Answer:
answer of 2a)
He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then
24–16=a
His new account balance is $8.
He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then
8+b=28
His deposited $20 in his account.
He has $28 and spent $34. Let c represent his account balance after he bought the book. Then
28–34=c
His new account balance is -$6.
He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then
−6+d=0
He deposited $6.
answer of 2b)
If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Step-by-step explanation:
you're going to have to set up two expressions since it's an absolute value problem
Answer:
(a/2) ^4 or a^4/16
Step-by-step explanation:
(8a^-3)^-4/3
split into two parts
8^ -4/3 * (a^-3)^-4/3
using the power to the power rule we can multiply the exponents
8^(-4/3) *a^(-3*-4/3)
8^ (-4/3) * a^(4)
replace 8 with 2^3
(2^3)^(-4/3) * a^(4)
using the power to the power rule we can multiply the exponents
2^(3*-4/3) * a^(4)
2 ^ (-4) * a^4
the negative exponent means it goes in the denominator if it is in the numerator
a^4/2^4
make a fraction
(a/2) ^4
or a^2/16

Answer:
my ans will be wrong also and right also 50%5$chances it is an opposite angle so it is in out manner so iys sum is 180 so we have to subbtract
Step-by-step explanation:
65०to 180०(180०-65०=115०) i think ans is 115०the missing angle measurement is 115०in my opinion
