a taxi charges $2 per mile and $1 per person. If a ride for 2 people costs $12, how many miles was the ride?
Aliun [14]

Answer:

5 miles

Step-by-step explanation:

$12 = ($2 per mile) (2 people)

$12 = $2 + $2m (m = mile)

subtract 2 on both sides to eliminate

$12 - $2 = $2 - $2 + 2m

$10 = 2m

divide both sides by 2 to eleminate m

$10 / 2 = 2m / 2

m = 5

Determine the value of a so that x1-3x3=-3 2x1+ax2-x3=-2 (i)unique solution(ii)no solution(iii)many solutions
Ad libitum [116K]

Answer:

(i)unique solution

Explanation:

We solve for x1 thus in the first equation:

x1-3x3=-3

x1-9=-3

x1=-3+9

x1= 6

We solve for a thus in the second equation:

2x1+ax2-x3=-2

2+a2-x3=-2

a2-x3=-4

a2=-4+x3

Diano4ka-milaya [45]

Answer:

Option B)  \frac{1}{6} Inches

Step-by-step explanation:

Maria's Centipede = 1\frac{1}{12} inches = \frac{13}{12} inches

Jerome Centipede = \frac{11}{12}

<u><em>To see how much longer Maria's centipede was than Jerome's, we'll subtract the two:</em></u>

=> \frac{13}{12} -\frac{11}{12}

=> \frac{13-11}{12}

=> \frac{2}{12} inches

=> \frac{1}{6} Inches
