A store pays $42.00 for a pair of shoes and marks the price up by 50%. What is the selling price? A $63.00 b $76.00 c $84.00 d $37.00

Answers

Answer:

63.00

Step-by-step explanation:

Increasing a price by 50% is like adding half of the original price to get an updated price. 42 times 50% or divided by 2 (Since it produces the same result) is 21 and 21 plus 42 is 63. 63 dollars is the correct answer which means the correct option is option A.

Answer: 84

Step-by-step explanation: do 42 dived by 50% gets you 84

Solve for x.
-2x-3=-7

add 3 to both sides

-2x=-4

isolate x by diving both sides by -2

Answer: x=2

Hope that helps!

Please mark brainliest

Answer:

x = 2

Step-by-step explanation:

The whole goal when solving problems like this is to get the x alone. So the first step would be to get the -3 over to the other side. To do this, you would add 3 to each side of the equation, so that the -3 on the left side cancels out.

-2x - 3 = -7

+3 +3

-2x = -4

The next thing you need to do is divide each side by -2. You would do this because right now, the equation reads "negative two times x equals negative four". When you divide a multiplication problem, it cancels out, so you are left with just the x.

-2x = -4

÷ -2 ÷ -2

x = 2

You now have the value of x.

Write 3-5 sentences about the process of the Sums and differences of cubes Factoring Method

Answers

Answer:

nah nah mane 12

Step-by-step explanation:

Answer:

Step one: Decide if the two terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the two terms only have a 1 in common which is of no help.

Step 2: Rewrite the original problem as a difference of two perfect cubes.

Step 3a: “Write What You See” If you disregard the parenthesis and the cubes in step 2, you should see:

Step 3b: “Square-Multiply-Square” If you square the first term, x, you get x2. If you multiply the two terms, x and 4, you get 4x. Finally, if you square the second term, 4, you get 16.

Step 3c: “Same, Different. End on a Positive” This will determine the signs of the problem. The first sign should be the same as the original question, the next sign should be different then the first, and the last sign should always be positive.

Step 4: Write the final answer.

Una garrafa de aceite equivale a 5 botellas y 3 garrafas es igual a 7, las cuales suman 11 litros, ¿Cuál es las capacidad de una botella y una garrafa?

Respuesta:

Botella, B = 0.5

Jarra, C = 2,5

Explicación paso a paso:

Dejar :

Garrafa = C

Botella = B

C = 5B - - - - 1)

3 garrafas más 7 botellas = 11 litros

3C + 7B = 11

C = 5B

3 (5B) + 7B = 11

15B + 7B = 11

22B = 11

B = 11/22

B = 1/2 = 0,5

Sustituyendo B = 0.5 en 1)

C = 5B

Tamika makes $ 378.00 on the sale of a home theater system that costs $9.000.00. Express her rate of commission as a percent rounded to the nearest whole number

Answers

Answer:

Step-by-step explanation:

commission rate = (amount earned on sales / total cost of items sold) x 100

[tex]\frac{378}{9000}[/tex] × 100 = 4.2%

To convert to the nearest whole number, look at the first number after the decimal,

if it is equal to or greater than 5, add 1 to the number before the decimalif it is less than five, add 0 to the number before the decimal

two is less than 5, thus we would add zero to 4.

4.2% becomes 4%

N a typical 2-pound bag of M&Ms contains 500 individual pieces, of which... 120 are blue, 70 are brown, 80 are green, 100 are orange, 60 are red, and 70 are yellow. If I randomly select one M&M candy from the bag, what is the probability that candy will be red?

Answers

Answer:

0.12

Step-by-step explanation:

Number of red candies = 60

Total number of candies = 500

Recall :

Probability of event A = number of occurrences of A / total number of occurences

= required outcome / Total possible outcomes

The probability of randomly selecting a red candy is :

= number of red candies / total number of candies

= 60 / 500

= 0.12

Just a poem. No biggie.The Darkness Is A Friend ~ T.H.McGalliardI used to be afraid of the dark,And what might be lurking in it,Monsters that'd eat me,Demons ready to steal my soul,But over the years my fear lessened,It became more welcoming,Like a warm hug when you're cold,But it shouldn't have,I preferred the dark because it hid my tears,No one could see the anguish on my face,The lifelessness in my eyes,No one could see my body shake,With muffled sobs in my pillow,Slowly I fell for the darkness and its inhabitants,The demon in my closet became a vent,Who I'd tell my deepest secrets too,The monster under my bed would hold my hand,When I was falling apart once again,The darkness I had once feared,Became a friend.
