Because you are solving to find the total amount and you were given that the tax is 8% you’d do $999 times 0.08 and you’d get $79.92 and then you’d add $79.92 to $999 to find the total amount charge to his card and you’d get $1078.92

Solve each system by graphing. If the solution is not unique, identify the system as “inconsistent” or “dependent”

lapo4ka [179]

Answer:

therefore the solution of the system of equations is (x,y) = (4,2)

the solution is unique and therefore the the system is neither "inconsistent" nor "dependent"

Step-by-step explanation:

i) x + 2 = 6 $\Rightarrow$ x = 4

ii) x - y = 2 $\Rightarrow$ 4 - y = 2 , therefore y = 4 - 2 , therefore y = 2

iii) therefore the solution of the system of equations is (x,y) = (4,2)

iv) the solution is unique and therefore the the system is neither "inconsistent" nor "dependent"

erik drove 439.92 miles on 15.6 gallons of gas. To the nearest hundredth, how many miles could he drive on 39.7 gallons of gas?

zaharov [31]

First you divide 439.92 by 15.6 and you get 28.2 which is how many miles per gallon that you are getting. Then you take 28.2 and multiply it by how many gallons that it says (39.7) The final answer is 1119.54
