Answer:
new price= $2.40
Step-by-step explanation:
20%= 20/100= 1/5
$3.00/5= 00.60
1/5 of the price is being subtracted from $3.00
$00.60 is 1/5
3.00-.60= 2.40
(3x + 4)³ = 2197
Taking the cube root in this case is easier, although we can do it the extended way which is complicated.
![\sqrt[3]{(3x+4)^3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%283x%2B4%29%5E3%7D%20)
=
![\sqrt[3]{2197}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B2197%7D%20)
3x + 4 = 13
Now solve normally.
subtract 4
3x + 4 = 13
-4 -4
3x = 9
Divide by 3 to isolate 3

3 and 3 cancels out
x = 3
Answer:
y = 5x + 3
Step-by-step explanation:
The answer that belongs in the ? is 5.
In simplify the expression =
1.56 • 10^52 + 3.5 • 10^48
