I need help really soon please help me Lin got a $70 gift card to an online music store. She uses the gift card to buy an album for $10.99. She also wants to use the gift card to buy some songs. Each song costs $1.09.

Which of these inequalities describes this situation, where n is the number of songs Lin wants to buy?

Group of answer choices

10.99+1.09≥70

10.99+1.09≤70

10.99−1.09≥70

10.99−1.09≤70

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
