Lilly should re-estimate the original numbers to be smaller.
for example if she rounded to 10 and 20, she should go back and check and re-round to maybe 8 and 10
139 + 30d = 13 + 51d
139 - 13 = 51d - 30d
126 = 21d
126/21 = d
6 = d
now lets check..
139 + 30d = 139 + 30(6) = 319
13 + 51d = 13 + 51(6) = 319
so on day 6, they will both cost $ 319
Simplify the given expression as shown below
<h2>Therefore, the answer is 12x^5-15x^2</h2>
25 - 3x = M
Please correct me if I’m wrong !!
The answer is the 1st, 2nd and last one
