This is the concept of geometry, given that the angle 52 and (2x) have been subtended by a circle, then:
2x=2(52)
2x=104
solving for x we get:
x=104/2
x=52
the answer is x=52°
Answer:
12 x -7 = -84 12 + (-7) = 5

Answer:
![\frac{40}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B4%7D%20)
Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:
![\frac{40 tiles}{4} = 10 groups](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%20tiles%7D%7B4%7D%20%3D%2010%20groups%20)
Therefore, the expression modeled by the arrangement of the tiles is ![\frac{40}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B4%7D%20)
Step-by-step explanation:
-10-2x = 3x+15
5x = -25
x= -5
