Answer:
D
Step-by-step explanation:
The first equation of System 2 is the first equation of System 1.
The second equation has an x-coefficient of (A-L). The coefficients of x in System 1 are A and L, so (A-L) is their difference. The second equation of System 2 is the difference of the equations in System 1.
__
This is described by Choice D:
The second equation in System 2 is the difference of the equations in System 1. The first equation in System 2 is the first equation in System 1.
Choice A bc sub in 8 for v... 8-8=0/2=0. 12+0=12- so 12=12
Answer: 12
Step-by-step explanation:
a^2 times b^2 =c^2
4^2 times 3^2=c^2
16 times 9=c^2
144=c^2
=
12=c
Answer:
44.4
Step-by-step explanation:
yes
Answer:
Multiply 1/4 ; dividing 4
Step-by-step explanation:
Note that in each number going from left to right, it decreases by dividing 4 each time (or multiplying 1/4)
8/4 = 2 ; 2/4 = 1/2 ; (1/2)/(4) = 1/8 ; etc.
(8)(1/4) = 2 ; (2)(1/4) = 1/2 ; etc.
