Answer:
3 cookies
Step-by-step explanation:
she has 12 cookies and 4 friends
12 / 4 = 3 cookies for each friend
Answer:
x=0 or x=6
Step-by-step explanation:
Step 1: Divide both sides by -4.
−4(|−2x+6|)
−4
=
−24
−4
|−2x+6|=6
Step 2: Solve Absolute Value.
|−2x+6|=6
We know either−2x+6=6or−2x+6=−6
−2x+6=6(Possibility 1)
−2x+6−6=6−6(Subtract 6 from both sides)
−2x=0
−2x
−2
=
0
−2
(Divide both sides by -2)
x=0.
Answer:
34.8
Step-by-step explanation:
36-1.2 = 34.8
Subtract x^2 from both sides
x^2 + 3x - 7 = 5x + 39
Subtract 5x from both sides
x^2 - 2x - 7 = 39
Add 7 to both sides
x^2 - 2x = 46
Complete the square by adding (b/2)^2 to both sides, b = ( -2)
(-2/2) = -1, then square that (-1)^2 = 1
x^2 - 2x + 1 = 46 + 1
Simplify the expression by factoring
(x - 1)^2 = 47
Take square root on each side
x - 1 = (sqrt (47))
Solve for x
x = 1 + (sqrt (47))
Since 47 is prime, 47 cannot be broken down by the square root and this is the answer to your problem.
