Answer: Boys = 1024

Girls = 972

Step-by-step explanation:

Let the number of boys = x ...... ( 1 )

Therefore the number of girls = x - 52 ..…... (2 ) ( x < 52 )

X + x - 52 = 1996

2x - 52 = 1996

2x = 1996 + 52

2x = 2048

X = 2048/2

X = 1024

Substitute for x in equation ...( 2 ) to get the number of girls

1024 - 52 = 972

Now , number of boys = 1024

And number of girls = 972

75 percent of 88 is the same as 60 percent of what number?
tangare [24]
First we need to know 75% of 88.
To find this number we multiply 88 by 0.75. 
Hence, 0.75 * 88 = 66

Therefore, 60% of a certain number equals 66.
Then 1% of that certain number equals 66 / 60
Finally, to find our number (which equals 100%) we multiply by 100.
So 66 / 60 * 100 = 110.

Hence, 75 percent of 88 is the same as 60 percent of 110.

What is the formula for an eastbound car is going 4 miles per hour faster than a westbound car. the cars are 208 miles apart 2 h
ivanzaharov [21]
Draw a diagram to illustrate the problem as shown below.

Let v = speed of the westbound car, mph

Because the eastbound car travels 4 mph faster than the westbound car, its speed is (v+4) mph.

After 2 hours,
the westbound car travels 2v miles west, and the eastbound car travels 2(v+4) miles east.
Because they become separated by 208 miles, therefore
2v + 2(v+4) = 208
4v + 8 = 208
4v = 200
v = 50 mph

The westbound car travels at 50 mph.
The eastbound car travels at v+4 = 54 mph

Answer: The eastbound car travels at 54 mph.
