Answer:

$x>1/2$

Step-by-step explanation:

$2(4x-3)>-3(3x)+5x$

Expand the brackets.

$8x-6>-9x+5x$

Add -9x and 5x

$8x-6>-4x$

Add 4x and 6x on both sides.

$8x+4x>6$

Add the like terms.

$12x>6$

Divide 12 into both sides.

$12x/12>6/12$

$x>1/2$

Answer:

x > 1/2

Step-by-step explanation:

We have the inequality 2(4x - 3) > -3(3x) + 5x.

Let's first expand all the parentheses on the left side. When doing so, remember that we take the sum of the products of the outside number with each of the inside numbers:

2 * 4x + 2 * (-3) > -9x + 5x

8x - 6 > -4x

Add 4x and 6 to both sides:

8x + 4x > 6

12x > 6

Divide by 12:

x > 6/12

x > 1/2

Thus, any x value greater than 1/2 works: x > 1/2.

Answer:

The first set is a set of linear equations.

The way to figure this out is pretty easy. If you want to see it visually, go search up desmos graphing calculator and put in these equations.

A linear equation is a function that has a constant slope, meaning that the rate it increases or decreases will never change. The first one is a set of linear equations because it is 2 equations with constant slopes, meaning that the slopes will never change no matter what y and x are.

The second set is not, because while the first equation is linear, the second is an inequality. While it is a straight line, it doesn't count as a linear equation.

The third set, both equations have exponents on the x, which means that the slope will change depending on x. This means that both of these are not linear equations.

The only set that is a linear set is the one that has only linear equations.

A store pays a manufacturer $20 for a hat. To make a profit, the store prices the hat 60% higher than the amount they paid. Late

Molodets [167]

Answer:

The clearance price is $17.28.

The clearance price will not give the store any profit.

Step-by-step explanation:

We have been given that a store pays a manufacturer $20 for a hat. To make a profit, the store prices the hat 60% higher than the amount they paid.

The price of the hat after increasing the price by 60% will be:

$\text{Price of the hat after an increase of 60\%}=20+(\frac{60}{100}*20)$

$\text{Price of the hat after an increase of 60\%}=20+(0.60*20)$

$\text{Price of the hat after an increase of 60\%}=20+12$

$\text{Price of the hat after an increase of 60\%}=32$

So, the price of hat after the increase of 60% will be $32.

As the sale reduces the price of hat by 10%, so the price of hat after sale will be:

$\text{Price of the hat after sale of 10\%}=32-(\frac{10}{100}*32)$

$\text{Price of the hat after sale of 10\%}=32-(0.10*32)$

$\text{Price of the hat after sale of 10\%}=32-3.2$

$\text{Price of the hat after sale of 10\%}=28.8$

So the price of hat after 10% sale will be $28.8.

As the clearance sale reduces the price by 40%, so price of hat after clearance sale will be 28.8 minus 40% of 28.8.

$\text{Price of the hat after clearance sale}=28.8-(\frac{40}{100}*28.8)$

$\text{Price of the hat after clearance sale}=28.8-(0.40*28.8)$

$\text{Price of the hat after clearance sale}=28.8-11.52$

$\text{Price of the hat after clearance sale}=17.28$

Therefore, the clearance price is $17.28.

As store has purchased the hat from manufacturer for $20 and sold it $17.28, therefore, the store will not have a profit.

One of the rows in the table has an error and does not have the same ratio as the other rows. Which explains how to correct the

hram777 [196]

Row 1 3 ft 91.44 cm
The ratio is 91.44 cm/ 3 ft = 30.48 cm/ft

Row 2 6 ft 172.88 cm
The ratio is 172.88 cm / 6 ft = 28.81 cm/ft which ius not the same as 30.48 cm/ft.

Row 3 7 ft 213.36 cm

The ratio is 213.36 cm/ 7 ft = 30.48 cm/ft, which is the same as the first ratio.

Since 2 rows have the ratio 30.48 cm/ft, this ratio is correct. The ratio 172.88 cm / 6 ft is incorrect.

6 ft * 30.48 cm/ft = 182.88 cm

Answer: 
B.Row 2 should show 6 feet is equivalent to 182.88 centimeters.
