Answer:
Add I, add 9, repeat.
Step-by-step explanation:
It is because if you look at the Add 9 subtract 8, repeat. it won't work
If you look at add 10, subtract 9, repeat. it its just like the first one, it won't work.
If you look at add 1, add 10, repeat, it also won't work from when you are getting 6 to 15.
So if you look at Add I, add 9, repeat., it works for all.
Answer: 56
Step-by-step explanation:
7-2x=-27
-2x=-34
x=17
so 3x+5=3(17)+5=56
Answer: 2(x+1)
Step-by-step explanation: free points right?
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
31 + x + 4 + 3x + 9 = 180, that is
4x + 44 = 180 ( subtract 44 from both sides )
4x = 136 ( divide both sides by 4 )
x = 34
Thus
∠ S = x + 4 = 34 + 4 = 38°
∠ T = 3x + 9 = 3(34) + 9 = 102 + 9 = 111°
Answer:
Step-by-step explanation:
The diagonals of a rectangle are equal.
2x + 10 = 56 That minus sign can't be there. Subtract 10 from both sides.
2x = 56 - 10 Combine
2x = 46 Divide by 2
x = 46/2
x = 23
