Answer:
6 and 12
Step-by-step explanation: Just think a it
The equation <u>6 + 9a = 51</u> can help find out how many adults were in the group.

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side
So

Multiply both sides by 2
2A = h(x+y)
Divide both sides by h
2A/h = x+y
Subtract y from both sides

or

Answer:
i will do it
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given

Required
Write, using scientific notation
The scientific notation is written in the form:
<em>Where n is an integer and </em>
<em />
To start with; <em>Represent the given number as fraction</em>

Represent the denominator as an exponent

This can be rewritten in form of:

Remember that:
<em>Where n is an integer and </em>
<em />
<em>This implies that; we need to adjust 2711 to a number between 1 and 10;</em>
This gives:

Write 1000 as an exponent

Apply law of indices


The question requires 2 numbers after the decimal point;
So, 2.711 will be approximated to 2.71

Hence;
<em></em>
<em> </em><em>is equivalent to </em>
<em></em>
