Answer: 99
Step-by-step explanation:
10x-9=9x
-9=-x
x=9
angle 7 = 9*(9)=81
angle 6 = 180-81= 99
NOTE: DO NOT hit 90 because I did that and got it wrong. Just a heads up. Get luck!

Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
Answer:
30x+12
Step-by-step explanation:
distribute 6 into (2x+1) and 3 into (6x+2) basically multiply
12x+6+18x+6
combine like terms
12x+18x=30x
6+6=18
hope this helps
