722.25
Step-by-step explanation:
675x1.07
1 would be 675. Since there is a 7 percent sales tax, it would be 107 percent of the cost.
So number 1 all u have to do is add all of the fractions together then what do u get? 23/24 so whats left of the money? 1/24 now number 2, i belive your suppose to add 2/3 and 3/5 then u would get 19/15 so then the answer would be 4 because the fraction for an number that is bigger on the top is always divided by the top, hope that helps a lil bit XD

Answer:
x ≈ -7.73 , - 4.27
Step-by-step explanation:
x² + 12x + 33 = 0 ( subtract 33 from both sides )
x² + 12x = - 33
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = - 33 + 36
(x + 6)² = 3 ← take square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ±
Then
x = - 6 - ≈ - 7.73 ( to the nearest hundredth )
x = - 6 + ≈ - 4.27 ( to the nearest hundredth )
Answer:
(-1, 1)
Step-by-step explanation:
I used a graphing tool to graph the equations. When graphed, they cross at coordinate (-1, 1). Therefore, (-1, 1) is the solution.
