Answer:
16 miles
Step-by-step explanation:
<u>Step 1: Make an expression</u>
40% of what distance is 6.4 miles
x * (0.4) = 6.4
0.4x = 6.4
<u>Step 2: Divide both sides by 0.4</u>
0.4x / 0.4 = 6.4 / 0.4
x = 16
Answer: 16 miles
Answer:
2.)4n>(n/2)^2
3. (The problem isn't clear)
4.)n^2+2n-3=129
5.)n-5=171
Step-by-step explanation:
2.)
4n(four times the number) >(larger than) (n/2)^2 (half the number squared)
4.)
Sum=addition
n^2 (number squared) +2n (twice the number)-3=129
5.)
N(unknown number of pages) -5(amount of pages already read)= 171(the number of pages it took her to finish)
