4+4+2+2=12
Answer:4000
Step-by-step explanation:40 times 100 is 4000
Use substitution.
y = 2 - x and y = 4x + 7 can become
2 - x = 4x + 7
Now solve for x
-5 = 5x
-1 = x
Now plug -1 for x in either equation.
y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3
So C) is the correct answer.
0.09/10=0.009
we check it: 0.009*10=0.09, so it's right
