Step-by-step explanation:

Let the number be x.

ATQ,

Malachy halves the number and gets an answer of 67.3.

$\dfrac{x}{2}=67.3$

This the equation for the given statement.

It can also be written as :

$x=2\times 67.3\\\\x=134.6$

Hence, this is the required solution.

Please help solve -2|5y-1|=-10

sweet-ann [11.9K]

Alright, so we can start by dividing -2 from both sides, getting |5y-1|=20. Then, since 5y-1 is in an absolute value, 5y-1 is either 20 or -20.
In 5y-1=20, we can add one to both sides, getting 5y=21 and y=21/5. In
5y-1=-20, we can add one again, getting 5y=-19 and y=-19/5.

If you have any more equations, make sure to plug both numbers in to check, but otherwise y has two answers , which are -19/5 and 21/5.

The best way to solve this is to put it into a proportion:
$\frac{x}{84} = \frac{ \frac{1}{4} }{ \frac{3}{4} }$
So you cross multiply to get:
$21= \frac{3}{4} x$ (the 21 is from $\frac{1}{4}$ •84)
Then multiply by $\frac{4}{3}$
And you get $28, so the reduced price would be $28.

A company sells its printers to customers in order to make a profit of 25% calculate the price the company paid for a printer wh

ioda

The company paid $2000 for the printer

Step-by-step explanation:

Let x be the price of the printer for which the company bought it.

If x is the price of printer, then 25% of x will be the profit made by the company.

That is:

0.25x

According to the statement,

The cost and profit earned by company are equal to 2500

So,

$x+0.25x = 2500\\1.25x = 2500$

Dividing both sides by 1.25

$\frac{1.25x}{1.25} = \frac{2500}{1.25}\\x = 2000$

Hence,

The company paid $2000 for the printer

Answer: labor force participation rate =60%

unemployment rate = 6.67%

Step-by-step explanation:

The labor force participation rate is computed as

$\text{labor force participation rate}=\dfrac{\text{Total employed persons}}{\text{Total population}}$

i.e. $\text{labor force participation rate}= \dfrac{72000}{120000}$

$= 0.6\ or\ 60 \%$

The unemployment rate is computed as:

$\text{unemployment rate}=\dfrac{\text{Number of personsdon't have jobs }}{\text{Total population}}\\\\\text{unemployment rate}=\dfrac{8000}{120000}\\\\\text{unemployment rate}=0.0667\ or\ 6.67\%$

Hence, labor force participation rate =60%

unemployment rate = 6.67%
