I would need more information from the question to give an answer for each trapezoid.
Answer:
z = -5
Step-by-step explanation:
3(0.7z + 2.8) = 7(1.5z + 7.2)
2.1z + 8.4 = 10.5z + 50.4
2.1z - 10.5z = 50.4 - 8.4
-8.4z = 42
z = 42/(-8.4)
z = -5
The standard form: Ax + By = C
y = 90 - 15x <em>add 15x to both sides</em>
<h3>15x + y = 90</h3>
Answer:
37.68
Step-by-step explanation:
use the formula pi(3.14)r^2 h/3
Since there are 5 possible outcomes and 3 is only one of the outcomes, the probability would be 1/5 or 20%
