Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar, we can use ratios to solve
20 24
--------- = ---------
5 x
Using cross products
20x = 24*5
20x = 120
Divide each side by 20
20x/20 = 120/2
x = 6
The positive number but a negative result would be :
C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish.
The positive value is she swam 10 feet up to the surface, but she is still below the surface, which would be a negative result.
The total number of books is the sum of the chapter books and picture books, 11+7 =18
Thus 18 is the total number of books
If she gave away 1/3 of the books, 6 books were given away as 1/3 of 18 is 6
=> Ella gave 6 books to her cousin
It doesn't matter because, in the end, the differences are squared and multiplying a negative by a negative yields a positive.
