Answer:
Your answer would be x+y=531 and y=2x
Step-by-step explanation:
We know that Nancy bought 531 shirts and that some are long sleeved and some are short sleeved. Since x represents the long sleeved shirts and y represents the short sleeved shirts, x+y=531. We also know that there are twice as many short sleeved shirts as long sleeved shirts. So, y=2x.
Answer:
An advantage of using observation is it gives you more details than assuming or modeling would.
A disadvantage is how long it takes to get your answer.
The sample is the students and the population is 10.
If 3 out of 10 students use social media then 30% of the schools population probably uses social media.
Step-by-step explanation:
Divide by 2
Y = 2x - 2.5
x intercept: when y = 0
0 = 2x - 2.5
2.5 = 2x, x = 1.25
y intercept: when x = 0
Y = 2(0) - 2.5, y = -2.5
Solution: (1.25, 0) and (0, -2.5)
