(3 yard/sec) x (3,600 sec/hr) x (1 mile / 1,760 yard) =
(3 x 3,600 / 1,760) (mile/hour) = 6.136... mph (rounded)
Answer:
no of course its not.
Step-by-step explanation:
(9 × 100) + (2 ×10) + (3 × 110) + (5 × 1100)
900+20+330+5500
1800
92.35 isnt equal to 1800
That would be .82 as 82% is 82/100 so that makes the answer .82
Answer:
9. x=-6, y=0
10. x=-9, y=-10
11. x=3, y=-1
Step-by-step explanation:

Multiply the first equation by 2.

Add the equations.


We figured out x now we have to figure out y. To figure out y plug in x into any equation.




Your answer is x = -6 and y = 0 for number nine.

Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.

Add them.


Now we have to figure out y.




x=-9 and y=-10 is your answer to number ten.








x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.
