Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Answer = 2x - 30

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.

u = 1.85

Answer:

C. His estimate is incorrect; it should be closer to 12 than 11.

Step-by-step explanation:

1. 11^2 is 121, √(140^2) is 140, and 12^2 is 144.

2. Based off these numbers 140 is closer to 144, meaning that √(140) is closer to 12 than 11.

Therefore, the correct answer is C. His estimate is incorrect; it should be closer to 12 than 11.

Answer:

[tex]2~2/9[/tex] gallons per minute

Step-by-step explanation:

If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.

We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!

The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].

So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.

The quantity of water that drains out of the tub each minute is 2.23 gallons.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.

2¹/₄ minuts = 5 gallons

1 minute = 5 / 2¹/₄

1 minute = 5 /2.25

1 minute = 2.23 gallons

Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

Step-by-step explanation:

Conversion a mixed number 2 2/5 to a improper fraction:-

=> 2 2/5 = 2 × 5 + 2 = 12/5

To find new numerator:

a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5

= 10/5

b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12

c) Write a previous answer (new numerator 12) over the denominator 5.

Two and two fifths is twelve fifth

Multiple:

= 12/5 × 5/7

= 12 × 5/5 × 7

= 60/35

= 12 × 5/7 × 5

= 12/7

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(60, 35) = 5. In the next intermediate step, , cancel by a common factor of 5 gives 12/7

12/7 in mixed fraction is 1 5/7
