Who's Weggy?

2x + 3y = 40

-2x + 2y = 20

These are set up so we can just add them for the solution:

5y = 60

y = 12

2y-20=2x

x=y-10=2

Answer: x=2, y=12

Answer:

The value of x is 49 and the value of AB is 90

Step-by-step explanation:

You know that AB and DE are congruent. That information is given to you.

You set the equations equal to each other and then solve.


2x - 8 = x + 38


Subtract x


x - 8 = 38


Add 8.


x = 49


Plug back into 2x - 8 to find the value of AB


2 times 49 - 8


98 - 8


90

Resale Value Garland Mills purchased a certain piece of machinery 2 years ago for $500,000. Its present resale value is $420,000
Natasha2012 [34]

Answer:

260,000

Step-by-step explanation:

The value decreases by 40,000 per year (500000-42000/2 years) the value will decrease by 240000 in six (4 years plus 2 years already passed) years. 6 x 40,000 =240000

So, the value should be 260,000 (500000-240000)

Or

year 1 500000-40000=460000

year 2 460000-40000=420000

year 3 420000-40000=380000

year 4 380000-40000=340000

year 5 340000-40000=300000

year 6 300000-40000=260000
