Answer: $8 chicken $5 duck
Step-by-step explanation:
50x+30y=550
x=8
y=5
400+150=550
Answer:
If they're equal set them equal to each other if they're supplementary you set up an equation. Where you add them up and set them equal to 180. And then you just want to solve for X.
Answer:
so if x = 0, x = 2, and x = 4
3(0) + 2 = 0 + 2 = 2, so when x = 0, y = 2
3(2) + 2 = 6 + 2 = 8, so when x = 2, y = 8
3(4) + 2 = 12 + 2 = 14, so when x = 4, y = 14
Question 1:
For this case we must rewrite the following equation:

If we add 3x to both sides of the equation we have:

Thus, we have that an equivalent expression is option C.
Answer:
Option C

Question 2:
For this case we must solve the following equation:

Subtracting 5 from both sides of the equation we have:

Dividing between -5 on both sides of the equation we have:

Answer:
Option B
