The shoes cost at least 38 dollars.

At least means, greater than or equal to which is represented by the sign

≥

The inequality is given as

NEED HELP ASAPPP!!! Drag each scenario to show whether the final result will be greater than the original
Lemur [1.5K]

Answer:

Greater than the original = 2, 4

Less than the original = 5

Same as the original = 1, 3

Step-by-step explanation:

Let the original value be x.

1. A $30 increase followed by a $30 decrease.

New value =x+30-30=x, it is same as original value.

2. A 20% decrease followed by a 40% increase.

Afer 20% decrease.

New value =x-\dfrac{20}{100}x=x-0.2x=0.8x

Afer 40% increase.

New value =0.8x+\dfrac{40}{100}(0.8x)=0.8x+0.32x=1.12x, it is greater than original value.

Similarly check the other values.

3. A 100% increase followed by a 50% decrease.

New value =x+\dfrac{100}{100}x-\dfrac{50}{100}(x+x)=x, it is same as original value.

4. A 75% increase followed by a 33% decrease

New value =x+\dfrac{75}{100}x-\dfrac{33}{100}(x+0.75x)=1.1725x, it is greater than the original value.

5. 55% decrease followed by a 25% increase

New value =x-\dfrac{55}{100}x+\dfrac{25}{100}(x-0.55x)=0.5625x, it is less than the original value.

Therefore, Greater than the original = 2, 4, Less than the original = 5, Same as the original = 1, 3 .

What is the value of x?<br> 4x+2-(3+3x)=7
PolarNik [594]

Answer:

x= 8

Step-by-step explanation:

Step 1- Distribute into the parenthesis by 1.

4x+2+3(-1)+3(-1)x= 7

Step 2- Simplify.

4x+2-3-3x= 7

Step 3- Add common variables.

(4x-3x)+(2-3)

1x-1= 7

Step 4- Add 1 to both sides.

1x-1= 7

 +1  +1

1x= 8

Step 5- Divide both sides by 1.

1x= 8

1    1

x= 8
