Answer:
2x-y=-27 in standard from
Step-by-step explanation:
This angle will be smaller than 108*. So when we know it will be multiplied by 2 C and D are automaticly marked off.
A or B. 36 times 2 = 72 72 times 2 = 144.
If we look at the angles they are less than 90* so our answer would be A. 36*.

Given :-
To find :-
Solution :-
<u>According</u><u> to</u><u> Question</u><u>,</u>
- x = 3 + √8
- 1/x = 1/3-√8
- 1/x = 1(3+√8)/(3+√8)(3-√8)
- 1/x = 3+√8/3²-(√8)²
- 1/x = 3+√8/9-8
- 1/x = 3 + √8
<u>So </u><u> </u><u>that</u><u> </u><u>,</u>
- x² + 1/x²
- (x + 1/x)² - 2
- ( 3+√8+3-√8)²-2
- 9² - 2
- 81 - 2
- 79
432-240=192
192 is the amount of shoes produced in 4 hours
194/4=48
48 is the amount of shoes products per hour

The <u>new system</u> of equivalent equations are 4x + 6y = 8 and 12x + 3y = 1
To get an equivalent equation, we multiply the original equation by a constant and replace it with the new equation.
So, 2x + 3y = 4 (1)
12x + 3y = 1 (2)
We multiply equation (1) by 2
So, 2x + 3y = 4 (1) × 2
⇒4x + 6y = 8 (3)
Replacing (1) by (3), we have
4x + 6y = 8 (3)
12x + 3y = 1 (2)
So, the <u>new system</u> of equivalent equations are 4x + 6y = 8 and 12x + 3y = 1.

The <u>new system</u> of equivalent equations are 3x - 21y = 24 and 5x + 4y = 20
To get an equivalent equation, we multiply the original equation by a constant and replace it with the new equation.
So,
x - 7y = 8 (1)
5x + 4y = 20 (2)
We multiply equation (1) by 3, we have
So, x - 7y = 8 (1) × 3
⇒3x - 21y = 24 (3)
Replacing (1) by (3), we have
3x - 21y = 24 (3)
5x + 4y = 20 (2)
So, the <u>new system</u> of equivalent equations are 3x - 21y = 24 and 5x + 4y = 20.
