Answer:
B. Minor arc
Step-by-step explanation:
The central angle that is subtended by arc XY is less than 180° and it is not up to a semicircle.
A semicircle is half of a circle of which its central angle measure exactly 180°
The central angle of which an arc is subtended measures more than 180°.
Therefore, arc XY, which has a central angle that subtends it measuring 155° can be said to be a minor arc.
A dozen is equal to 12 so you have to do 12 x 9 = 108.
108 ÷ 4 = 27 so there was 27 rolls in each box.
Answer:
There is one solution
Step-by-step explanation:
2x + y = -1
8x + 3y = -2
Multiply the first equation by -4
-8x -4y = 4
Then add the equations together to eliminate x
-8x -4y = 4
8x + 3y = -2
--------------------
-y = 2
Multiply by -1
y =-2
Now find x
2x+y =-1
2x+-2 =-1
Add 2 to each side
2x-2+2=-1+2
2x=1
Divide by 2
x = 1/2
Answer:
19
Step-by-step explanation:
X will refer to the number.
X+57( the number added to the original.)=4x. (x time 4)
X+57=4x.
Subtract x from both sides to get the variable on one side.
(X+57)-x =(4x)-x
57=3x. You would then divide by 3 on both sides to again get integer isolated.
57/3=3/3x.
57/3=19. 3/3=1.
19=x.
