Answer:
see explanation
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Summing the 3 angles and equating to 180 gives
2x + 3 + 4x + 2 + 2x - 1 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°
∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°
∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°
We assume you are converting between dollar bill and cent.
Answer:
20%
Step-by-step explanation:
Since sample size is greater than 30%
Sample of students = 240
Total student = 1200
Therefore we have
240/1200 * 100=2%
Answer:
6 mm
Step-by-step explanation:
In the smaller figure, the short side is 4/28 = 1/7 the length of the long side. Since the figures are similar, the same will be true in the large figure:
k = (1/7)(42 mm)
k = 6 mm
(2x - 8) - (4x + 8)
first look at the x
2x - 4x = -2x
-2x is left over
then look at the numbers
8 - (-8)
in the case of having two negatives, it becomes positive, and so it is really 8 + 8
8 + 8 = 16
-2x - 16 is your answer
hope this helps
