This is the first step to do in order to be able to properly add the fractions.
Answer:
Where's the figure,my friend?
Let's test each alternative :
2 x - 9 y = 38 ( 7,5 ) :
( 2 * 7 ) - ( 9 * 5 ) = 38
14 - 45 = 38
-31 ≠ 38 ( wrong )
( 4 , - 1 ) :
( 2 * 4 ) - ( 9 * ( - 1 ) = 38
8 + 9 = 38
17 ≠ 38 ( wrong )
( 3 , - 3 ) :
2 * ( 3 ) - ( 9 * ( - 3 ) = 38
6 + 27 = 38
33 ≠ 38 ( wrong )
( 1 , - 4 ) :
2* ( 1 ) - 9 * ( - 4 ) = 38
2 + 36 = 38
38 = 38 ( Correct alternative )
( 1 , - 4 ) is correct alternative
Answer:
The formula for the area of a parallelogram is base x height.
base x height = area
So, I will form an equation. b (base) x 3 ft (height) = 18 1/3
Next divide 3 from 18 1/3, so 18 1/3 divided by 3. This equals1 6 1/9
To check: 6 1/9 x 3 = 18.3333333333 or 18 1/3
