Answer and explanation:

Original cost of jeans =$64

Markdown by 50%= 0.50*64= $32

Additional discount by clearance sign 50% =0.50*32= $16

Therefore I disagree with Johnny. First the original price $64 was reduced by half of the price 50% of $64 =$32. Secondly the new price $32 is then also reduced by half of it 50% giving us $16. Therefore the discounts did not wipe off all the price as suggested by Johnny.

Answer:

x ≈ 11.6 m

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 10.7² = 15.8²

x² + 114.49 = 249.64 ( subtract 114.49 from both sides )

x² = 135.15 ( take square root of both sides )

x = [tex]\sqrt{135.15}[/tex] ≈ 11.6 m ( to the nearest tenth )

Answer:

6/11

Step-by-step explanation:

After taking 2 counters with no replacement, that only one of these is white. We will see that the probability is 6/11.

Given that;

there are 11 counters, 5 of them are white, 6 are not white

First we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:

p = 5/11

And, also notice that there are 2 permutations:

first white, then non-white.

first non-white, then white.

So we need to add a factor 2.

P = 2*p*q = 2*(5/11)*(6/10) = 6/11

The probability is 6/11

We can also Do:

11/11 = Whole

11 - 5 = 6

Hence, Answer = 6/11

Answer:

Solution: (1,-2)

Step-by-step explanation:

System of Equations

Given the equations:

[tex]-7x-8y=9\qquad\qquad [1][/tex]

[tex]-4x+9y=-22\qquad\qquad [2][/tex]

We'll solve it by elimination. It means eliminating one of the variables by equating their coefficients. We select the variable y. To eliminate it, multiply the equation [1] by 9 and the equation[2] by 8:

-63x-72y=81

-32x+72y=-176

Adding up both equations:

-95x=-95

Solving:

x=-95/(-95)=1

x=1

Now to eliminate x and find y, multiply [1] by 4 and [2] by -7:

-28x-32y=36

28x-63y=154

Adding up both equations:

-95y=190

Solving:

y=190 / (-95) = -2

y=-2

Solution: (1,-2)

Answer:

I think it is 4

You need a graph to do that

Answer:

The easiest way to solve this is by elimination.  

3x - y = 6  

6x + y = 21

Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:

9x = 27  

Then solving for x leaves you with x = 3  

Then you take the x value of three and plug it into to either of the equations, so  

3(3) - y = 6

9 - y = 6  

subtracting 9  

-y = -3  

then dividing by -1  

y = 3  

so the solution is x = 3 y = 3 or (3,3)  

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Add 3x + 6x, and execute the y, then -6 from 21 and you got ur answer of 15!

So, Henrietta is older

Answer:

The Answer is 1 over 7 times 7 times 7 times 7 times 7 times 7

Step-by-step explanation:

All you have to do is multiply the exponents.

[tex]7^{3*(-2)} =7^{-6}[/tex]

and the rule says :

[tex]x^{-a} = \frac{1}{x^{a} }[/tex]

So that means :

[tex]7^{-6} =\frac{1}{7^{6} } =\frac{1}{7*7*7*7*7*7}[/tex]

1 over 7 times 7 times 7 times 7 times 7 times 7  is equivalent to (73)−2.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here we have,

(7^3)(−2)

=7^(-6)

=1/7^6

=1/7*7*7*7*7*7

Hence, 1 over 7 times 7 times 7 times 7 times 7 times 7  is equivalent to (73)−2.

Answer:

k = -8

Step-by-step explanation:

-2k+13=-8k-35

Add 8k to each side

-2k+8k+13=-8k+8k-35

6k +13 = -35

Subtract 13 from each side

6k+13-13 = -35-13

6k = -48

Divide by 6

6k/6 = -48/6

k = -8

Answer:

its either counterclockwise or clockwise 90 degree rotation

Step-by-step explanation:

each point of the given figure has to be changed from (x, y) to (y, -x)

Answer:

Step-by-step explanation:

c.  y = (x^2 + 3)(x + 4)

y = x^3 + 4x^2 + 3x + 12

d. y = (x^2 + x) / √x

y =   (x^2 + x) /  x^1/2

y = x^2/ x^1/2  +  x / x^1/2

y = x^(2 - 1/2) + x(1 - 1/2)

y = x^3/2 + x^1/2

or x =  √(x^3) + √x

e.   y = 5 /x^2

y = 5x^(-2)
