Answer:
B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
Answer:
It can be anything if you put in the right number
Step-by-step explanation:
Answer:
Smallest angle = 23
Middle angle = 23 + 44 = 67
Right angle = 90
Step-by-step explanation:
Givens
Let the smallest angle = x
Let the middle angle = x + 44
Let the right angle = 90 which it always does.
All triangles = 180 degrees.
Equation
x + x + 44 + 90 = 180
Solution
2x + 44 + 90 = 180 Combine the left
2x + 134 = 180 Subtract 134 from both sides
2x +134-134 = 180 - 134 Combine
2x = 46 Divide by 2
2x/2 = 46/2 Do the division
x = 23

20x = 21x-3
-x= -3
x= 3
20(3)= 60°
21(3)-3= 63-3= 60°
the answer to the question is b
