Answer:

Solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex]

We know that [tex]\sqrt{x} = x^{\frac{1}{2}}[/tex]

Solving:

[tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}\\=((\sqrt{21}-2\sqrt{7} )^2)^\frac{1}{2}[/tex]

We know that [tex](a^2)^\frac{1}{2}=a[/tex]

= [tex]\sqrt{21}-2\sqrt{7}[/tex]

So, solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]

Answer:

£16

Step-by-step explanation:

Step one:

given data

The price of a shirt is £64

When the price is reduced by 3/4, i.e 0.75

the reduced amount can be calculated as

0.75*64

=£48

Step two:

The new price or the cost of the shirt when the price is reduced is

= 64-48= £16

Answer:

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}=\sqrt{\left(5ab\right)^3}[/tex]

Step-by-step explanation:

Let us consider the expression

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}[/tex]

Writing the expression as a radical

But, let us revise some rules:

[tex]\sqrt{a}=a^{\frac{1}{2}}[/tex]

[tex]\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

[tex]\left(a\cdot \:b\right)^n=a^nb^n[/tex]

let us solve now

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}[/tex]

[tex]=5^{\frac{3}{2}}\left(ab\right)^{\frac{3}{2}}[/tex]         ∵  [tex]\:5^{\frac{3}{2}}=5\sqrt{5}[/tex]

[tex]=\left(5ab\right)^{\frac{3}{2}}[/tex]

[tex]=\left(5ab\right)^{3\cdot \frac{1}{2}}[/tex]

[tex]=\left(\left(5ab\right)^3\right)^{\frac{1}{2}}[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt{a}=a^{\frac{1}{2}}[/tex]

[tex]=\sqrt{\left(5ab\right)^3}[/tex]

Thus,

[tex]5\sqrt{5}\left(ab\right)^{\frac{3}{2}}=\sqrt{\left(5ab\right)^3}[/tex]

Answer:

x=3, y=13. (3, 13).

Step-by-step explanation:

7x-8=5x-2

7x-5x-8=-2

2x-8=-2

2x=-2+8

2x=6

x=6/2=3

y=5(3)-2=15-2=13

Answer:

given y=7x-8 i

y=5x-2 ii

Step-by-step explanation:

equating equation i and ii which is i=ii

7x-8=5x-2

7x-5x= -2+8

2x=6

x=6÷2

x=3

now

putting the value of xbin equation i

y=7x-8

y=7×3-8

y=21-8

y=13

hence the value of x and y is 3 and 13 respectively

Answer:

7 nickels

1 pennie

Step-by-step explanation:

Answer:

Connor has 7 nickles and 1 penny.

Step-by-step explanation:

7 * 5 = 35

5 is the value of a nickel.

1 * 1 = 1

35 + 1 = 36

Therefore, Connor has 7 nickels and 1 penny.

7 inches = 17.78 cm

Step-by-step explanation:

I looked it up

Answer:

17.78

Step-by-step explanation:

Each inch is 2.54cm.

We will first multiply 2.54 into 7 inches, since it is asking us for the centimeters, then our work should now look like this: 2.54 x 7 = 17.78

We can check our work by dividing the sum by the number in our equation.

17.78/7= 2.54

Answer:

x = 20

Step-by-step explanation:

Two lines are parallel. So, alternate interior angles are congruent.

x +8 + 6x - 58 = 90

7x - 50 = 90

        7x = 90 +50

       7x = 140

         x = 140/7

x = 20

Y la pregunta?

Answer:

x= -13/1,1

3x+5=8

-(3x+5)=8

x=1

x=-13/3

x=-13/3,1

Answer:

x and equal 1 or -13/3

Step-by-step explanation:

this is an absolute value equation so the equation can either equal 8 or -8. if you set up two equations that are 3x+5=8 and 3x+5 = -8 and just isolate the x, you get 1 and -13/3.

Answer:

-1

Answer:

Step-by-step explanation:

-6n + 2.9 = 11

subtract 2.9 from both sides

-6n = 8.1

divide both sides by -6

n = -1.35

2/3n - 3 = 8

add 3 to both sides

2/3n = 11

multiply both sides by 3

2n = 33

divide both sides by 2

n = 16.5

hope this helps <3

Answer:

left side:

-6n = 11 - 2.9

-6n = 8.1

n = - 8.1/6

n = - 1.35

right side:

2/3 n = 8 + 3

2/3 n = 11

n = 33/2

n = 16.5
