x=55\\

\Rightarrow\ x=11\\

$

11 is the number of half-dollars

33 is the number of quarters.
