Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
Sorry I’m just commenting to do it
Answer:
x = 1 or x = -1
Step-by-step explanation:
Given equation:
Factor out -1:
Divide both sides by -1:
Rearrange the terms:
Factor the first two terms and the last two terms separately:
Factor out the common term :
<u>Zero Product Property</u>: If a ⋅ b = 0 then either a = 0 or b = 0 (or both).
Using the <u>Zero Product Property</u>, set each factor equal to zero and solve for x (if possible):
Therefore, the solutions to the given equation are: x = 1 or x = -1
