Question

Austin solved an inequality and made an error.
3.5t – 2.75 ≤ 11.25
3.5t – 2.75 + 2.75 ≤ 11.25 + 2.75
3.5t ≤ 14
3.5t/3.5 ≤ 14/3.5
t ≥ 4
Which statement best describes Austin’s error?

A. Austin made an addition error.
B. Austin made a division error.
C. Austin should not have changed the inequality sign.
D. Austin should have changed the inequality sign to <.

Answer 1

The answer is C . I know you took the test thing already but didn’t know if you knew the correct answer :))

Answer 2

The correct answer is statement C.

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤. To 'solve' an inequality means to find a range, or ranges, of values that an unknown x can take and still satisfy the inequality.

How to find which statement best describes Austin’s error?

Austin solved an inequality and made an error.

3.5t – 2.75 ≤ 11.25

3.5t – 2.75 + 2.75 ≤ 11.25 + 2.75

3.5t ≤ 14

3.5t/3.5 ≤ 14/3.5

t ≥ 4

Here Austin should not have changed the inequality sign, this is wrong.
