Answer:
16x + 19
Step-by-step explanation:
Let's say number = x
two times a number = 2x or 2*x
added to -3 = 2x - 3
subtracted from twice the sum of nine times the number and 8
2(9x + 8) - (2x - 3)
Combining like terms
18x + 16 - 2x + 3
16x + 19
The primes factors of 75 are 3 and 5
Answer:
D.
Step-by-step explanation:
'Complement' = difference between an angle an 90 degrees.
'Supplement' = difference between an angle and 180 degrees.
Complement of A = 90 - A
Supplement of A = 180 - A
The problem says that the complement is 1/6 of the supplement, right ?
So <u> 90 - A = (1/6) x (180 - A)</u>
Multiply each side of this equation by 6 :
540 - 6 A = 180 - A
Subtract 180 from each side:
360 - 6 A = - A
Add 6A to each side :
360 = 5 A
Divide each side by 5 :
<u>A = 72°</u>
