Jessica bought

● one bottle of water for $2

● some hot dogs for $3 each.

● She spent a total of $14.

Which equation represents Jessica’s purchase?

A)
3h - 2 = 14
B)
3h + 2 = 14
C)
2h - 3 = 14
D)
2h + 3 = 14

Answers

Answer: The answer is B.

Step-by-step explanation:

h = amount of hot dogs

c = cost of hot dogs in total

Since, you already know that she bought one bottle of water for $2, she spent $14 in total, and each hot cost $3, you want to figure out how many hot dogs she bought to find the total amount of money she spent to buy hot dogs.

3 x h = c

^ This equation says that you need to multiply the number of hot dogs times the cost of each hot dog to get the total amount she spent to buy hot dogs.  

The correct answer is B

This is because it is $3 PER EACH hot dog which lets you know that 3 is were the variable (h) would go. Then you have to add 2 because she is also purchasing a bottle of water. This will equal $14

Answers

Answer: all this needs is an explanation

Step-by-step explanation: 0.40x we don't know x and there is not enough info to find it. first 327-120=207 so basically x cannot surpass 517.5

the right answer would be 517.4 or less because it mustn't surpass 207 or be equivalent to it. hope this helps

i hope it helps u :-)

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Xavier starts with the integer -10 and multiplies it by a negative integer. Mark the statements below as true or false. If false, explain
why to the right of the statement.
a. The resulting product cannot be greater than-10.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
b. The resulting product must be greater than 0.
c. The resulting product cannot be less than 10.

Answers

Answer:

a. The resulting product cannot be greater than-10. (False)

b. The resulting product must be greater than 0.      (True)

c. The resulting product cannot be less than 10.       (True)

Step-by-step explanation:

Explaining Statement (a):

The integer that is given is -10,

Let it will b multiplied with another negative integers let say (-1). Starting with the smallest one in order to clarify all statement.

So, if the resultant product is represented by x, So:

                                             x = (-10)(-1)

             Using the sign Multiplication rule which is {(-)*(-)} = +

                                            x = 10

While looking at the result It is greater than -10 because 10 is greater than -10 (So, First Statement is False)\Similarly, the resulting product is greater than 0 because 10 is greater than 0 (So, 2nd statement is true)At the end, the minimum integer choose to multiply with the -10 will be -1. It neither be -0.5 because -0.5 is not an integer. Hence answer will never ever be less than 10. (Last statement is True)

Answers

Answer:

The answer is d. 13 1/4 feet PLEASE MARK BRAINLIEST

the 8 feet plus the 4 feet from the 4.5 feet makes 12 feet plus the fractions so 8 inches is 1/4 feet and 8 inches plus 5 inches on the 4.5 feet makes 13 inches which is 13 1/4 feet so 8 3/4 feet + 4.5 feet = 13 1/4 feet

no, he is short 72 roses

Step-by-step explanation:

to find this out, we need to find out the area of the planned garden, we do this by multiplying width by length as shown

18 * 204 = 3,672

then we subtract the number of roses from the planed garden area

3,672 - 3,600 = 72

meaning that we are left with 72 spots missing or without a rose

samantha spent $15.88 at a department store. she spent half as much at the bookstore as she did at the department store. she then spent $12.64 at a restaurant. she now has $33.85 left in her purse. how much did she have to begin with?

Answers

Answer:

39.845

Step-by-step explanation:

this question it is asking how much money she has at the beginning, so to solve this we need to add up the money she spent before and add the money she has left.

1. we are ready to know she already spends 15.88 at the beginning and then she spent half as much as 15.88 so, we have to divide 15.88 by 2.

15.88/2= 7.94

2. now everything is figured out, next, add them together.

15.88+7.94+3.385= 39.845

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.


Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.


Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?

Answers

Answer:Simplificando

5 (2j + 3 + j) = 0

Reordene os termos:

5 (3 + 2j + j) = 0

Combine termos semelhantes: 2j + j = 3j

5 (3 + 3j) = 0

(3 * 5 + 3j * 5) = 0

(15 + 15j) = 0

Resolvendo

15 + 15j = 0

a verdadeira questão é por que o vizinho de Sarah quer dentes de tubarão

Step-by-step explanation:

Mova todos os termos contendo j para a esquerda, todos os outros termos para a direita.

Adicione '-15' a cada lado da equação.

15 + -15 + 15j = 0 + -15

Combine termos semelhantes: 15 + -15 = 0

0 + 15j = 0 + -15

15j = 0 + -15

Combine termos semelhantes: 0 + -15 = -15

15j = -15

Divida cada lado por '15'.

j = -1

Simplificando

j = -1
