Kenji visits Death Valley, California, which is 282 feet below sea level. He goes home later that day. If his house sits 311 feet above sea level, what is the difference in elevation between his house and Death Valley?

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

they are simplified

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
