Answer: B. 1/2 (6x + 12) = 3x + 6
Step-by-step explanation:
= 1/2 (6x + 12)
= 1/2(6x) + 1/2(12)
= 6x/2 + 12/2
= 3x + 6
Answer: 90
Step-by-step explanation:
In the number 73,951, the digit 9 is on the third position, so you need to put the number of the position minus one zeros before it: ( position number 3, 3 - 1 = 2, so we put 2 zeros)
the 9 in that digit represents a 900.
now, 1/10 times that number is:
900*(1/10) = 900/10 = 90
then the answer is 90.
In the number 90, the value represented by the 9 is equal to 1./10 times the value represented by the 9 in 73,951

Answer:
42° and 48°
Step-by-step explanation:
Complementary angles sum to 90°, hence
x + 10 + x + 4 = 90
2x + 14 = 90 ( subtract 14 from both sides )
2x = 76 ( divide both sides by 2 )
x = 38
x + 10 = 38 + 10 = 48° and x + 4 = 38 + 4 = 42°
