Answer:
45
Step-by-step explanation:
As a first rough estimate: divide 390 by 10, obtaining 39.
Another reasonable approximation could be obtained by dividing 450 by 9 and 360 by 9, obtaining 50 and 40. Since 390 is roughly halfway between 360 and 450, estimate that the quotient is approx 45 (halfway between 40 and 50).
Answer:
$5 for one person to rent a locker
Step-by-step explanation:
Assuming the $18 is for one person, then two people it would be $36, since $18 + $18 = $36 and it's stated there's two people. If you subtract $36 from $46 you get $10, and since it's for two people you split it in half (so basically divide by 2) you get $5 for a locker.
Hope this helps!
Answer:
(1 , 3)
Step-by-step explanation:
y = -x + 4
y = 3x
=> -x + 4 = 3x
=> 4x = 4
=> x = 1
y = 3(1) = 3
Solution is (1 , 3)
No because the hundred place doesn't move.
