The second option is the answer
Answer:
Part A, one solution
Part B, x=3
Step-by-step explanation:
divide both sides of the equation by 7 (5x-13=2)
move the constant to the right hand side and change its sign (5x=2+13)
add numbers (5x=15)
divide both sides of the equation by 5 (x=3)
hope this helps, have a good day
Answer: 18
Step-by-step explanation:
this is because complementary angles add up to 90 degrees so you would just subtract 72 from 90 to get your answer :)
The answer would be -2, and -2x is raised to the power of 2, making it the leading coefficient.<span />
There are a total of 10 socks
From those ten socks there are 4 white and 4 black. A total of 8 white and black socks
We are looking for the probability of selecting a white or black sock out of total socks
So the numbe of white and black socks are 8, and the total is 10
So there is a 8/10 chance to select a white or black sock (This would simplify to 4/5)
So your answer is D
