Expand and simplify 3(x+2)+2(x-1)

lilavasa [31]

If you would like to expand and simplify 3 * (x + 2) + 2 * (x - 1), you can do this using the following steps:

3 * (x + 2) + 2 * (x - 1) = 3 * x + 3 * 2 + 2 * x - 2 * 1 = 5 * x + 6 - 2 = 5 * x + 4

The correct result would be 5 * x + 4.

Math word problem,<br> thank you

ivanzaharov [21]

Answer:

$81.92

Step-by-step explanation:

Week 1:

250 * 20% = 50

250 - 50 = 200

Week 2:

200 * 20% = 40

200 - 40 = 160

Week 3:

160 * 20% = 32

160 - 32 = 128

Week 4:

128 * 20% = 25.6

128 - 25.6 = 102.4

Week 5:

102.4 * 20% = 20.48

102.4 - 20.48 = 81.92
