Answer:

£21

Step-by-step explanation:

Cost of 18 drinks = £54

Cost of 1 drink

= Cost of 18 drinks/18

= £54/18

= £3

Cost of 7 drinks

= Cost of 1 drink × 7

= £3 × 7

= £21

Answer:

I think the LCM is 72 for 18 and 24

Hey, there! Based on the table from the picture, every hour increased is $6 increased for the cost of the rental.

First hour: $10

Second hour: $16

Third hour: $22

Fourth hour: $28

So, final answer is:

+1 hour=+$6.

Anyways, I hope this helps! Enjoy your day! Take care!

Answer:

8.33333333333

Step-by-step explanation:

Solution for 3x-7=18 equation:

3x - 7 = 18

3x = 18 + 7

3x = 25 (divide both sides by 3 to get x)

3x/3 = 25/3

x = 8.33333333333

Answer:

130 °

....................

Hi! I'm happy to help!

To solve this, we need to first solve for x.

The total of all the interior angles in a quadrilateral (closed, not curved, shape with 4 sides) is 360°. So, we can single out the xs by subtracting the other angles.

360-89

271

271-76

195

Now that we know that, without the other two angles, the quadrilateral is worth 195. The only 2 angles left have x in them. Since there are 3 xs, we can use this to find out our x.

3x=195

Now, divide both sides by 3.

x=65

Now that we have the value of x, the measure of 2x will just be double that.

65×2

130

The measure of 2x is 130°

Answer:

z = (1 + i)6 =³√2(cos π4+ isinπ4)´6= 8 µcos3π2+ isin3π2)¶= −8i. Hence |z| = 8 and ¯z = 8i. z = (1 + i)

I think I am not real sure

In polar form, we have

[tex]1+i = \sqrt2 e^{i\pi/4}[/tex]

Then by DeMoivre's theorem,

[tex](1+i)^6 = \left(\sqrt2\right)^6 e^{i\,6\pi/4} = 2^3 e^{i\,3\pi/2} = -8i[/tex]

Then

[tex]|z| = |-8i| = \boxed{8}[/tex]

and

[tex]\bar z = \overline{-8i} = \boxed{8i}[/tex]

$453.60 + $5400 = $5853.60

Answer:

1 thousand

Step-by-step explanation:

1 ten = 10 x 1 one (Read, as “1 ten is 10 times as much as 1 one.”) 1 hundred = 10 x 1 ten (Say, “1 hundred is 10 times as much as 1 ten.”) 1 thousand = 10 x 1 hundred (Say, “1 thousand is 10 times as much as 1 hundred.”)i hope im right

Hi ;-)

12x = 36

x = 36 : 12

x = 3

Hey there! I'm happy to help!

We see that an unknown number x multiplied by 12 is equal to 36. How do we find this number? Well, you can simply go backwards and divide 36 by 12, and this will give us our answer.

36÷12=3

Another way you can think about this is dividing both sides of the equation by 12, which isolates our x.

12x=36

12x÷12=36÷12

x=3

Have a wonderful day and keep on learning! :D

Answer:

1. -4/7

2. 4/3

3. x^2 + 16x + 63

4. x^2 + 19x + 90

Step-by-step explanation:

1. (1, 8) and (8, 4)

slope = m = (8 - 4)/(1 - 8) = -4/7

2. (2, 4) and (5, 8)

slope = m = (8 - 4)/(5 - 2) = 4/3

3. (x + 9)(x + 7) =

= x^2 + 7x + 9x + 63

= x^2 + 16x + 63

4. (x + 10)(x + 9) =

= x^2 + 9x + 10x + 90

= x^2 + 19x + 90

12: Equal, because the cardinal number of {x,y,z} are same as {a,b,c}, that is, 3.

13: Not equal, because in set {0}, there is one element , while in set { } , there are no elements at all .

Hope it helps you. Have a nice day!

Answer:

68,162 is the answer

Step-by-step explanation:

54394+ 13768 = 68162

Answer: 0.166

Step-by-step explanation:

Converting to a decimal:

1/6 = 0.1666 (1 divided by 6 - long division)

Rounding:

0.1666 to the nearest thousandth = 0.166
