Answer:
The Biden administration is extending a mask mandate for airplanes and transit for 15 days, the Centers for Disease Control and Prevention said Wednesday.
The mandate was set to expire after April 18, following a one-month extension announced in March. Airlines have required masks on planes since early in the pandemic in 2020, but the Biden administration made them mandatory in early 2021.
The CDC said it is monitoring the spread of omicron, including the BA.2 subvariant.

Answer:
Step-by-step explanation:
x + y = 7 ------------(I)
y = 7 - x ------------(II)
x + 2y = 11 --------------(III)
Substitute y = 7 - x in equation (III)
x + 2 * (7 -x) = 11
x + 2*7 - 2*x = 11
x + 14 - 2x = 11
x - 2x + 14 = 11
- x + 14 = 11
Subtract 14 from both side
-x = 11 - 14
-x = -3
Multiply both sides by (-1)
x = 3
Substitute x=3 in equation (II)
y = 7 - 3
y = 4
Rationalizing is just simpllifying, so the simplified value has the same value as the original expression.
