Answer:
A. Olivia is correct.
Step-by-step explanation:
If the total amount of gravel stated is 689 pounds and you want to check your answer, you can subtract one of the two trucks from the total. Which would be either 689 - 231 or 689 - 458. Therefore, A is the correct answer.

Answer:
As shown in picture, this is a trapezoid.
The area of a trapezoid is calculated by:
A = (base1 + base2) x height x (1/2)
To work out A, we need to find out base1, base2, and height.
base1 = YZ = 
base2 = XW =
Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.
=> A = (3 + 7) x 4 x (1/2) = 20
Hope this helps!

Answer:
a = 11/12
Step-by-step explanation:
1/3 + a =5/4
Subtract 1/3 from each side
1/3-1/3 + a =5/4-1/3
a = 5/4 -1/3
Get a common denominator of 12
a = 15/12 - 4/12
a = 11/12
