Since they both have 3x terms subtract the second from the first to get rid of the x terms...
3x+2y=10
-3x+y=-13
__________
3y=-3
y=-1, which makes 3x+2y=10 become: 3x-2=10 so
x=4
So the solution is the point (4, -1)
I don't know if this is 100% correct but.. 9(x)-4(x)
Difference means subtract
So speed = distance divided by time, therefore 70 miles divided by 35 minutes = 120mph. The speedboats speed was 120mph.
Hope this helps
Answer:
Step-by-step explanation:
Difference in the distance = 50 yards
Difference in speed = 8 - 6 = 2 y/s
<u>Time to cover the gap is:</u>
<u>Sandra will run the distance:</u>
Move variable to the left. -w= -10+ 4W
-w-4W =-10
Collect like terms
-5w=-10 divide both sides by 5
