Katelyn bought a hot dog for $4. she also bought some water bottles for $2 each. katelyn did not spend more than $15 on the hot dog and the water bottles. which inequality can be used to find, w, the number of water bottle katelyn could have bought?

4+2w ≤ 15

Step-by-step explanation:

Purchases:

1 hot dog for $4

w water bottles at $2 each

4 +2w

She did not spend more than 15

4+2w ≤15

Solving for w

4+2w≤15

Subtract 4 from each side

4-4+2w ≤15-4

2w≤11

Divide by 2

2w/2 ≤ 11/2

w ≤ 5.5

She could buy up to 5 water bottles

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°.
