Answer:
25.7minutes
Step-by-step explanation:
D =r×t=2×1.5=3miles
A D=7÷2=3.5
7=1h. 3.5=30minutes.
3.5=30
0.5=x
3.5x÷3.5=15÷3.5
X=4.3
(3.5-0.5)=(30-4.3)
Hence it takes Amanda 25.7minutes to catch up with Ben.
Maria does 1/40th of the driveway per minute. Tom does 1/35th. Together, they do:
1/40+1/35=75/1400=3/56
1/3/56=56/3, or 18&2/3 minutes working together

Improper because the top is supposed to be lower than the bottom
Answer:
169 meters
Step-by-step explanation:
52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)
13^2=169 (to find the area you square the length of each side)
2x – 6y = 12
for x = 1
2 - 6y = 12
y = -10/6
y = -5/3
For x = 2
4 – 6y = 12
y = -8/6
y = -4/3
For x = 3
6 – 6y = 12
<span>y = -1</span><span>
<span><span>
<span>
Hence
x =

</span>
<span>
<span>
1 then y = -5/3
</span></span><span>x = 2 then y = -4/3
</span><span>x = 3 then y = -1</span></span></span>
