Answer:
Step-by-step explanation:
If Elena walk 12 miles, and then 0.25 that distance
0.25=1/4
12*1/4=3 miles is 1/4 of the distance
she walked in total 12+3=15 miles
choice A =12+12*1/4
Answer:
See below
Step-by-step explanation:
Expand L side to get
4n -12 -2n < -10 + 2n simplify L side
2n -12 < -10 +2n subtract 2n from both sides
<u>-12 < -10 </u> <===== so the equation is true for ALL n

<span>To write 215% as a decimal you can approach the problem two ways. You can divide 215 by 100.
215/100 = 2.15
You can also move the decimal two places to the left 215.0 = 2.15
To write 2.15 as a fraction you will place 215 over 100. {215/100}. You will then want to write this fraction in it’s simplest form. The greatest common denominator is 5 so you will then divide the numerator and denominator by 5.
215/5 = 43
100/5 = 20
215/100 = 43/20
To write this fraction as a mixed fraction you would divide 43 by 20.
43 ÷ 20 = 2 with a remainder of 3
This is written as: 2 3/20</span>
