1. We assume, that the number 110.2 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 110.2 is 100%, so we can write it down as 110.2=100%.
4. We know, that x is 17.7% of the output value, so we can write it down as x=17.7%.
5. Now we have two simple equations:
1) 110.2=100%
2) x=17.7%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
110.2/x=100%/17.7%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 17.7% of 110.2

110.2/x=100/17.7
(110.2/x)*x=(100/17.7)*x - we multiply both sides of the equation by x
110.2=5.64971751412*x - we divide both sides of the equation by (5.64971751412) to get x
110.2/5.64971751412=x
19.5054=x
x=19.5054

now we have:
17.7% of 110.2=19.5054

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 5x + 7

g(x) = 3x - 1

<u>Step 2: Find</u>

  1. Substitute in functions:                                                                                    f(g(x)) = 5(3x - 1) + 7
  2. [Distributive Property] Distribute 5:                                                                 f(g(x)) = 15x - 5 + 7
  3. [Addition] Combine like terms:                                                                        f(g(x)) = 15x + 2

My house is 20 miles from yours, but on the map it is only 4 mm away. What is the scale of the map? O A Imm = 5 mi B. I mm = 20
dlinn [17]

\huge \bf༆ Answer ༄

Let's use Unitary method to solve the question ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:4 \: mm \rightarrow20 \: miles

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:1 \: mm \rightarrow(20 \div 4) \: miles

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:1 \: mm \rightarrow5 \: miles

Therefore, 1 mm corresponds to 5 mile according to the map.

so, correct choice is ~

\overbrace{  \underbrace{\underline{ \boxed{ \sf A }}}}
