The answer is A
Multiply the 2nd equation by -2
-2x -12y = -8
Then add it to the 1st equation
-9y = -6
y = 2/3
By substituting in the 1st equation
2x + 3(2/3) = 2
2x = 0
x=0
Answer: 28.59=g is incorrect.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Bill for additional data usage: $28.50
Cost per gigabyte: $9
To calculate the additional gigabytes we have to write an expression where the total bill ($28.5) is equal to the gigabytes used (g) multiplied by the cost per gigabyte.
Mathematically speaking:
28.5 = 9g
The three first options are correct (one is put in a different order but is the same expression). So, the incorrect option is (28.59=g).
