Answer:
x = 1
Step-by-step explanation:
<em>the important thing to know here is that if you do something to both sides of an equation (eg, add 2) the equation will still be equal. </em>
- 9x - 17 = - 26
add 17 to both sides of the equation
-9x - 17 + 17 = -26 + 17
-9x = -9
divide both sides of the equation by -9
-9x/-9 = -9/-9
x = 1
Subtract x from each side, divide each side by 3
Answer: y = - (1/3) - 1
Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
Answer:
n=6.25
Step-by-step explanation:
