30 percent (calculated percentage %) of what number equals 18?
Answer:
Volume of the other section of tank B = (A-45)cm³
Step-by-step explanation:
Volume of tank A = Volume of tank B
One section of tank B = 45 cm³
Hence volume of the other section of tank B = (A-45)cm³
If you meant to say k=(-3)
First thing you would do is plug in the (-3) to a
Your equations would look like this:
k(a) = 4(-3) + 2
You would multiply 4 × -3, giving you -12.
k(a) = 12 + 2
Then you would add 12 + 2, giving you 14.
k(a) = 14
k(a) would equal 14.

Step-by-step explanation:
Given
and 
Then
Required
State the property
From the list of options, (d) answers the question.
This is so because:
Substitution property of equality states that
If 
then 
In other words, both can replace one another.
So if , then 2y + 1 can be substituted for x in
So:
becomes
<em>Hence, it is substitution property of equality</em>
