D=dimes
q=quarters
d + q = 20
.10d + .25q = 3.05
d=-q + 20
.10(-q + 20) +.25q = 3.05
-.10q + 2 + .25 = 3.05
.15q + 2 = 3.05
.15q + 2 - 2 = 3.05 - 2
.15q = 1.05
.15q/.15 = 1.05/.15
q = 7
d + 7 = 20
d + 7 - 7 = 20 - 7
d = 13
Sally has 7 quarters and 13 dimes.
Hope this helps!
Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures

∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula



subtract 116 from both sides

Therefore ∠Q is equal to 64 degrees
Well if you use opposite operations then you will get
mg=6
to
g=6m
Answer: The first option, the one in orange.

This is the associative property.
Hope this helps, good luck on the test! :)
19.76/13 = $1.52
$1.52 x 20 = $30.40
