If you 6,700 marbles and you want to share them equally amongst 20 friends, not using long division but what other strategies can you use to you solve this problem?

The box or area method

Step-by-step explanation:

Step-by-step explanation:

U first set the fraction : 6700/20.

U can cancel out the zeroes, to get 670/2.

Then u basically find half of 670, by doing half of 600 plus half of 70, which is 335

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
