I believe it would be 5/9
Multiply both sides by 19 to get w=171
Answer:
-7/15
Step-by-step explanation:
get red of the addition and subtract the two fractions
Answer:
The value of b = 1/36
As exponent decreases, each previous value is divided by 6
If the table was extended, the value of 6^-3 would be 1/216
Step-by-step explanation:
Given in the question a table containing power of 6
We will use negative rule of exponent to write the equivalent of negative power of 6
b^{-n}= 1 / b^{n}
we know that

so
= 1/6
and

So,

=

Answer:
1. y=kx
2. y=60
Step-by-step explanation:
y is directly proportional to x
y=kx
Find Constant K, when y=30 & x=6
Make K the subject of the formula first
K=y/x
K=30/6
k=5
When k is 5, x is 12, find y
y=kx
y=5×12
y=60
