Mathematics
1 answer:
PSYCHO15rus [73]3 years ago
5 0

Answer:

b = 54 cm

Step-by-step explanation:

We can use proportions if the shapes are similar

Take the same side lengths over each other.

81   cm            b cm

----------- = --------------

24  cm           16 cm


Using cross products

81 *16 = 24*b

Divide each side by 24

81*16/24 = 24b/24

54 =b

3 + 1.75m

This represents 1.75 per mile plus a one time 3 charge.

Another way this can be written is

(1.75m + 6) - 3

This is a less efficient way, but represents the same. It is 1.75 per mile, this is plus 6, therefore we add the -3 outside the parenthesis so it evens out to +3 as the base charge.

Example: Lets say its 3 miles.

3 + 1.75 (3) = 8.25

(1.75 (3) + 6) - 3 = 8.25
