Answer: 20 miles
Step-by-step explanation:
From the question, we are informed that Avis truck company charges $20 plus $2 per mile and that Budget truck company charges $3 per mile.
Let the number of miles that the charge will be the same for both companies be represented by x. This can then be used to form an equation as:
20 + 2x = (3 × x)
20 + 2x = 3x
3x - 2x = 20
x = 20
The charge will be thesame at 20 miles
Solve for x in the first equation:
X -2 = 1/3
Add 2 to both sides:
X = 2 1/3
Now replace x in the second equation:
2 1/3 ^2 - 4(2 1/3) + 4
5 4/9 - 9 1/3 + 4 = 1/9
Answer is B.
50 square meters is equal to 77500 square inches
<em><u>Solution:</u></em>
Given that we have to convert 50 square meters to square inches
<em><u>Use the following conversion factor</u></em>
1 meter is equal to 39.3701 inch
That is,
<em><u>Now frame the conversion factor for square meters to square inches</u></em>
<em><u>Now convert 50 square meters to square inches</u></em>
Muliply both the sides by 50
Thus 50 square meters is equal to 77500 square inches
