Answer:

16

Step-by-step explanation:

First, we solve for x.

2x+7=-21\\2x=-28\\x=-14

We now evaluate 2-x, plugging in -14 for x.

2-x\\2-(-14)\\2+14\\16

Order from least to greatest ! 1.36,1.3,1.63 and this other 0.42,3.74,3.47.
frosja888 [35]
If you are putting them all in order from least to greatest it would be 0.42, 1.3, 1.36, 1.63, 3.47,3.74. But, if you are separating them the first set of three numbers you wrote would be ordered 1.3, 1.36, 1.63. Then, the second set would be ordered 0.42, 3.47, 3.74. Hope this helped!!!
