Answer:
Step-by-step explanation:
y = 5x + 4
-5x + y = 4 ----------------------(i)
3x + 2y = 20 --------------------(ii)
Multiply equation (i) by (-2)
(i)* (-2) 10x - 2y = -8
(ii) <u>3x + 2y = 20</u> { Now add this two equations}
13x = 12 { -2y and 2y got eliminated}
x = 12/13
Plug in value of x in (i)
-5*12/13 + y = 4
-60/13 + y = 4
y = 4 + 60/13

Answer: 108 pancakes
Step-by-step explanation:
if you make 20 pancakes with 1 and 2/3 of flour,
with 9 cups you will make
(20*9)/ 1 &2/3
1 2/3= 5/3 we enter the whole in the fraction
(180)/(5/3)= 180*3/5=108 pancakes
Answer:
Construct the angle bisector of angle Y
Step-by-step explanation:
-An inscribed circle is defined as the largest circle that can be drawn within the boundaries of a plane figure.
-The first step in constructing an inscribed circle is to bisect any two angles of the plane figure, triangle in this case, as there intersection point will form the circle's center.
=>Hence, the first step is Construct the angle bisector of angle Y or Z or X( whichever you decide on).
