Solve for n:
6n − 2(4n + 7) + 4 = -2
A:-6
B:-4
C:4
D:6
Answers
Answer:
B
Step-by-step explanation:
6n - 2(4n + 7) + 4= -2 firstly you open the bracket
6n - 8n - 14 + 2 = -2 then you collect the like terms
6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient
-2n= 12 - 4
-2n = 8
= n = 8 ÷ -2
n = -4

is (1 , 2) the solution to the following system of equations?
Answers
Answer:
Yes this is a solution to the system of equations.
Step-by-step explanation:
What you do is you have to make sure that 1 and 2 are both real numbers, then you substitute the 7 for the first equations and the 14 from the second equation, and put the 2 there instead. Because you used the Y as the 7 in the first equation you can get rid of the Y in the equation and get X = 2, and you just check to make sure that 2 is included in the ( ). You are welcome :)

George has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money. Look at the numerical expression George used:
15 − 9 + 2.65 + 1.35 + 2(1.74)
Can you help him determine why he does not have enough money?
Answers
Answer:
He doesn't have enough money because the total of things he wants to buy is more than the money he has.
Step-by-step explanation:
9 + 2.65 + 1.35 + 2(1.74) must be less than or equal to 15. However all of this added together equals $16.48. This means that he doesn't have enough money.
Answer:
The total price of the items he wants to buy is $1.48 over the amount of money he has.

which is greater? -5.7 or -5 2/5
Answers
Answer:
-5 2/5
Step-by-step explanation:
we know that 2/5 is 0.4 so
it is -5.4
-5.4 is greater than -5.7
when u put -5.7 in fraction form it is - 5 7/10 and to make it easier to compare u can change -5 2/5 to -5 4/10. Because it is in negatives, (think about the number line) -5 2/5 is greater. hope this helps

I need help plz. Binary math
Answers
========================================================
Explanation:
Whenever you have a series of nothing but '1's like this, the base 10 equivalent is always going to be 1 less than a power of 2.
The number will be of the form [tex]2^n-1[/tex] where n is a nonnegative integer.
If you're familiar with the list of powers of 2, then you'll likely realize that 64 is a power of 2 since [tex]2^6 = 64[/tex]. One less than this is [tex]2^6-1 = 64-1 = 63[/tex]
This leads to choice A as the answer.
The other answer choices are not one less than a power of 2, so we can cross those off the list.
------------------------------
Further explanation:
Each slot in the binary number given represents a power of 2. We multiply those '1's by a power of 2 and add them up like so
1*(2^5) + 1*(2^4) + 1*(2^3) + 1*(2^2) + 1*(2^1) + 1*(2^0)
1*32 + 1*16 + 1*8 + 1*4 + 1*2 + 1*1
32 + 16 + 8 + 4 + 2 + 1
63
Summing the first n powers of 2 leads to the result [tex]2^{n}-1[/tex]
So, summing the first 6 powers of 2 leads to [tex]2^n-1 = 2^6-1 = 63[/tex]
