How would you choose to reduce the system shown to a 2 × 2? Explain why you would choose this approach.
Answer:
hello the system related to your question is missing below is the system
–3x + y – 2z = 10 --------(1)
5x – 2y – 2z = 12 -------- (2)
x – y + z = 23 ----------- (3)
answer :
To reduce the system above to a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires X and either Y or Z
Step-by-step explanation:
Given system :
–3x + y – 2z = 10 --------(1)
5x – 2y – 2z = 12 -------- (2)
x – y + z = 23 ----------- (3)
To reduce the system above to a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires X and either Y or Z
Eliminating X is not the best way
solving equation 1 and 2
substrate equation (1 ) from equation (2) to eliminate Z
= 8x - 3y = 2
multiply equation (3) by 2 then substrate equation (2) from (3) to eliminate Y
2x - 2y + 2z = 46
-( 5x - 2y - 2z )= 12
= -3x + 4z = 34
What is the value?

A triangle has side lengths of (8w-5)(8w−5) centimeters, (9w-6)(9w−6) centimeters, and (3x-7)(3x−7) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
a. 6w-4x
b. −11−4x+17w
c. 3x+17w−18
d. 3w+3−4x
Answer:
The answer is 3x + 17w - 18
Solve for d.
26 = 100d
d= 26
d= 0.26
d= 2.6
d= 0.026

4x + 3y = 5
Answer:
x=2 and y=−1
Step-by-step explanation:
Let's solve your system by substitution.
4x+3y=5;2y=x−4
brainliest please?
Answer:
The answer to the system of equations is x = 2 and y = -1
Step-by-step explanation:
We can substitute the variables and see how they work with the equations.
2 (-1) = (2) - 4
-2 = 2 - 4
-2 = -2
4 (2) + 3 (-1) = 5
8 + (-3) = 5
8 - 3 = 5
5 = 5

Answer:
I know that a= 124 but I'm afraid I don't know how to solve b. I thought I'd put down half an answer anyway incase that helps.
Step-by-step explanation:
The exterior circle angles all have to add up to 360 degrees so all you have to do is subtract 100 and 136 from 360 and you get 124 for a.
