Independent variable = $20
dependent variable = $0.05 cents per min
y = total month cost
x = month minutes used
y = 20 + 0.05x
Distributive property from what I recall,
we switched side of -6 and added it to 2
2x + 10 = 64 now we squared both sides to get rid of square root
2x = 54 we switched side of +10 and subtracted it from 64
x = 27 we divided both sides with 2
answer is x = 27
Answer:
Mistake was at Step 5
Step-by-step explanation:
Going from Step 4 to Step 5 you're supposed to:
Division first: 2 + (10 / 2)
Then Addition: 2 + 5
Solution = 7
Step 5 did addition first then division when it is supposed to do division first, then addition
