A= 2 to the power of -1
Because if it's the same base no in multiplication we add the indices and in division we subtract the indicies
Answer:
The correct option is A
A) 25 degrees
Step-by-step explanation:
As two parallel line l and m are cut by the line t, the angles formed (x-10)° and < 3 are alternate angles, therefore they are equal to each other.
< 3 = (x-10)° ⇒ Equation (i)
We know that any straight line has a sum of angles equal to 180°.
Consider line t, it is divided into 3 angles due to cutting. Those angles are 85°, (2x)° and (x-10)°. The sum of these angles is 180° as stated before.
85° + (2x)° + (x-10)° = 180°
Find the value of x:
85 +2x + x - 10 = 180
3x + 75 = 180
3x = 105
x = 35°
Substitute it in Equation (i) to get the value of <3
< 3 = (35 - x)°
< 3 = (35 - 10)°
< 3 = 25°
Answer:
The number of stitches is One-fifth times the length.
Step-by-step explanation:
Answer:
Step-by-step explanation:
3x - 5y = -35
2x - 5y = -30
3x - 5y = -35
-2x + 5y = 30
x = -5
3(-5) -5y = -35
-15 - 5y = -35
-5y = -20
y = 4
