Answer:
10 + m ≥ 30
You must spend AT MOST $20 or more
Step-by-step explanation:
Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be ≥ or the inequality will not be true.
10 + m ≥ 30
10 - 10 + m ≥ 30 - 10 ( subtract 10 from each side to isolate m)
m ≥ 20 ( we are left with this )
The answer is :
m ≥ 20
You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D
(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)
The negative sign separating the expressions is just multiplying the rightmost expression by -1.
(2x^2 + 4x + 6) + (3x + 5x^2 - 4)
Now, let's add together terms that share the same variable.
2x^2 + 5x^2 = 7x^2
4x + 3x = 7x
6 + (-4) = 2
Let's combine each of these terms into one expression.
7x^2 + 7x + 2 is the final answer.

Answer:
100(π+3) ≈ 614 square units
Step-by-step explanation:
Assuming the rectangles are squares, the total area is that of 3 squares and a circle of radius 10.
circle area = πr² = π·10² = 100π
area of squares = 3×s² = 3·10² = 300
Then the total area is ...
300 +100π ≈ 614 . . . square units
4. * 10^-9
4. * 10^10
6. * 10^7
4. * 10^-8
All rounded to the nearest whole number. Take the number given and move the decimal point to make the number less that 10 but greater than 1. The, count how many spaces you moved the decimal point, this will be the power of 10. If you moved the decimal point to the left, the power of 10 will be positive. If you moved it to the right, the power of 10 will be negative. Hope this helped!
