Anthony borrows $6.50 from a friend to pay for a sandwich and drink at lunch,
Then he borrows $3.75 from his sister to pay a library fine,
Choose an equation to express Anthony's total debt that day.
What is the answer. If it's correct I will give a heart, many points, 5 review stars, and brainliest ok.
Answers
Answer:
C: -$6.50 + (-$3.75) = -$10.75
Step-by-step explanation:
Anthony owes his friend $6.50, so he has -$6.50
Anthony owes his sister $3.75, so he has -$3.75
Add up the debt to figure out how much debt he has!
-$6.50 + (-$3.75) = -$10.75
however, because this is asking about total debt, it is NOT C.
the total debt (-) is $10.75, which is represented in answer D. this means he owes $10.75if you choose C, the total debt (-) for -$10.75 would actually be positive. think about it like if you have a negative negative, you get a positive, so C would actually be credit.comment or message me if you have any questions :)

How would we know the gcf of 4xy+8x^2y-24x^4y^5
Answers
9514 1404 393
Answer:
4xy
Step-by-step explanation:
List the prime factors of each term.
4xy = 2·2·x·y8x^2y = 2·2·2·x·x·y24x^4y^5 = 2·2·2·3·x·x·x·x·y·y·y·y·yIdentify a factor that appears in each list. Cross it off of each list and add it to your list of "output" factors. Repeat until you run out of factors that appear in all of the lists.
You should quickly determine that all of the factors of 4xy appear in both other lists. That is the GCF. When you have exhausted the factors of 4xy, there are no more possible common factors.
GCF = 4xy
Then the expression can be factored as ...
= 4xy·(1 +2x -6x^3y^4)
_____
Additional comment
If you use exponents to simplify writing repeated multiplication, you will find that the GCF has the factors with the lowest exponent. Here, the lowest power of 2 is 2^2 in 4xy; the lowest exponents of x and y are 1, also in that term.

What are Algebraic Identities?Algebraic identities are equations in which the right-hand side of the equation's value is exactly equal to the left-hand side of the equation's value. Any value for the variables satisfies them. To further comprehend this, let's look at an illustration.
(a + b)² = a² + 2ab + b²(a - b)² = a² - 2ab + b²(a + b)(a - b) = a² - b²(x + a)(x + b) = x² + x(a + b) + abgiven:
11a²– 15b²
Using the identity
(a² - b²)= ( a+ b)(a- b)
so, 11a²– 15b²
[(√11a)²– (√15b)²]
= (√11a - √15b) (√11a + √15b)
Hence, the difference can be displayed as (√11a - √15b) (√11a + √15b).

To solve this equation, use PEMDAS:
P - Parentheses
E - Exponents
M/D - Multiplication/Division
A/S - Addition/Subtraction
PEMDAS is the method that is used for the order of operations. Multiplication and division are interchangeable, so when there are only those signs left, you solve from left to right. This also applies to addition and subtraction.
Equations must always be solved in the order of PEMDAS -- P, then E, then M/D, then A/S.
Now, to solve the equation:
100 - 2(12 + 13) First, solve what is in the parentheses (P).
100 - 2(25) Next, multiply 2 × 25 (M).
100 - 50 Finally, subtract 50 from 100 (S)
50
100 - 2(12 + 13) = 50

The formula for this equation is

a is the final result
p is the starting amount (deposited)
r is the interest rate
n is the number of times it's compounded
t is the time
because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117

Dependent output- distance
“0,__,180,__,216”
*Fill in the blank*
WRONG ANSWERS GET REPORTED!!!
Answers
Answers:
First Blank = 54Second Blank = 162=============================================
Explanation:
The first blank represents the distance that corresponds to t = 1 hour.
We'll replace t with 1 to get...
d = 54t
d = 54*1
d = 54
Therefore, 54 goes in the first blank. It means that Isaac traveled 54 miles after 1 hour.
------------------
We repeat these steps for t = 3
d = 54*t
d = 54*3
d = 162
This means he traveled 162 miles after 3 hours
So 162 goes in the second blank
-------------------
Side note: your teacher wrote 180 but s/he should have written 108 instead because 54*2 = 108
