Answer:
equation 1: x-5=-8 <=> x=-3
equation 2: x-3=-6 <=> x=-3
equation 3: x.3=-9 <=> x=-3
equation 4: -9 : x=3 <=> x=-3
=> Four equations that have –3 as the solution: x=-3
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Note ∠ Q is a right angle = 90°
Sum the angles and equate to 180
7b + 14 + 6b + 11 + 90 = 180, that is
13b + 115 = 180 ( subtract 115 from both sides )
13b = 65 ( divide both sides by 13 )
b = 5
Thus
∠ R = 6b + 11 = 6(5) + 11 = 30 + 11 = 41°
∠ S = 7b + 14 = 7(5) + 14 = 35 + 14 = 49°
∠ Q = 90°
Answer:
495 in
Step-by-step explanation:
The formula for the volume of a triangular prism is V =
· w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.
V =
· 5 · 11 · 18
V = 2.5 · 11 · 18
V = 27.5 · 18
V = 495
