Second question is 12
Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
Answer:
x=12
Step-by-step explanation:
height of tree)/(shadow length of tree) = (height of pole)/(shadow length of pole)
x/26 = 6/13
13x = 26*6
13x = 156
x = 156/13
x = 12
