Answer:

32, 36, 40

Step-by-step explanation:

8x + 9x + 10x = 108

27x = 108

x = 4

4 × 8 = 32 - 1st side

4 × 9 = 36 - 2nd side

4 × 10 = 40 - 3rd side

Li rode her bike 25% of the way to school. She rode 5 blocks. How many blocks does Li live from school?
Alenkasestr [34]

Answer:

20 Blocks

Step-by-step explanation:

First you would realize that 5 blocks is only 1/4 of the way to school because 1/4 is 25%

Next you should know that you just need to add 5 four times.

Lastly you would multiply 4*5=20

So therefore she lives 20 blocks from her school
