Step-by-step explanation:

90 min per day

10 min before school

=> she can watch TV during (90-10) 80 minutes after school

if each episode = 20 minutes

she will be able to watch 80:20 soit 4 episodes after school

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)

Step-by-step explanation:

Original rectangle

L = 2*w

w = w

New rectangle

2w + 4

w - 3

Area New rectangle

(2w + 4)(w - 3) = 600               Remove the brackets

2w^2 - 6w + 4w - 12 = 600     Combine the left

2w^2 - 2w -  12 = 600             Subtract 600 from both sides

2w^2 - 2w - 600 - 12 = 0        Combine

2w^2 - 2w - 612 = 0                This factors.

(w- 18)(w + 17) = 0

w +  17 will produce nothing useful. What is - 17 m ? Can you measure it?

w = 18

check

Original Triangle

w = 18

L = 36

Derived Triangle

L = 36 + 4 = 40

w = 18 - 3 = 15

LW = 600

Answer:

4) Dmytro drank more juice

5) Henrietta is older

Step-by-step explanation:

4)

Dmytro drank 7/4 bottles which is 1.75 bottles

Jitka drank 1 1/2 bottles which is 1.5 bottles

So, Dmytro drank more juice

5)

Henrietta is 7 2/3 years old which is 7.66

Jagdeep is 65/12 years old which is 5.41

So, Henrietta is older

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:

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]

hope it helps ... have a good day

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.

Step-by-step explanation:

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)

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)

Answer:

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 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.
