Answer:
They represent am unknown number
Answer:
96 minutes or 1 3/5 hours
Step-by-step explanation:
To get this answer properly , we shall be converting any of the time fraction to minutes
The total time taken is 3 4/5 hours
1 hour is 60 minutes, 3 hours is 3 * 60 = 180 minutes
4/5 hours is 4/5 * 60 = 48 minutes
Total travel time is 48 + 180 = 228 minutes
Walking, he did for 2/5 hours = 2/5 * 60 = 24 minutes
Riding on a train took 1 4/5 hours; that would be 60 minutes plus 4/5 * 60 = 48 minutes ; a total time of 108 minutes
Time spent on walking and on train would be 108 minutes + 24 minutes = 132 minutes
The time spent on train would thus be 228 - 132 = 96 minutes = 60 + 36 minutes = 1 hour + 36/60 = 1 hour + 3/5 hours = 1 3/5 hours was spent on the train
If you would like to evaluate g(20) * f(6), you can do this using the following steps:
f(x) = x^2 + 1
g(x) = 3x + 1
g(20) + f(6) = (3 * 20 + 1) + (6^2 + 1) = 61 + 37 = 98
The correct result would be 98.
The total amount of x values of dimes and q values of quarters is equal to 6.35. From the given, the number of dimes may also be expressed as, 3q + 3. The equation that best represent the given is,
(3q + 3)(0.1) + q(0.1) = 6.35
Answer:
x = -4 / 3
Step-by-step explanation:
step 1. simplify 4x2 to 8
8+6x=0
step 2. subtract 8 from both sides.
6x = -8
step 3. divide in both sides by 6.
x = - 8 / 6
step 4. simplify 8/6 to 4/3.
x = -4 / 3
