$1 per person

There are 2 people

Subtract 2 from 12

12-2= 10

$2 per mile

10÷2= 5

The taxi driver drove 5 miles.

Hope this helped! :)

Write a multiplication equation that represents the question: how many 3/8 are in 8?

goldenfox [79]

Answer:

8

Step-by-step explanation:

$\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8}$

$\frac{3}{8}$ × 8

= 3

In algebra:

$\frac{3}{8}$ × y = 3

y = 3 ÷ $\frac{3}{8}$

y = 8

2. A supermarket display consists of boxes of cereal. The bottom row has 27 boxes. Each row has four fewer boxes than the row be

tresset_1 [31]

Answer:

Step-by-step explanation:

) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference

6th row = 23 + (6 - 1) x -3

= 23 + (5) x -3

= 23 + (-15)

= 8 - number of boxes in the top row.

b) Sum = N/2[2F + (N - 1) x D]

= 6/2[2*23 + (6 - 1) x -3]

= 3 [46 + (5) x -3 ]

= 3 [46 + -15 ]

= 3 [ 31 ]

= 93 - total number of boxes in the entire display.
