Answer:
10 girls and 11 boys
Step-by-step explanation:
That is the answer!!
If you already have any two sides of a right angle then the Pythagoras theorem would help.
It goes like (Hypotenuse)² = (Side A)² + (Side B)².
If you want to know more then just text me.
Hope this helps.
Answer:
x = 5
y = 4
Step-by-step explanation:
1. 2x + 2y = 18
2. x + 3y = 17
Multiply the first equation by 1 and the second equation by 2 to eliminate x
We have
2x + 2y = 18
2x + 6y = 34
Subtract equation 2 from equation 1
-4y = -16
Divide both sides by -4 to isolate y
-4y/-4 = -16/-4
y = 4
Now substitute 4 for y in either equation to get x. Using equation 2 we have
x + 3y = 17
x + 3 x 4 = 17
x + 12 = 17
Subtract 12 from both sides
x + 12 - 12 = 17 - 12
x = 5
x = 5 and
y = 4
Ok the first I got was (1) but, the square meter I got was 0.00064516
What you do is add up the coins in two piles
1. all the coins added up
2.coins that are more than 10 cents (or equal)
take number 2 and put that in the numerator (top spot on a fraction)
and take number 1 and put it on the denominator (bottom spot on a fraction)
then simplify it if needed.
50/224 is the raw data simplify it for the real answer
25/112 is the simplest you can do so there's your answer. hope this helped :)
