1: You will pay $682.5 for a item with original price of $1050 when discounted 35%. In this example, if you buy an item at $1050 with 35% discount, you will pay 1050 - 367.5 = 682.5 dollars.

2: You will pay $617.5 for a item with original price of $650 when discounted 5%. In this example, if you buy an item at $650 with 5% discount, you will pay 650 - 32.5 = 617.5 dollars.

Solve the equation for x:
|3x - 2| = 5

Answers

Answer:

x = 1

Step-by-step explanation:

When there is an equation in absolute form like this |3x - 2| that means that there are no negative numbers or subtraction signs. Instead, such things are reversed, so the simplified equation is

3x + 2 = 5

So then we proceed as normal

3(1) + 2 = 5

3 + 2 = 5

5 = 5

Find the number of grams of protein in an 8-ounce serving of vanilla yogurt that contains 179 calories, 3 g of fat, and 31 g of carbohydrate.
g

Answers

Answer:

7 grams of protein

Step-by-step explanation:

C = 9f + 4p + 4c

Plug the given information into the given formula

179 = 9(3) + 4p + 4(31)

Use PEMDAS

179 = 27 + 4p + 124

Combine like terms

179 = 151 + 4p

Subtract both sides by 151 to isolate variable p

179 - 151 = 4p

28 = 4p

Divide both sides by 4 to isolate variable p

28 ÷ 4 = p

7 = p

Answers

Answer:

A = 180 customers.

Step-by-step explanation:

Let the number of customers that made additional purchases be A.

Given the following data;

Percentage = 72% = 72/100 = 0.72

Total number of customers = 250

To find the number of customers that made additional purchases;

A = 0.72 * 250

A = 180 customers.

Therefore, 180 customers made additional purchases on Wednesday.

Answers

Answer:

The answer is below

Step-by-step explanation:

A shop contained some refrigerators and televisions. The total number is 800, and 45% of them were refrigerators. If 60% of refrigerators were sold and 65% of televisions were sold last week. How many fewer refrigerators were sold than televisions?​

Solution:

The number of refrigerators = 45% of 800 = 0.45 * 800 = 360 refrigerators.

The number of televisions = 800 - 360 = 440 televisions.

number of refrigerators sold = 60% of 360 = 0.6 * 360 = 216 refrigerators

number of televisions sold = 65% of 440 = 0.65 * 440 = 286 televisions

The number of fewer refrigerators that were sold than televisions = 286 - 216 = 70

Which number line shows the solution to inequality 3x – 3 < 12?

Answers

Answer:

A

Step-by-step explanation:

The Graph "A" show the value of x in  inequality 3x – 3 < 12

What is inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

What does open circle and close circle shows in graph?

A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".

According to the question

Given inequality 3x – 3 < 12

Solving for x

3x – 3 < 12

3x < 12 + 3

3x < 15

x < 5

Open circle will be used to show the greater than sign

Therefore,

Graph  A shows the inequality .

Hence, the Graph "A" show the value of x in  inequality 3x – 3 < 12

She finds agiant tree and works to pierce its thick bark withher tusks. She is prying and poking to get atthe water the tree often stores inside. This is noordinary tree but a baobab, a tree that looms largein size and importance for both the animals andpeople of Africa The baobabs astonishing appearance alone provesit is special. It can grow up to 60 feet high and30 feet wide, soaring above most other life in thedry savannah. The baobab has a wide barrel-liketrunk topped with shorter, twisted branches. Itonly grows leaves for two short periods, giving thebranches the appearance of gnarled roots for mostof the year. In fact, some African legends say thata god, angry at the baobab, decided to uproot andreplant it upside down. This remarkable tree survives dry conditions andis found in many regions of Africa. Its roots spreadout up to a hundred feet away to gather neededwater. The adaptable sponge-like bark contracts indry months and expands in wet ones. Baobab treesserve as a source of water, food, and a safe homefor a variety of animals. In particular, the whitebacked vulture, with a wingspan of about sevenfeet, nests high in the baobabs branches. The greatbird only nests once a year, laying just one egg. Thetall, strong baobab provides the ideal site for severalmonths of safety for the mother and baby vulture. For centuries, the baobab has also beenessential to the people in various parts of Africa,many of whom call it the Tree of Life. Thebaobabs immense trunk is hollow, creating alarge circular chamber at the center. Baobabchambers have been used as shelters, prisons,and animal stables. The trees spinach-likeleaves can be eaten, and people use them forboth food and medicine. The fruit providesa citrus-like refreshment. People strip off thefibrous bark to make rope, cloth, roofing, andpaper. Unlike most other trees, the baobab canendure this practice, regenerating its bark andcontinuing to grow. Perhaps this is one reason baobabs have suchincredible longevity. Some have even beenknown to live for over 2,000 years!
