Answer:
Equally likely
Step-by-step explanation:
A coin has two sides, heads and tails, so if you flip it, you have a 50% chance to get heads and a 50% chance to get tails. 50% - 50% is an equal ratio, therefore having an equal chance of likelyhood to get heads.
Answer:
40 miles
Step-by-step explanation:
Let's set <em>x</em> to the number of miles driven, and <em>t</em> to the number of hours it took to drive.
We know that 40<em>t</em> is equal to <em>x</em>.
We also know that 40<em>t</em> is equal to 30(<em>t</em> + 1/3).
Solve for t:
40t = 30(t+1/3)
40t = 30t + 10
Subtract 30t from both sides:
10t = 10
Divide 10 from both sides:
t = 1
40t = 40 x 1 = 40 miles
Solve the system
<span>y = x + 4
y = 3x + 6
Note that both equations have been solved for y. Thus, you can set y = y, or
x+4=3x+6. Simplifying, -2 = 2x, or x = -1.
Another way to look at this would be x + 4 = 3x + 6.</span>
