Answer:
C. 4 X (3 + 8 – 6)
Step-by-step explanation:
3 + 8 = 11
11 - 6 = 5
5 x 4 = 20
Answer:
Step-by-step explanation:
Given expression is 
.
Now we need to find the cube root of given expression .
![\sqrt[3]{27a^{12}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27a%5E%7B12%7D%7D)
![=\sqrt[3]{3*3*3a^{4*3}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B3%2A3%2A3a%5E%7B4%2A3%7D%7D)
![=\sqrt[3]{3^3\left(a^4\right)^3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B3%5E3%5Cleft%28a%5E4%5Cright%29%5E3%7D)
![=\sqrt[3]{\left(3a^4\right)^3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cleft%283a%5E4%5Cright%29%5E3%7D)
Since cube root and cube are opposite operations of each other. So they will cancel each other.
Hence correct choice is the last choice .

Answer:
54kg
Step-by-step explanation:
Body weight = B
Tail weight = T
Head weight = H
Total weight = F
Use equation = B + T + H = F
We are told that T = 9kg, H = T + (1/3) x B, B = H + T
We have 3 equations and 3 unknowns, solve the system of equations to find W.
B = H + 9
H = 9 + 1/3 x (H+9)=9+H/3+3 --> 2/3 x H = 12 --> H = 18
B = 18 + 9 = 27
F = 18 + 27 + 9 = 54kg
Answer:
$55.80
Step-by-step explanation:
First, find how much Janet saved by finding 1/5 of 15.50:
15.50/5
= 3.1
Find how much Rob saved by multiplying 3.1 by 12:
3.1(12)
= 37.2
Then, find the total saved amount by adding them all together:
15.50 + 3.1 + 37.2
= 55.8
So, they saved $55.80 in total
