Answer:
I think the answer choices are incorrect. 7 1/2 in decimal form would be 7.5. Please correct me if I'm wrong.
Step-by-step explanation:
The value for x is already given; x = -2
Substitute -2 in for x in the second equation.
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
The final answer is (-2, 5/3).
Answer:
11/36
Step-by-step explanation:
To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.
