| - 6    - 4 |      | - 5    5 |              | - 6 + 5      - 4 - 5 |          | -1      - 9 |
| 6        0 | -   | - 4   -1 |     =       |   6 + 4     0 + 1 |    = | 10      1 |
| 6        4 |      | 6    - 4 |            |   6 - 6        4 + 4 |          | 0         8 |

Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d

algol [13]

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

$d_t=2d$

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

$Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days$

Now, we multiply the distance per day by the total number of days:

$Distance, D=2d\times 16\\\\=32d$

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

Simple.....

you have $\frac{18}{a} =7
$

to find what a is....simplify/multiply both sides....

$a* \frac{18}{a} =7*a$

simplifying it too....

18=7a

$\frac{18}{7} = \frac{7a}{7}$

$\frac{18}{7} =a$

Thus, your answer, C.
