First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.
-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.
So now we solved those and we got this answer: 2.11
Now, we need to subtract and re-write the expression.
2.11 - (-7.423) = 2.11 + 7.423= 9.533
Ok....so now we have our final answer, and we have the choices above.
The only answer that matches ours is the last one.
Final answer: 9.533
Hope I helped ^_^

Answer:
Right
Step-by-step explanation:
360/4 = 90
90° is a right angle
It’s the mean!
good luck!!
4x - 4y = -36
3x + 4y = 8
7x = -28
/7 /7
x = -4
-4 - y = -9
+4 +4
-y = -5
/-1 /-1
y = 5
(-4 , 5)
