Write in complete sentences to explain what a budget is, how to make one, and how to balance it
Answer:
Budget is the name given for the evaluation or speculative calculation of the cost of a work or service to be provided.
Step-by-step explanation:
The definition of a budget normally takes into account two main characteristics: the revenue, that is, the amount collected or available, and the expense, which would be the amount to be spent for the completion or maintenance of something. Budgets are present in various aspects of everyday life, from planning for a renovation of the house, to the amounts that will be earmarked for the maintenance of public government services, which directly or indirectly affect the lives of citizens.
Balancing a budget seems easy, but it requires a lot of self-control and discipline. Some strategies for achieving this balance are: do not spend more than what you earn, do not buy anything on impulse, do not borrow, renegotiate your debts and save on expenses that are superfluous.

write each expression without using the absolute value symbol |14-(x-6)|
THIS IS 15 POINTS PLSSSSSSSSSSSSSS HELP
To start, we need to recognize that absolute value is a way of expressing the magnitude of a number, regardless of its sign. Thus, to get rid of the absolute value, we need to consider the two cases in which the expression can have either a positive or a negative sign.
For the case of a positive sign, we can simply write the expression as: 14-(x-6)
For the case of a negative sign, we can multiply both sides of the equation by -1 to get: -14 + (x-6)
Overall, we can express the expression without the absolute value symbol as:
14-(x-6) or -14 + (x-6)

Isaac has 1.17 pounds of cat food. He uses 0.13 pound of cat food to feed one cat. How Sometimes Isaac has kittens. Each kitten has
1/3
as much cat food as a full-grown cat. How many kittens can Isaac feed with the 1.17 pounds?
Answer:
¨Isaac has 1.17 pounds of cat food. He uses 0.13 pounds of cat food to feed one cat. How many cats can Isaac feed with the cat food he has?¨ the answer is 9
Answer:
9
Step-by-step explanation:
1.17 divided by 0.13
Step #1: 0.13 x 5 = .65
1.17 - 0.65 = 0.52
Step #2: 0.13 x 4 = 0.52
0.52 - 0.52 = 0
Step #3: 5 + 4 = 9.

Find the surface area of the cube shown below.
a. 625 cm2
b. 1121 cm2
c. 726 cm2
The surface area of a solid is the area of its faces. The surface area of a cube is just 6*side length^2 since the faces are the same and the faces are squares. So, we have 6 * 11^2 = 726.

Haddie makes and sells knit scarves. Next week she will pay a $25 fee for the use of a booth at a craft fair. She will charge $12 for each scarf she sells at the fair. Write an expression to determine Haddie's profit for selling s scraves after paying the fee for the use of the booth
Answer:
p = 12s -25
Step-by-step explanation:
You want an expression for Haddie's profit from the sale of s scarves when she has revenue of $12 each and a cost of $25.
ProfitProfit is the difference between revenue and cost. Haddie's revenue from sale of s scarves is ...
revenue = 12s
Haddie's cost is the fee she pays for the booth rental:
cost = 25
Her profit (p) is the difference between these values:
profit = revenue - cost
p = 12s -25

Corinna has $64. She wants to buy a $229 plane ticket. She will save up her earnings from working at the museum where she earns $15 per hour. Which inequality shows the number of hours, n, Corinna must work so that she has a total of at least $229?
A.
n ≤ 10
B.
n ≤ 11
C.
n ≥ 11
D.
n ≥ 10
Good luck i hope you pass <3
Answer:
A. n ≤ 10
Step-by-step explanation:
Corinna wants to buy a $229 plane ticket. She currently has $64, so she needs to save up $229 - $64 = $165. Since she earns $15 per hour, we can set up the equation n * 15 = 165, where n represents the number of hours Corinna needs to work. Solving for n, we get n = 11.1, which we can round down to 11 hours. Therefore, Corinna must work at least 11 hours to save up enough money to buy the $229 plane ticket. Answer choice A is the correct answer.
Note: Rounding down to 11 is not required, as long as we do not round up to 12. Rounded or unrounded, 11 is the smallest integer greater than or equal to 11.1, so it is the minimum number of hours Corinna would need to work to save up enough money for the plane ticket.
