First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
Answer:
the equation in letter D is a linear function.
The estimate would be 2+3 5+2 and 6+1
so 577
you can also just round and do 250 +300= 550 +20=570
Based on the information given, it should be noted that the correct option is C. 3x - 8.

From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:
= (2 × x) - 8.
= 2x - 8
Also, Ricky has x dollars. Therefore, the amount that they have together will be:
= 2x - 8 + x
= 3x - 8
