1/4 of 80 is 20 so there's 60 left the second day.
2/5 of 60 is 24.
60-24=36
There are 36 students left after the second day.
Its looks like there is no question here. Find x maybe?
the shaded part is a right triangle so we can use Pythagorean theorem
c² = a² + b²
c is the longest side of the or hypotenuse
so I can write it as m² + m² = 9²
m² + m² = 81
2m² = 81
/2 /2
m² = 40.5
√ √
m = √40.5 (well its actually = or - but since it really measurement its +)
~ 6.39
since x is to ms its 2 x 6.39
For this case we have the following expression:
We must clear the value of x in the expression.
For this, we must follow the following steps:
1) add by on both sides of the equation:
2) multiply both sides by 1 / a:
3) Common factor 1 / a:
