Answer:
x=34/5 y=6/5
Step-by-step explanation:
so first you need to isolate one variable in one equation
so lets use 3x-12y=6
3x=12y+6
x=4y+2
then, as the name implies, we substitute it into the second equation
3(4y+2)-7y=12
then we simplify
12y+6-7y=12
5y=6
y=6/5
then we plug it in to find x
3x-7(6/5)=12
3x-42/5=12
3x=102/5
x=34/5
check work
3(34/5)-12(6/5)=6
102/5-72/5=6
30/5=6
6=6
Answer: y= 7 & y=5
Step-by-step explanation:
y^2-12 get half of -12 which is -6 then sq it -6 X -6 = 36 add to both sides
y^2 -12+36= -35+36
(y-6)^2= 1
Sq rt both sides
y-6=1
Add 6 to both sides
Y= 7
Y-6=-1
Add 6
Y=5
Answer:
B) 20°
Step-by-step explanation:
The top half of the circle is equal to 180°...
13x + 3x + 2x = 180°
18x = 180°
x = 10°
Angle EOD is the opposite angle of 2x
2 (10) = 20°
