Answer:
x=41 et y=131
Step-by-step explanation:
49+x=90
x=90-49=41
---------------------------
y=90+x
y=90+41=131
131°
take the line with angle 49°
st line angle is 180°
49+90+a = 180 where (a+90=y)
139+a = 180
a = 180-139=. 41°
by opposite angles equal axiom a =x = 41°
y = 131°
Yvette cleared 10 large driveways
small driveway = x
big driveway = y
x+y = 25
15x + 25y = 475
y = 25-x
15x + 25(25-x) = 475
-10x + 625 = 475
10x = 150
x= 15
15 + y = 25
y =10
10 large driveways, 1 5 small driveways
Equivalent expression
y/3 = 1/3 * y
Thisis your answer ☺️☺️☺️
x=2 y=11
