Step-by-step explanation:
Please find the attachment.
Let x be the number of hours the student swims per day.
We have been that a student swims one hour every day, so in 2 months the student will swim 60 hours.
We are also told that the student swims 800 meters each day. This means that slope of the graph that represents the total meters swam during the time of her training program will be 800.
So in 60 days the student will swim .
We can see from our attached graph that at x equals 60 our y is approximately 48.
Since y-axis represents the number of meters in thousands, so 48 stands for 48,000.
Therefore, attached graph is the right choice.
Answer:
21 boys are there in the class.
Step-by-step explanation:
7x + 5x = 36
12x = 36
x = 36 / 12
x = 3
∴ The number of boys in the class is:
7 * 3 = 21

Answer:
1. 80 yd
2. 10 and 10 of the other side
3. yes
Step-by-step explanation:
1. As we were asked to stay 240 feet away, and we will be on a soccer field and it has marked distances in yards we just have to pass our feet to yards.
1 ft = 1/3 yd
240 ft = 240/3 yd
240 ft = 80 yd
2. one would have to stand in yard 10 and the other in yard 10 but from the other side of the field
50-10 = 40
40 + 40 = 80 yd
3.
if they are diagonally the distance will be greater than 80, since the yards are parallel, because only the distance would remain only if they are on the same height
Sum means + difference is division
<span> x + y = 92 </span>
<span> x - y = 20
</span>
2x = 92 +20
<span>2x = 112 </span>
<span>x = 56 </span>
<span>x + y =92 </span>
<span>56 + y = 92 </span>
<span>y = 36
</span><span>'
answer 36 and 56</span>
