39 miles. If d=rt and the rate is 16 mph and the time is 3 hours then 16 times 3 gives the distance of 39 miles. I could be wrong but that is what I would have done. I’m not sure if there are answer choices or not
Answer:
11 of 20p, 22 of 10p and 33 of 5p
Step-by-step explanation:
Eva has 20p, 10p and 5p coins, total of £6.05 = 605p
Let 20p=x, 10p=y, 5p=z
<u>Then</u>:
- 20x + 10y + 5z = 605
- y : x = 2 : 1 ⇒ x= y/2
- y : z = 2 : 3 ⇒ z= 3y/2
<u>Rewriting the first equation considering next two:</u>
- 10y + 10y + 7.5y = 605
- 27.5y = 605
- y= 605/27.5
- y= 22
- x= y/2 = 22/2 = 11
- z = 3y/2 = 3*11 = 33
<u>Answer:</u> 11 of 20p coins, 22 of 10p coins and 33 of 5p coins
Because the inequality is less then or equal two the lines need to be solid, not dotted.
Also the less than would put the solution to the outside of the lines.
The correct graph is Stan.
Answer: the incorrect graph is Lee because he used dotted lines and has the solution on the wrong side of the lines
