ANSWER

STEP-BY-STEP EXPLANATION
Given information

To estimate the above expression, we need to find the factors of the denominators to get the LCM
Factors of 12 = 2 x 2 x 3
Factors of 8 = 2 x 2 x 2
From the above factors, the LCM is 2 x 2 x 2 x 3 = 24
Therefore, LCM is 24
Subtracting mx from both sides, we get y-mx=b
Answer:
x = 14.5
Step-by-step explanation:
Exterior angle thm
<C = <D
7x - 2 = 9x - 31
7x - 9x = -31 + 2
-2x = -29
x = 14.5
Answer:
B.21.3 is the correct answer
Step-by-step explanation:
1/2*x+1/4*x=16
x/2+x/4=16
2x+x/4=16
3x/4=16
3x=16*4
3x=64
x=21.3

The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:

Let

Putting value of y from eq(1) into eq(2)



So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.
