x -----> Stacy

x + 23 -----> Ryan

x + 6  Stacy

x + 23 + 6   Ryan

x + 29 Ryan

 

x + 29 = 2(x + 6)

x + 29 = 2x + 12

x - 2x = 12  - 29

-x = - 17

x = 17 Stacy

x + 23

17 + 23

If sin 115° ≈ 0.91 and cos 115° = -0.42, then sin -115° =
EastWind [94]

Answer:

sin -115° = -0.91

Step-by-step explanation:

Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).

As for point B which was revolved around -115°,

the coordinates will be similar to point A but you just have to change the negative.

B(cos -115°, sin -115°) = B(0.42, -0.91)

Viefleur [7K]
Start by dividing both sides by 2:
5x + 6 = 5x + 6
Simplify:
0 = 0
This indicates infinite solutions:
x = All real numbers.

A clown bought 5 bags of round balloons with 24 balloons in each bag. The clown also bought 3 bags of long balloons with 36 ball
dimaraw [331]

Answer:

247 blown up balloon left

Step-by-step explanation:

5 bags of round balloon with 24 balloon in each bag =

                                  = 5 x 24 = 120 round balloons

3 bags of long balloon with 36 balloon in each bag =

                                   = 3 x 36 = 108 long balloons

Part 1 Answer

120 round balloons -  108 long balloon = 12 balloons

therefore the clown bought 12 more round balloon than long balloon

 

Part 2

3 bags of heart-shaped balloons with 14 balloons in each bag =

                                    = 3 x 14= 42 heart-shaped balloons

All the balloons were blown which equals

120 round balloons + 108 long balloons + 42 heart-shaped balloons =

                                      = 270 balloons

23 balloons out of the 270 balloons burst which equals

 270 blown balloon - 23 burst balloon = 247 blown-up balloons left

so,

247 blown-up balloons were left
