Distribute the -1/2 to both x and 12
-1/2(x) = -1/2x
-1/2(12) = -6
12 - (-1/2x) - 6
Simplify: Note, two negatives = one positive
12 + 1/2x - 6
Simplify: combine common numbers together
12 - 6 + 1/2x
6 + 1/2x
1/2x + 6 is your equivalent expression
hope this helps
Answer: Your Answer to the equation is in the picture below.
Step-by-step explanation:
Answer:
Dorsey = 4.8 hours
Campbell = 24 hours
Step-by-step explanation:
It takes "x" hours for Dorsey
So, it will take 5 times more for Campbell, so
It takes "5x" hours for Campbell
Rate is inverse of time, so rates are:
Dorsey: 1/x
Campbell: 1/5x
We know Rate * Time = Work
When together, it takes 4 hours to finish a work, so we can write:
Solving for x, we get the time of Dorsey:
Dorsey takes 4.8 hours alone
Campbell takes 4.8 * 5 = 24 hours alone
Answer: 7
Step-by-step explanation:
f(x) = y
f(-5) = y
x = -5
find the value of y at x = -5
and the answer is 7
Answer:
100
Step-by-step explanation:
Okay so I'm not 100% sure but I think it's 100 because:
Angle B and D are the same, so the 12.5 areas will be the same (I honestly suck at explaining I'm really sorry.) But, if you add the sides from angle B and D it will be 50 because 12.5 + 12.5 + 12.5 + 12.5 (or 12.5 * 4). Meanwhile, For angle A and C, both outsides are the same as the other side.
I'm so sorry I can't explain the problem well but once you add them:
11.5 + 11.5 + 12.5 + 12.5 + 12.5 + 12.5 + 13.5 + 13.5 = 100
