Answer:
The number of big pictures are 49 and number of small pictures are 48 .
Step-by-step explanation:
Let us assume that the number of big pictures are x .
Let us assume that the number of small pictures are y .
As given
Big pictures are 56$ each small ones are 34$.
97 were sold at the total of $4,376.
Equations becomes
x + y = 97
56x + 34y = 4376
Multiply x + y = 97 by 56 and subtracted from 56x + 34y = 4376 .
56x - 56x + 34y - 56y = 4376 - 5432
-22y = - 1056
22y = 1056
y = 48
Put value of y in the equation x + y = 97
x + 48 =97
x = 97 - 48
x = 49
Therefore the number of big pictures are 49 and number of small pictures are 48 .
Answer:
Dilate Circle A by a scale factor of 3
Step-by-step explanation:
Circle A has a radius of 3, Circle B has a radius of 9. By dilating Circle a by a scale factor of 3, it will make it the same size as Circle B, showing that the two circles are similar.
Rotating and reflecting does nothing because both circles are in the same quadrant and rotating a circle does nothing to the placement.
Translating the circle (x+3, y-2) does not put it in the same place as circle B.

1) F + (N - 1)*D=Nth Term, where F=First term, D=Common difference and N=Number of terms.
-1 + (8 - 1)*D =20, solve for D
-1 + 7D = 20
7D = 20 + 1
7D =21 divide both sides by 7
D = 21 / 7
D = 3 Common difference
2)
(F + L) / 2*N, where F=First term, L=Last term and N=Number of terms.
Sum = (-7 - 115) / 2*13
Sum =( -122 / 2) * 13
Sum = -61 * 13
Sum = -793
