Speed=distance/time

Speed=40miles per hour, distance=60miles

40=60/t

Cross multiply

40t=60

Divide both sides by 40

40t/40=60/40

Anuta_ua [19.1K]

Jacinda: d = 10 * t ( a rate: 10 miles per hour )
Raj : d = 1.5 + 4.5 * t
Jacinda will catch up with Raj when:
10 t = 1.5 + 4.5 t
10 t - 4.5 t = 1.5
5.5 t = 1.5
t = 1.5 : 5.5 = 0.27 hours = 16.2 min = 16 min 12 seconds

Noah has a total of 47 video games he only buys action games in sports games he has 21 warehousing in the sports games how many

kicyunya [14]

Question is not proper;Proper question is given below;

Noah has a total of 47 video games. he only buys action games and sports games. He has 21 more action games than sports games. how many action games, a, and sports games, s, does he own?

Answer:

Noah has 34 action games and 13 sports games.

Step-by-step explanation:

Given:

Total number of games he has = 47

Let the number of action games be 'a'.

Let the number of sports game be 's'.

So we can say that;

Total number of games he has is equal to sum of the number of action games and the number of sports games.

framing in equation form we get;

$a+s = 47 \ \ \ \ \ eqaution \ 1$

Also Given:

He has 21 more action games than sports games.

so we can say that;

$a=s+21 \ \ \ equation\ 2$

Now Substituting equation 2 in equation 1 we get;

$a+s=47\\\\s+21+s=47\\\\2s+21=47$

Subtracting both side by 21 we get;

$2s+21-21=47-21\\\\2s = 26$

Dividing both side by 2 we get;

$\frac{2s}{2}=\frac{26}{2}\\\\s=13$

Now Substituting the value of 's' in equation 2 we get;

$a=s+21=13+21=34$

Hence Noah has 34 action games and 13 sports games.

A northern elephant seal made 60 dives in 12 hours at this rate how many dives did the sea turtle make in seven hours

Galina-37 [17]

The answer is 56! I used a double number line! You have to get the unit rate first! Unit means 1, you have to get from 12 to 1! I did 12 divided by 12, and got 1! Whatever I do to the bottom I do to the top. So I divided 60 by 12 and got 5. Now we have to get to seven, so I multiplied 1 x 7 and got 7. Than I multiplied 5 times 7 and got 56! I hope I helped! :D
