Answer:
x,y = 13/3, -10/3
Step-by-step explanation:
8x+8y=8
8x+2y=28 Subtract eq1 by eq 2
6y=-20
y=-20/6 y = -10/3
8x - 80/3=8
8x=34 2/3
x=4 1/3
x=13/3
Hope this helps plz hit the crown :D
Answer:
x = 30
F = 130
G = 50
Step-by-step explanation:
f and g are supplementary which means they add to 180
5x-20 + 3x - 40 = 180
Combine like terms
8x - 60 = 180
Add 60 to each side
8x-60+60 = 180+60
8x = 240
Divide by 8
8x/8 = 240/8
x = 30
F = 5x -20 = 5*30 -20 = 150 -20 = 130
G = 3x-40 = 3*30 -40 = 90-40 = 50
Answer:
127.3 ft
Step-by-step explanation:
Make it a right triangle...
ΔABC is 90 by 90 by x
x = 
x = 
x = 
x = 127.3 ft
The answer is 1,342 cm squared. This problem is fairly simple, but ok.
Kilo means 1000 so 1 kiometer=1000 meter
so every 1000 meter=1 kilometer
to convert,, just divide meters by 1000 and get km
2950/1000=2.95km
