Answer:
9 and 3/5
Step-by-step explanation:
Nine and Three Fifths
Put -4 in place of x
-4 to the second power is 16 so it would be 16-(-12)= 28
Answer:
2=x
Step-by-step explanation:
8(4-x)=7x+2
Distribute
32 - 8x = 7x+2
Add 8x to each side
32 - 8x+8x = 7x+8x+2
32 = 15x+2
Subtract 2 from each side
32-2 = 15x+2-2
30 = 15x
Divide each side by 15
30/15 = 15x/15
2 =x
Answer:
you would need just 4 equation
I think it would have to be 5 and 6 because those two make up 11 when you add them. hope this helps
