X - bat
y - ball
x+y=1.1
x=y+1
(y+1)+y=1.1
y=.05
Plug the Y value back into the original equation to find X
x+.05=1.1
x=1.05
Bat cost: 1.05
Ball cost: .05
Here's a photo of the solution. Hope this helps and please give brainlist!
1 ) Reflex AOB = 290°
2 ) x = 30°
2x = 2 × 30° = 60° and 3x = 3 × 30° = 90°
3 ) k = 48°

Answer: Because Frank is planting <em>x </em>seeds in one and <em>4x+7</em> in the other, you need to add both of those together.
x+4x+7=<u> 5x+7</u>
