Answer:
the second answer seems to be the most reassonable
Step-by-step explanation:
18 - (8 - 3 • (2t + 5)) = 0
6t + 25 = 0
3.1 Solve : 6t+25 = 0
Subtract 25 from both sides of the equation :
6t = -25
Divide both sides of the equation by 6:
t = -25/6 = -4.167
Final answer is
t = -25/6 = -4.167
Answer:
The slope:
Step-by-step explanation:
-To determine the slope of the following points shown, you need this formula:
(
represents the slope, 
represents the first coordinate and 
represents the second coordinate)
-Apply the following points to the formula:
Then, solve:
So, the slope is 
.
Answer:y=4x+2
Step-by-step explanation:
-4x+y=2
−4x+y+4x=2+4x
y=4x+2
y=4x+2
The missing interior angle, x, of the convex polygon is 168⁰.
<h3>
Sum of interior angles of convex polygon</h3>
The sum of interior angles of a convex polygon is calculated as follows;
S = (n - 2) 180
S = (8 - 2) 180
S = (6) 180
S = 1080
The missing interior angle, x, is calculated as follows;
x + 126 + 146 + 130 + 140 + 146 + 134 + 90 = 1080
x + 912 = 1080
x = 1080 - 912
x = 168⁰
