Answer:
90 miles
Step-by-step explanation:
2 hours = work
speed = x
Distance to work = y
y = 2x
y = 3(x - 15)
3 * x = 3x
3 * -15 = -45
y = 2x
y = 3x - 45
Let's graph this (attached below)
We must find the point at which they intercept.
They intercept at (45, 90)
That means that x = 45 and y = 90
So, she is 90 miles from her office.
Let's check our work:
y = 2(45)
y = 3(45) - 45
y = y
y = 90
2 * 45 = 90
3 * 45 = 135
135 - 45 = 90
This proves that y = y and that y = 90.
Answer:
A
B. No
Step-by-step explanation:
The winning swim team camned 245 points.
The other teams earned at least 72 points less, this means the other teams earned 72 points less, or 73 points less, or 74 points less, ...
The greatest number of points the other teams earned is
245 - 72 = 173 points
A. Let x be the number of points the other teams earned. So, the inequality that represents the points that the other teams earned is
B. The winning team earned 245 points (not 180 points). Each other team earned 173 points or less, so there are no teams which earned 180 points.
