How many solutions are there to the equation below 3x-10(x-2)=13-7x

Mathematics

katen-ka-za [31]3 years ago
4 0

Answer:

The equation has only one solution

Step-by-step explanation:

we have

x-10(x-2)=13-7x

Solve for x

Distribute in the left side

Remember that

(-1)(-1)=+1

x-10x+20=13-7x

Combine like terms in the left side

-9x+20=13-7x

Adds 9x both sides

20=13-7x+9x

20=13+2x

Subtract 13 both sides

20-13=2x

7=2x

Divide by 2 both sides

3.5=x

Rewrite

x=3.5

Therefore

The equation has only one solution

Under the last-in, first-out (LIFO) inventory valuation method, a price index for inventory must be established for tax purposes
frosja888 [35]

Answer:

The laspeyres method of weighted aggregate price index is used of LIFO inventory valuation, therefore laspeyres index number is 106.08

Step-by-step explanation:

First of all we would have to perform the following table:

                                             

Product   Ending Inventory(Q0)  Begining(P0)   Ending(P1)   P0×Q0   P1×Q0  

    A                    500                         0.15               0.21                75        105

    B                       50                         1.60               1.80                 80         90

    C                       100                        4.50             4.20                 450      420

    D                       40                          12.00          13.40                 480     536

                                                                                             Total  1085     1151

Therefore, using laspeyres index number, we calculate the following:

laspeyres index number=(∑P1×Q0/∑P0×Q0)×100

laspeyres index number=(1151/1085)×100

laspeyres index number=106.08

luda_lava [24]

Answer:

$50 - d = $22.50

Step-by-step explanation:

Since she's receiving a change, it means that d is smaller than $50, therefore, it will be deducted from it to give the change.

What is this just tell me what the L AND W ='s please
andreyandreev [35.5K]
You didn't show us much of the page with the question on it,
so we can't be sure of exactly what you're working on in math.

If you're working with things like squares and rectangles, then
'L' and 'W' are often used to represent the Length and Width of
shapes drawn on paper, or even Length and Width of 3D objects
like blocks or boxes.
