Answer:
12 miles = 72 minutes
1/6 miles = 1 minute (divide both side by 72)
15 miles = 90 minutes (multiply both sides by 90)
Step-by-step explanation:
answer - 15 miles
Answer:
0
Step-by-step explanation:
4x-y=-20
Subtract 4x and bring it to the other side
-y=-4x-20
Divide by -1
Y= 4/1+20/1 which = y=4x+20
Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
Answer:
28
36
40
44
just do the number +1 and ×4
