Violet was given a box of assorted chocolates for her birthday. Each night, Violet treated herself to some chocolates. Violet ate 4 chocolates each night and there were originally 24 chocolates in the box. Write an equation for C,C, in terms of t,t, representing the number of chocolates remaining in the box tt days after Violet's birthday.
Answer:
C = 24 - 4t
Step-by-step explanation:
Total chocolate = 24 chocolate
Quantity eaten each night = 4
Let
C = number of chocolate remaining
t = number of days after violet birthday
Number of chocolate remaining = original number of chocolate - 4(number of days after violet birthday)
C = 24 - 4t
For instance, if t = 2
That is, 2 days after violet birthday
C = 24 - 4t
= 24 - 4(2)
= 24 - 8
= 16
Answer: C = 24 - 4t

when compared to the exact value?
A. 1,700
B. 2,000
C. 1,755
D. 1,800
Answer:
1755
Step-by-step explanation:
there are 5280 feet in a mile, and there are 3 feet in a yard. if you divide 5280÷3 that will show you how many yards are in a mile. That will give 1760. Then you choose the number that is closest to that.

The missing number for the given expression is 161. The correct option is A.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the expression is ?+ 145 + 318 = 624. The missing number will be calculated as,
X + 145 + 318 = 624
X = 624 - 145 - 318

which statement is true?
A. function h is a reflection and a translation of function f
B. function h is a horizontal translation of function f
C. function h is a reflection and a dilation of function f
D. function h is a vertical translation of function f
Answer:
C. function h is a reflection and a dilation of functionStep-by-step explanation:
Parent function:
f(x) =2^xTransformed function:
h(x) = -3•2^xTransformation applied:
f(x) → -f(x) = reflection over x-axis = vertical reflectionf(x) → 3f(x) = dilation or vertical stretchCorrect answer choice is:

Question 3. The smallest digit by
which *' should be replaced in
710*95, so that the number formed is
divisible by 3 is:
Answer:
2
Step-by-step explanation:
Given:
710*95
Find the smallest digit by
which * should be replaced, so that the number formed is
divisible by 3
The first step is to add the numbers
7 + 1 + 0 + * + 9 + 5 = 22 + *
Next step is to find the multiples of 3
3 = 6, 9, 12, 15, 18, 21, 24, 27, 30
Step 3:
Since the addition of the digits = 22 + *
Then find a number to add to 22 which gives the next multiples of 3 after 22(that is 24)
24 = 22 + *
* = 24 - 22
= 2
* = 2
Substituting * = 2 into 710*95
We have,
710295
Therefore, the smallest digit by
which * should be replaced, so that the number formed is
divisible by 3 is 2
Check:
710,295 / 3
= 236,765

Answer:
[tex]-7^2 + 5^4[/tex]
Step-by-step explanation:
Essentially, you are seeing how much of each of the same term there is. Add the amount together, and it will be the exponent.
[tex](-7) * (-7) = -7^(1 + 1) = -7^2\\5 * 5 * 5 * 5 = 5^(1 + 1 + 1 + 1) = 5^4[/tex]
Combine the two terms together into an expression. Note that you cannot combine them.
[tex]-7^2 + 5^4[/tex] is your answer.

Why does the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?
Why the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?
Because the absolute value equations behave differently in the different ranges.
For a given absolute value equation (or inequality)
| x - a| = b
We get two equations or inequalities:
x - a = b
x - a = - b
And this is why the solution leads to two equations, this originates in the fact that the parent absolute value function:
f(x) = |x|
Behaves differently if x is positive or negative.
f(x) = x if x > 0f(x) = -x if x < 0If you want to learn more, you can read:
