Put it to the first equation
[tex]\dfrac{1}{4\!\!\!\!\diagup}\cdot\dfrac{4\!\!\!\!\diagup}{3}+y=1\\\\\dfrac{1}{3}+y=1\qquad|\text{subtract}\ \dfrac{1}{3}\ \text{from both sides}\\\\y=\dfrac{3}{3}-\dfrac{1}{3}\\\\y=\dfrac{3-1}{3}\\\\y=\dfrac{2}{3}[/tex]
HELLo the attachment show the question dont answer if you dont know
I need help plz. Binary math
========================================================
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]

Step-by-step explanation:
A grocery store sells bags of oranges in two different sizes.
The 3-pound bags of oranges cost $4.
The 8 pound bags of oranges cost $9
Which Oranges cost less per pound? Explain or show your reasoning.
The 8-pound bags of oranges cost less per pound than 3-pound bags because the cost for 1-pound bag of oranges is 1.125 (this was taken from $9 divided by 8-pound). The cost per 1-pound bag of oranges ($4 divided by 3-pound bags) is 1.33...
f(x)=2/3x−1 and g(x)=−4x+6. What transformation occurs from function f to function g?
Answer:
vertically stretched by multiplying each of its y-coordinates by 6, and is followed by a reflection across the x-axis.
Step-by-step explanation:
[tex]f(x)=\dfrac{2}{3}x-1\qquad|\text{multiply both sides by (-6)}\\\\-6f(x)=-6\cdot\dfrac{2}{3}+(-6)(-1)\\\\-6f(x)=-4x+6\\\\-6f(x)=-(4x-6)[/tex]

Find the missing measures
Answer:
Step-by-step explanation:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Solve for n:
6n − 2(4n + 7) + 4 = -2
A:-6
B:-4
C:4
D:6
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

Answer:
x = -7
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
6(-x - 3) = 24
Step 2: Solve for x
Divide 6 on both sides: -x - 3 = 4Add 3 on both sides: -x = 7Divide -1 on both sides: x = -7Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(-(-7) - 3) = 24Multiply: 6(7 - 3) = 24Subtract: 6(4) = 24Multiply: 24 = 24Here we see that 24 does indeed equal 24.
∴ x = -7 is the solution to the equation.

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?
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.

Answer:
x = 6
Step-by-step explanation:
-(x - 8) = 2
multiply the negative
-x + 8 = 2
subtract 8 from both sides
-x = -6
x = 6
Answer:
x = 6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-(x - 8) = 2
Step 2: Solve for x
Divide both sides by -1: x - 8 = -2Add 8 on both sides: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -(6 - 8) = 2Subtract: -(-2) = 2Multiply: 2 = 2Here we see that 2 does indeed equal 2.
∴ x = 6 is the solution to the equation.

is (1 , 2) the solution to the following system of equations?
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 :)
