This equation has no solution where 'a' and 'b'
are both non-zero real numbers.

You said                                 2a + 2b = 2a

Subtract 2a from each side:         2b = 0

'b' must be zero.

And it doesn't matter what the value of 'a' is.
As long as b=0, 'a' can be any number.

Question 3 (25 points) Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50. She retur
cupoosta [38]

The system of equations that represent the cost of x shirts, and y pairs of pants are 4x + 3y = 85.50 and 3x + 5y = 115.00. Option (a) is correct.

A system of equations or an equation system is a collection of simultaneous equations.

Given that Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50 and She returns the next day and buys three shirts and five pairs of pants for $115.00

Now we have to find the system of equation

Lisa buys her children four shirts and three pairs of pants for $85.50 is given by

4x + 3y = 85.50

She buys three shirts and five pairs of pants for $115.00 is given by

3x + 5y = 115.00

Therefore the system of equations that represent the cost of x shirts, and y pairs of pants are

4x + 3y = 85.50 and 3x + 5y = 115.00

Apex Fitness Club uses straight-line depreciation for a machine costing $24,600, with an estimated four-year life and a $2,500 s
Brums [2.3K]

Answer:

machine's book value at the end of its second year = $13550

the amount of depreciation for each of the final three years = $3833.33

Step-by-step explanation:

machine costing $24,600

4 year salvage value = $2,500

3 year salvage value = $2,050

to find out

machine's book value at the end of its second year and the amount of depreciation for each of the final three years

solution

first w calculate depreciate basis = machine costing  - 4 year salvage value

depreciate basis = $24600 - $2500 = $22100

and depreciate = $22100 / 4 = $5525 per year

so after 2 year depreciate value is 2 × $5525 = $11050

now we can say machine's book value at the end of its second year = machine costing -  after 2 year depreciate value

machine's book value at the end of its second year = $24,600 - $11050

machine's book value at the end of its second year = $13550

and the amount of depreciation for each of the final three years = ( book value - salvage value ) / 3

the amount of depreciation for each of the final three years = ( $13550 - $2,050 ) / 3

the amount of depreciation for each of the final three years = $3833.33

Use mental math to determine the solution to x/3 = 24
Rudik [331]
Since this is division problem, lets reverse it into a multiplication problem to figure out x.
24 x 3 = 72. 
x = 72............... 72/3 = 24.
