hello
8 the no right answer to 2(4x - 6) = 6x - 4
because : 2(4(8)-6) = 6(8)-4
2(26) = 48-4
52 =44
The answer is B
A number line from negative 8 to positive 8 in increments of 1, with only whole numbers that are multiples of 2 labeled. Place point P at the third tick mark to the left of 0. Put point Q at the fifth tick mark to the right of 0.
Answer:
∠A = 70°, ∠B = 50°, and ∠C = 60°.
Step-by-step explanation:
In a triangle ΔABC, ∠A + ∠B + ∠C = 180° ......... (1), we know from the property of triangle.
Now, the sum of ∠C and the exterior angle adjacent to ∠C is 180°.
If the exterior angle adjacent to ∠C is 120°, then ∠C = 180° - 120° = 60°.
Now, from equation (1), ∠A + ∠B = 180° - ∠C = 180° - 60° = 120° ......... (2)
Now, given that ∠A = 2x and ∠B = x + 15.
Hence, from equation (2), we have, 2x + x + 15 = 120
⇒ 3x = 105
⇒ x = 35.
Therefore, ∠A = 2x = 2 × 35 = 70°
∠B = x + 15 = 35 + 15 = 50°
and ∠C = 60° (Answer)

(e) note that the terms have a common difference (d )
d = 26 - 12 = 40 - 26 = 54 - 40 = 14
to obtain any term in the sequence, add 14 to the previous term
54 + 14 = 68
68 + 14 = 82
82 + 14 = 96
The whole unit ( numbers to the left of the decimal will remain as the degrees:
270 will remain as degrees
now multiply the decimal by 60:
0.50 * 60 = 30 ( this becomes the minutes) if the answer had a decimal, you would multiply that decimal by 60 for the seconds, but since multiplying 0.50 by 60 was a whole number there are zero seconds
so the answer becomes 270 degrees 30 minutes and 0 seconds
which is written like: 270°30'0"
