Answer:
Step-by-step explanation:
Multiply the first bracket by 13
Multiply the second bracket by -4
13(6-x)-4(3x+12)=0
78-13x-12x-48=0
30-25x=0
-25x+30-30=0-30
-25x=-30
Divide by -25 for -25x and-30
x=30/25 reducing: 6/5= 1 1/5
Answer can be 30/25 or 6/5 or 1 1/5
Answer:
x=10, y=4
Step-by-step explanation:
3x-3y=18
(-)3x-(-)8y=-(-)2 -3x+8y=2 add to first equation to eliminate x
5y=20
y=4
substitute y with 4
3x-3(4)=18
3x=30
x=10
x=10,y=4
Answer:
48 ft^2
Step-by-step explanation:
5.5 times 6 equals 33 (larger square part)
2.5 times 6 equals 15 (two triangles combined so you dont have to 1/2)
