Answer:
tip: 15.25; each person paid $22.88 (that is rounded up from 22.875)
we have
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Divide both sides by
Rewrite as perfect squares
Taking the square roots of both sides (square root property of equality)
Remember that
<u>the answer is</u>
The solutions are
Answer:
<em>The equation which has no solution is 5 + 2(3 + 2x) = x + 3(x + 1) . </em>(see below for work)
Step-by-step explanation:
4(x + 3) + 2x = 6(x + 2)
4x + 12 + 2x = 6(x + 12)
4x + 2x = 6x
6x = 6x
x ∈ ℝ
5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 4x = x + 3(x + 3)
11 + 4x = x + 3x + 3
11 + 4x = 4x + 3
11 = 3
x ∈ ∅ (CORRECT ANSWER)
5(x + 3) + x = 4(x + 3) + 3
5x + 15 + x = 4x + 12 + 3
6x + 15 = 4x + 12 + 3
6x + 15 = 4x + 15
6x = 4x
6x - 4x = 0
2x = 0
x = 0
4 + 6(2 + x) = 2(3x + 8)
4 + 12 + 6x = 6x + 16
4 ÷ 12 = 16
16 = 16
x ∈ ℝ
Hope this helps! :)
