Answer:For this case, the first thing we must do is define variables.
x: amount of time Miguel uses to complete the task.
y: amount of time Maria uses to complete the task.
We write the system of equations:
x + y = 60
y = (1/2) x
Solving the system we have:
x = 40 minutes
y = 20 minutes

Answer:
The bus will travel 720 miles in 15 hours.
Step-by-step explanation:
As you know that the bus traveled 336 miles in 7 hours and it traveled the same number miles each hour, you can divide the amount of miles it traveled by the number of hours to determine the amount of miles per hour:
336/7=48
Now, you can multiply the number of miles the bus traveled each hour for 15 hours:
48*15=720
According to this, the answer is that the bus will travel 720 miles in 15 hours.
Answer:
y=2x
Step-by-step explanation:
y = kx is the format of the graph we are looking for (as told in the instructions) where k is the variable we are supposed to find (like y = x, y=2x, y=3x, etc)
Note that as x increases by 1, y increases by 2. We can see that by writing a table of the points of points that the line given intersects (picture below). We can see that by the values of the x-axis and the y-axis. Why does this happen? This is because y =2x for each value of x. We notice that in our table.
Therefore, the equation is y=2x. I hope this helps! If you still have questions, ask me in the comments!
Area of a Parallelogram = base x height
base = 3.3
height = 8.4
Area = 3.3 x 8.4 = 27.72
Answer: 27.72 cm^2
Hope this helps!
