Answer:
y = -11.5
Step-by-step explanation:
2y = 18-41
Combine like terms
2y = -23
Divide each side by 2
2y/2 = -23/2
y = -11.5
Answer:
Positive
Step-by-step explanation:
neg x neg = pos
neg x neg = pos
pos x pos x pos = pos
X= entire test
if
18=.9x
then divide both sides by .9
18/ .9
and x = 20

Answer: 4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
