Samantha has $3.35 worth of dimes and
quarters. she has a total of 20 dimes and
quarters altogether. determine the
number of dimes and the number of
quarters that samantha has.

9 quarters and 11 dimes.

Step-by-step explanation:

Step 1-

d+q=20

.1d+.25q=3.35

Step 2-

d=20 - q

Step 3-

.1 (20 - q)+ .25q =3.35

.1 (20)- .1q+ .25q =3.35

2- .1q+ .25q =3.35

2+ (.25- .1)q =3.35

2+ .15q =3.35

Step 4-

2-2+.15q =3.35 -2

.15q =1.35

Step 5-

.15q/.15 =1.35/.15

Q=9

And since there are 9 quarters and 20 coins in total, there has to be 11 dimes left. Hope this helps!

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
