Answer:
60 km/h
Step-by-step explanation:
Let us use the x to represent the speed of the car since it is the smaller value.
Then, the distance covered by the car is 4x since was going 4 kph.
The distance covered by the train is (x+5) times 7 or 7x+35.
We know that the total distance covered is 640 km.
Using this information, we can set up the equation 4x+7x+35=640.
By subtracting both sides by 35 and combining the x's, we get a new equation of 11x=605.
After this, we divide both sides by 11 and get x=55.
Lastly, we add 5 to 55 since the train is 5 km faster than the car and that x stood for the car.
Train=60 km/h
Find a common denominator which is 12
1*3=3 4*3=12 so 3 3/12
then 5*2=10 6*2=12 so 2 10/12
2 10/12+3 3/12= 5 13/12
13/12= 1 1/12 plus 5= 6 1/12
so your answer would be 6 1/12
Answer:
C) p + 3 < 20
Step-by-step explanation:
Since the max is 20, it has to be < 20
p + 3 < 20
Answer: OPTION D
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- Convert from 48 inches to foot. You know that 12 inches=1 foot. Then you have:
- Therefore, keeping on mind that 48 inches is 4 feet, and you must find the ratio that correctly compares 2 feet to 48 inches, you can write:
- Reduce the fraction, then:
- You can rewrite it as following:
Answer:
<em>550 </em><em>students are in the school.</em>
Step-by-step explanation:
The way I found my answer was by first turning<em> 74% into a decimal</em>, which is <em>0.74</em>. Then I <em>divided 407 </em>by<em> 0.74</em> and I got<em> 550</em>. Therefore, <em>550 is our answer.</em>
