A machine that originally cost 15 600 has a value of 7500 at the end of 3 years the same machine has a value of 2800 at the end

sladkih [1.3K]

A) The rate for the first 3 years :

15,600 - 7500 = 8100

8100/3 years = 2,700 per year depreciation.

B) The rate between 3 and 8 years:

7500 - 2800 = 4700

4700 / 5 year = 940 per year depreciation.

C) the value of the machine depreciated at a higher rate in the first 3 years. After the first 3 years, the depreciation rate decreased.

Find the solution of the system of equations.<br> 10x+10y=40 <br> 5x+3y=8

ddd [48]

Answer:

x = -2 & y = 6

Step-by-step explanation:

$10x+10y=40$

$10x+10y+ -10y=40+-10y$

$10x=-10y+40$

$\frac{10x}{10} =\frac{-10y+40}{10}$

$x=-y+4$

$5x+3y=8$

$5(-y+4)+3y=8$

$-2y+20=8$

$-2y+20+-20=8+-20$

$-2y=-12$

$\div2$

$y=6$

$x=-y+4$

$x=-6+4$

$x=-2$

Hope this helps.

Melissa and Emily are playing at the pool.They have three different measuring jars for; liters, cups, and pints. They find that

Alekssandra [29.7K]

Answer:

Here is the missing part.

Cups and liters:-1 litre = 2.1 cups

Cups and pints:- 1 pint = 2 cups

Pints and liters:-1 litre = 2.1 pints

Step-by-step explanation:

Step 1:

7 cups + 3 liters = 9.8 pints

$7c+3l=9.8p$

5 liters - 9 cups = 6 pints

$5l+9c=6p$

Cups and Liters

$7c+3l=9.8p$

$p= 7c+3l/9.8$ (put in equation 2)

$5l-9c= 7c+3l/9.8\\49l-88.2c=7c+3l\\49l-3l=7c-88.2c\\46l=45.2c$

1 Liter = 2.1 Cups.

Step 2:

Cups and Pints

$7c+3l=9.8p\\3l=9.8p-7c$

$l=9.8p-7c/3$ (put in equation 2)

$5(9.8p-7c/3)-9c=6p\\(49p-35c/3)-9c=6p\\49/3p-35/3c-9c=6p\\49/3p-6p=35/3c+9c\\31/3p=62/3c$

1 Pint = 2 Cups.

Step 3:

Pints and Liters

$7c=9.8p-3l$

$c=9.8p-3l/7$ (put in equation 2)

$5l-9(9.8p-3l/7)=6p\\5l-63/5p+27/7l=6p\\5l+27/7l=6p+63/5p\\62/7l=93/5p$

1 Liter = 2.1 Pints.
