Answer:
B.) (-202)+(-12)
Step-by-step explanation:
The undersea level is negative then going under again will produce a completely negative answer.
4x+6 = 5x-6
x=12
4(12)+6=54
The answer is 54 (The paper says C is 54, not 55)
Answer:
m = -24
Step-by-step explanation:
(m/6) - 7 = -11
Add 7 to each side
(m/6) - 7+7 = -11+7
m/6 = -4
Multiply each side by 6
m/6 *6 = -4*6
m = -24
5x+y = -23
by substitution
A)
5(-3) + (-4) = -23
-15 - 4 = -23
-19 = -23
Wrong
----------------
B)
5(-5) -3 = -23
-25 - 3 = -23
-28 = -23
Wrong
-----------------
C)
5(-4) - 3 = -23
-20 - 3 = -23
-23 = -23
