Answer:
x = 2, y = -1
Step-by-step explanation:
Now change the equation,
→ x + y = 1
→ y = 1 - x
Then the value of x will be,
→ 2x + y = 3
→ 2x + 1 - x = 3
→ x = 3 - 1
→ [ x = 2 ]
Therefore, the value of x is 2.
Now value of y will be,
→ y = 1 - x
→ y = 1 - 2
→ [ y = -1 ]
Hence, the value of y is -1.
69×2 [8+12-10×2+ (7-5) -1] -6
69×2 [8+12-10×2+2-1] -6
69×2 [8+12-20+2-1] -6
69×2 [20-20+2-1] -6
69×2 [0+2-1] -6
69×2 [1] -6]
138 [1] -6
138-6
132
I believe this is ur answer.
L would measure at 54°. Because the angels of a triangle measure up to 180, you can set the equation up like this: 5x + 3x + 2x = 180. These are like values, so you can add them together to simplify a bit, yielding 10x = 180. Divide 180 by 10 to get x by itself, giving you 18. L = 3x, so 3(18) = 54.
Answer:
show the graph of domain and range
Answer:
Number of offices to be cleaned to cover the cost of equipment =15
Cost of equipment =$.315 Cost of supplies =$.4 Charge per office =$.25
Number of offices to be cleaned to cover the cost of equipment =x
Then -25x − 4x =315
21x =315
x=315
21=15
Number of offices to be cleaned to cover the cost of equipment =15
