Answer:
The least common multiple would be 105.
Step-by-step explanation:
You would do list out the multiples for each. Or multiply
Since 3 x 30 is 90, and 3 x 5 is 15, This is 105
And since 5 x 20 is 100, and 5 x 1 is 5, This is 105 as well
Also, since 7 x 10 is 70, and 7 x 5 is 35, This is 105.
The LCM is 105

Here is a complete instructional answer
Answer:
75.5102040816%
Step-by-step explanation:
so the answer is 75% or 75.5%
37 x 100 =3,700
3,700 ÷ 49 =75.5102040816% so the actual answer is 75% bc they want you to round but its 6 and above to round up do you round down to 75%
<span>Let t
= travel time at 58</span>
<span>and
(6-t) = travel time at 49
distance at 58 + distance at 49 = 325.5 mi</span>
<span>
58t + 49(6-t) = 325.5
58t + 294 - 49t = 325.5</span>
9t+294
= 325.5
9t
=31.5
T =
31.5/9 = 3.5 hours at 58 mph
6-3.5
= 2.5 hours at 49 mph
<span> Check:</span>
58*3.5
= 203
49*2.5=
122.5
203+122.5
= 325.5
