Answer:
slope = 1/7
Step-by-step explanation:
7x+y=9 you should be in slope int form--> y=-7x+9
then the line is perpendicular so
the slope is 1/7
Answer:
1500 ft^2
Step-by-step explanation:
The area of a triangle is 
, where b = base and h = height. In this triangle, we're given the base as 120 and the height as 25. 120 × 25 is 3000, and 3000 divided by 2 is 1500 ft^2.
Therefore, the answer is 1500 ft^2.

2x+50 and 7x are "vertical angles" and are thus equal to one another.
2x+50 = 7x
50 = 5x
x=10 (answer) You should find the actual angles.
They are 2(10)+50 = 70 and
7(10) = 70
Answer:
$ 4.75
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x: price of drinks
let y: bags of popcorn price
SW:
3 * x + 5 * y = 26.75
9 * x + 2 * y = 18.50 => x = (18.5 - 2 * y) / 9
Replacing, we are left with that:
3 * (18.5 - 2 * y) / 9 + 5 * y = 26.75
6.167- 0.67 * y + 5 * y = 26.75
- 0.67 * y + 5 * y = 26.75 - 6.167
4.33 * y = 20,583
y = 20,583 / 4.33
y = 4.75
Now to calculate x:
x = (18.5 - 2 * 4.75) / 9
x = 1
That is, the value of the drinks is $ 1 and the value of bags of popcorn is $ 4.75
