Hey there!
3^3 * x^2 - 25 / 5
= 3^3 * 0.6^2 - 25 / 5
= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5
= 9 * 3 * 0.6 * 0.6 - 25 / 5
= 27 * 0.36 - 25 / 5
= 9.72 - 25 / 5
= 9.72 - 5
= 4.72
Therefore, your answer is: 4.72
Good luck on your assignment & enjoy your day!

Answer:
Step-by-step explanation:
he has 4.80 in dimes and quarters....dimes (d) are worth 0.10 and quarters (q) are worth 0.25
0.10d + 0.25q = 4.80
he has 6 more dimes then quarters
d = q + 6
====================
d = q + 6...so we sub q + 6 in for d, back into the other equation
0.10(q + 6) + 0.25q = 4.80
0.10q + 0.60 + 0.25q = 4.80
0.35q = 4.80 - 0.60
0.35q = 4.20
q = 4.20 / 0.35
q = 12 <====== there is 12 quarters
d = q + 6
d = 12 + 6
d = 18 <===== there is 18 dimes

We have:
As 5 has no perfect square factors, we have completely simplified this expression.
Answer:
y = 17.5
Step-by-step explanation:
Use the direct proportion equation, y = kx
Plug in the x and y values to solve for k
y = kx
35 = k(140)
0.25 = k
Then, plug in the k value and given x value into the equation, and solve for y
y = kx
y = 0.25(70)
y = 17.5
