Answer:
x = 9
y = 12
Step-by-step explanation:
✔️m<ADB = 90°
7x + 27 = 90
7x = 90 - 27
7x = 63
Divide both sides by 7
x = 9
✔️BC = 2(BD)
3y - 7 = 2(y + 3)
3y - 7 = 2y + 6
Collect like terms
3y - 2y = 7 + 6
y = 12
Answer:
There are 4 common factors of 30 and 72, that are 1, 2, 3, and 6. Therefore, the greatest common factor of 30 and 72 is 6.
Step-by-step explanation:
84/18=14/3
60/32=15/8
x=-6+2y
x=2+2y
by subtraction
___________________________
x=-8
Substitute x by one of the two equations :
x=-6+2y
-8=-6+2y
2y=-8+6
2y=-2
y=-2/2
y=-1
I think this is the answer
