Proper inverse operation 14 + 17 = 31

Answers

subtraction is the correct inverse operation because you want one number on one side and the others on the other side and since both 14 and 17 are positive you need to subtract to get them to the right side

Answer:

No inverse operation needed. There are no varables to solve for.

How do I solve for x? I tried using law of sines and law of cosines but the angles and sides don't match up.

Answers

Law cosines: $y^(2) =$ 16 + 256 - 128 $√(3) ;$ => y ≈ 16.51;
Law sines: 16/sinx = 16.51/sin30 => sinx = 0.48 => x ≈ 29 degrees;

The cost of 6 sailor moon comic books is equal to the cost of a Nirvana vinyl plus 3 comic books. The vinyl costs $15. How much is one comic book?

Answers

Answer:

one comic book costs $5

Step-by-step explanation:

let cost of comic book = $x

let cost of vinyl = $y

according to the question:

6x = y + 3x

y = 6x - 3x

y = 3x (1)

y = $15 (2)

substituting the value of y from equation (2) into equation (1)

15 = 3x

x = 15/3 = 5

thus, cost of one comic book = $5

Answer:

5$.

Step-by-step explanation:

Let's denote the cost of one Sailor Moon comic book as x .

The cost of 6 Sailor Moon comic books is 6x.

According to the given information, the cost of a Nirvana vinyl plus 3 comic books is equal to the cost of 6 Sailor Moon comic books.

So, 15 + 3x = 6x , as the vinyl costs $15.

Now, let's solve for x :

Subtract 3x from both sides: 15 = 3x

Divide by 3: x = 5

Therefore, the cost of one Sailor Moon comic book is $5.

3) Solve this system of linear equations by elimination.y=x-1
2x-y=0

*x=-1,y=-2
*x=1,y=2
*x=2,y=1
*x=-2,y=-1

Answers

Answer:

Solving this system of linear equations by elimination we get x=-1 and y=-2

Option 1 is correct option.

Step-by-step explanation:

We are given equations:

$y=x-1---eq(1)\n2x-y=0---eq(2)$

We need to solve by Elimination method.

Elimination method: Add or subtract the equations to get an equation in one variable.

Rearranging the equation 1 we get

$-x+y=-1---eq(1)\n2x-y=0---eq(2)$

Add eq(1) and eq(2)

$-x+y=-1\n2x-y=0\n------\nx=-1$

So, after eliminating y we get x=-1

Now finding y by putting x in eq(1)

$y=x-1\ny=-1-1\ny=-2$

We get y=-2

So, solving this system of linear equations by elimination we get x=-1 and y=-2

Option 1 is correct option.

Jane Marko buys a car for $43,900.00. in three years, the car depreciates 48% in value. How much is the car worth in three years A.$21,950.00
B.$21,072.00
C.$22,828.00
D.$22,000.00

Answers

So we want to know what is the value of the car after three years if the car depricates in value for 48% and we know that the initial value of the car is 43900$. So if the price depricates for 48%, that means the new value is 52% of the initial value so: 43900$*0.52=22828$. So C is the correct answer.
