Ed is on a road trip. He has already traveled 211 miles and is driving at a rate of 63 miles per hour. Which equation could be u

Marina86 [1]

Answer:

Option C is correct.

Step-by-step explanation:

Distance already traveled by Ed $=211$ miles

Also, Ed is driving at a rate of 63 miles per hour.

Distance $=$ Speed × Time

Distance traveled by Ed in $x$ hours $=63x$

Total distance traveled by Ed $=211+63x$

Also, total distance traveled by Ed is $638$ miles.

Therefore,

$638=211+63x$

Option C is correct.

kotykmax [81]

Answer:

Your answer is:

60= 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

96= 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

The second-highest number of factors are 48 and 80, containing 10 factors each.

The equations of two lines are x - 3y = 6 and y = 3x + 2. determine if the lines are parallel, perpendicular or neither.parallel

Mice21 [21]

Start by converting x - 3y = 6 into slope-intercept form:
x - 3y = 6
Subtract x from both sides:
-3y = -x + 6
Divide both sides by -3:
y = (1/3)x - 2
Now compare both equations:
y = (1/3)x - 2
y = 3x + 2
They don't share anything perpendicular or parallel equations would share, so therefore they are neither.

Hope this helps! :)
