Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which
weqwewe [10]

Answer:

10n \le 30

n \le 3

Step-by-step explanation:

Given

Total = \$30

Cost (each) = \$10

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

10n \le 30

<em>We used </em>\le<em> because the amount she wants to spend cannot exceed 30</em>

Divide both sides by 10, to solve for n

n \le 3

Help me please i will mark who ever the brainly thing .
ddd [48]

Answer:B *54 degrees*

Step-by-step explanation:

2x-10 + 1/2x + 20 = 180

add up like terms

2.5x + 10 = 180

subtract 10 from both sides

2.5x = 170

divide by 2.5 on both sides

x = 68

now plug in x to the (2x-10) expression [which will get you 126 degrees]

then subtract 180 - 126 to fine angle y. which should get you *54 degrees*

Answer:

Least to Greatest

-1.98, -0.9, -1 \frac{8}{9}, -1.68
