Answer:
A
Step-by-step explanation:
Given
x - 9 > 3 ( add 9 to both sides )
x > 12
13, 15 and 17 are all greater than 12
However, 11 is less than 12 and is not in the solution set → A
Answer:
We know that the kite with the tail is 15 feet and 6 inches. While 6 inches is 0,50 foot, it's 15,5 feet. If the lenght of the kite is x, then:
15,5 = x + 1,5 + 2x
15,5 = 3x + 1,5 / - 1,5 (both sides)
14 = 3x / : 3 (both sides)
x ≈ 4,66
The kite is approx .4,66 feet long. It means that the tail is about 15,5 - 4,66 = 10,84 feet long.
There is a formula for the area of a parallelogram which is bxh
(base x height)
Remember the height is always straight so do not use the 12 value.
21x9=189
Hope this helped!
Answer:
3y(4y-1)-2y(6y-5)=9y-8(3+y)
12y∧2-3y-12y∧2+10y=9y-24-8y
12y∧2-12y∧2-3y+10y=9y-8y-24
7y=y-24
7y-y=-24
6y=-24
y=-24/6=-4
