Vina has $4.70 in quarters, dimes and nickels in her purse. She has eight more dimes than quarters and six more nickels than qua

DanielleElmas [232]

Nickels (0.05): Q + 6

Dimes (0.10): Q + 8

Quarters (0.25): Q

Nickels + Dimes + Quarters = Total

0.05(Q + 6) + 0.10(Q + 8) + 0.25(Q) = 4.70

0.05Q + 0.30 + 0.10Q + 0.80 + 0.25Q = 4.70

0.40Q + 1.10 = 4.70

0.40Q = 3.60

Q = 9

Nickels (0.05): Q + 6 = (9) + 6 = 15

Dimes (0.10): Q + 8 = (9) + 8 = 17

Answer: Nickels = 15, Dimes = 17, Quarters = 9

Which rule deacribes the

Marysya12 [62]

Answer:

A. ${T_{-6,-2}}\circ {r_{x-axis}}(x,y)$

Step-by-step explanation:

We have that, ΔABC is transformed to get ΔA''B''C''.

We see that the following transformations are applied:

1. Reflection across x-axis i.e. flipped across x-axis.

Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.

2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.

So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.

Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.
