Answer:
Z = 8.8 Y = - 42
Step-by-step explanation:
Y = 2 - 5Z
Y = 5 - 47
2 - 5Z = 5 - 47
- 5Z = - 44
5Z = 44
Z = 8.8
Y = 2 - 5 (8.8)
Y = 2 - 44
Y = - 41
Y = 5 - 47
Y = - 42
Answer:
Bike alone = 39
Step-by-step explanation:
Given that:
Total number = n(T) = 100
Jog= n(J)
Bike = n(B)
Bike and jog = n(BnJ) = 21
Number who jog = 46
Jog alone = 46 - 21 = 25
Neither jog nor bike = 15
Let bike alone = x
Hence,
Jog alone + bike alone + jog and bike + none of the two = 100
25 + x + 21 + 15 = 100
x = 39

simplifying
we get 
Option B is correct.
Step-by-step explanation:
We need to simplify: ![\frac{\sqrt{4}}{\sqrt[3]{4}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B4%7D%7D%7B%5Csqrt%5B3%5D%7B4%7D%7D)
Solving:
![\frac{\sqrt{4}}{\sqrt[3]{4}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B4%7D%7D%7B%5Csqrt%5B3%5D%7B4%7D%7D)
We know that √ = 1/2 and ∛=1/3

Applying exponent rule: 

So, simplifying
we get 
Option B is correct.
