-45 + 12 is equivalent to 12 - 45.
-45 + 12 comes out to -33.
Answer:
36 degreees
Step-by-step explanation:
JKL = 9x + 18
54 = 9x + 18
36 = 9x
4 = x
6(4) + 12 = 36
We define the variables first:
x = number of male cousins
y = number of females cousins
We write the system of equations:
x + y = 9
x = y-2
We solve the system:
Equation 1:
x + y = 9
(y-2) + y = 9
2y-2 = 9
y = 11/2 = 5.5
Equation 2:
x = 5.5-2
x = 3.5
Answer:
Although physically it does not make sense, mathematically the answer is:
number of male cousins = 3.5
number of females cousins = 5.5
49=-7k is equivalent to D because when you simplify both of them, you get -7=k
