Answer:
Option B
Option C
Option D
All of these are correct
Step-by-step explanation:
Option B is correct because:
2x + 1 + 2x + 3 = 4x + 4
=> 4x + 4 = 4x + 4
Option C is correct because:
x + 3x + 4 = 4x + 4
=> 4x + 4 = 4x + 4
Option D is correct because:
2(2x + 2) = 4x + 4
=> 4x + 4 = 4x + 4
Option A is incorrect because:
4(x + 4) = 4x + 4
=> 4x + 16 ≠ 4x + 4
Cross multiplication!
=
7 × 24 = 8x
168 = 8x
Divide both sides by 8 to isolate x
=
8 and 8 cancels out
21 = x
The factors are the following : 1, 2, 4, 7, 14, 28.
X = hamburgers and y = hot dogs
