Answer:
{-3, 5}.
Step-by-step explanation:
y = x + 8
x + y = 2
Substitute y = x + 8 in the second equation:
x + x + 8 = 2
2x + 8 = 2
2x = -6
x = -3
Now plug this into the first equation
y = -3 + 8 = 5.
The equation would be .35x +15.50!
You can subtract 15.50 from 16.90 to get 1.40. Then divide 1.40 by .35! You would get 4! Good luck!
If sqrt x = 9 then x = 9*9 = 81
Answer is between 80 and 90.
Answer:
12
Step-by-step explanation:
7x+10=94
-10 -10
7x=84
7x/7=84/7
x=12
4x-6=42
+6 +6
4x=48
4x/4=48/4
x=12
