Answer:

x = -1.5.

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x - 3x + 9x = 15 - 9 - 21 - 3

12x = -18

x = -18/12

x = -1.5.

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5+ x) - 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x + 24 = 6 - 6x

12x = -18

x = -1.5

0.5x -2 = 1.5x + 0.15
frutty [35]

Answer: x=−2.15

Step-by-step explanation : Alright Let's solve your equation step-by-step.

0.5x−2=1.5x+0.15

Step 1: Subtract 1.5x from both sides.

0.5x−2−1.5x=1.5x+0.15−1.5x

−x−2=0.15

Step 2: Add 2 to both sides.

−x−2+2=0.15+2

−x=2.15

Step 3: Divide both sides by -1.

−x

−1

=

2.15

−1

x=−2.15<em>        hope this helped!- Alex</em><u> </u>

Suppose 11 people arrive at a bank at the same time. In how many ways can they line up to wait for the next available teller?
tresset_1 [31]
The answer would be C) because there are 11 possibilities of who can line up first, and after the first person, 10 possibilities, then 9, and so on. So you would need to multiply 11x10x9x8x...x1.
