Question

Use absolute value to write an expression describing the size of each amount. a. An elevation of 250 feet. b. A credit card balance of $23.75. c. A football player rushed for -5 yards. d. A bank balance of $198.32. e. An elevation of Death Valley of -86 m.

Answer 1

We know that, 'The absolute value is the magnitude regardless of the sign'. It is represented by the sign |x| i.e. absolute value of x.

So, we are given that,

A. An elevation of 250 feet.

Then, the absolute value = |250| = 250.

B. A credit card balance of $23.75

Thus, the absolute value = |23.75| = $23.75

C. A football player rushed for -5 yards.

The absolute value = |-5| = 5 yards

D. A bank balance of $198.32

Thus, the absolute value = |198.32| = $198.32

E. An elevation of Death Valley of -86 m

The absolute value = |-86| = 86 m
