2.10 + 0.80m = 11.70
0.80m = 11.70 - 2.10
0.80m = 9.60
m = 9.60 / 0.80
m = 12.....she traveled 12 miles

Answer:

Given,

The fixed charges = $ 2.10

Additional charges per miles = $ 0.80,

Thus, the additional charges for x miles = 0.80x dollars,

So, the total charges for x miles = Fixed charges + additional charges

= 2.10 + 0.80x

According to the question,

2.10 + 0.80x = 11.70

Which is the required equation,

Subtract 2.10 from  both sides,

0.80x = 9.6

Divide both sides buy 0.80

x = 12

Hence, she travelled 12 miles.

Nat2105 [25]

<em><u>Question:</u></em>

Hector has a floor plan showing his new house. On the floor plan, his bedroom is 3 inches wide and 3 1/2 inches long. The scale of the floor plan is 1/4 inch = 1 foot. What is the actual length of Hector’s room?

<em><u>Answer:</u></em>

The actual length of Hector room is 14 foot

<em><u>Solution:</u></em>

Given that, On the floor plan, his bedroom is 3 inches wide and 3\frac{1}{2} inches long

<em><u>The scale of floor plan is given as:</u></em>

\frac{1}{4} \text{ inch} = 1 \text{ foot }

Therefore,

1 \text{ inch } = 4 \text{ foot}

To find: Actual length of floor

From given question,

length = 3\frac{1}{2} \text{ inches}

Converting the mixed fraction to improper fraction,

length = \frac{2 \times 3 + 1}{2} = \frac{7}{2} \text{ inches }

Since, 1 inch = 4 foot

\frac{7}{2} \text{ inches } = \frac{7}{2} \times 4 \text{ foot } = 14 \text{ foot }

Thus actual length of Hector room is 14 foot
