65 + (3x-10) + 2x = 180
65 +5x-10 = 180
55 + 5x =180
5x = 125
x = 125/5 = 25
x = 25
B = 3(25)-10 = 75-10 = 65
C = 2(25) = 50
Answer:
Using the slope-intercept form, the slope is −4
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
(6+4)^2=100
or
6^2=36
4^2=16
6^2+4^2=36+16=52
so it is false
11. 8 * 18 =
144 in³, Option D
12. Half the height of 8 cm is 4 cm. Volume = 4 * 6 * 10 =
240 cm³, Option D
13. Double the dimensions you get 8 cm for the height, 6 cm for the radius. Then plug in. V = pi * (6)² * 8 >> pi * 36 * 8 =
288pi or ≈ 904.78, Option C
14. Half of all the dimensions are 1 in, 4 in, and 3 in. 1 * 4 * 3 =
12 in³, Option B
15.

>> 16x = 180 >> x = 11.25
so Option B
16. Option D, 10 cm.
17. Option C, 8.5 in
18. Option B. 10.2 km
19. Option D. 0.82
20. cos 30 = b / 11.5 >> b = 11.5(cos (30)) =
9.96 m, Option C.
