Answer:

11-9=2 then, 2^3=8 , finally 8X2=16

Step-by-step explanation:

remember order of operations

Answer:

12 km

Step-by-step explanation:

--------------------------------

time out + time back = total time

d/5 + d/4 = 5.4

multiply both sides by 20 to clear the fractions

4d + 5d = 108

9d = 108

Divide both sides by 9

d = 12 km

Answer:5

Step-by-step explanation:

Answer:

82° because

98° + 70° = 168°

360° - 168° = 192°

192° is for two angles, so it can't be 192°, 220°

it's not VERY obtuse angle. So it remains only 82°

Answer:

  see below

Step-by-step explanation:

Perhaps you're stuck because it is too simple. If any value in the x-column is repeated, the relation is not a function.

Of the two relations shown, the first is not a function (x=3 is repeated), and the second one is a function (all the x-values are different).

Answer:

D

Step-by-step explanation:

speed = space/time

24/4.3 = 5.6 ft/s

Answer:Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer: 8

Step-by-step explanation

Answer:

$8

Step-by-step explanation:

If we just keep track of the money in the account, we can solve this pretty quickly. If the balance is -20, and we subtract another 10 from it, it gives us -30. $38 is then deposited into the account, giving us a balance of $8.

Answer:

x=10

Step-by-step explanation:

Let the number = x

∴ 2x/5=4

∴2x=5*4

∴2x=20

∴x=20/2

∴x=10

Hope it helps you!

Answer:

2x / 5 = 4

x = 10

Step-by-step explanation:

Twice a number   divided by 5   gives 4

          2x                     / 5                  = 4

2x / 5 = 4

Multiply both sides by 5

2x = 20

Divide both sides by 2

x = 10

Answer:

Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.

Step-by-step explanation:

Dado que la abuela de Jorge, cuando llegan las fechas navideñas, reparte 120€ entre los tres nietos de la siguiente forma: Jorge, como es el mayor, recibe 10 € más que su prima Alejandra, y esta 10 € más que la prima pequeña Marina, para determinar cuánto dinero recibe cada uno se debe realizar el siguiente cálculo:

J = A + 10

A = M + 10

M = M

J + A + M = 120

A + 10 + M + 10 + M = 120

M + 10 + 10 + M + 10 + M = 120

3M + 30 = 120

3M = 120 - 30

M = 90 / 3

M = 30

Por lo tanto, Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.

Answer:

the value of x = 3 and y = 3

Step-by-step explanation:

2x + y = 9 ------------ (1)

-2y -2x = -22 ------------ (2)

Subtract (1) from (2)

-2x -2y = -22

2x + y = 19

----------------------

       -y = -3

        y = 3

Put the value of y in equation 1

2x + y = 9

2x + 3 = 9

2x = 9 - 3

2x = 6

x = 6/2

x = 3

Therefore, the value of x = 3 and y = 3

Answer:

y = 8/27

Step-by-step explanation:

given

x = 7

y = 4x*y - 4(2)

y = 4*7*y - 8

y = 28y - 8

8 = 28y - y

8 = 27y

8/27 = y

to prove

y = 4x*y - 4(2)

8/27 = 4*7*y - 8

8/27 = 28*8/27 - 8

8/27 = 224/27 - 8

8/27 = 224 - 27*8/27

8/27 = 8/27

hence it is proved that y is 8/27 .

Answer:

r = -6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept.

Slope 3/4

This means that [tex]m = \frac{3}{4}[/tex], and thus:

[tex]y = \frac{3}{4}x + b[/tex]

(6,3)

This means that when [tex]x = 6, y = 3[/tex]. We use this to find b. So

[tex]y = \frac{3}{4}x + b[/tex]

[tex]3 = \frac{3}{4}(6) + b[/tex]

[tex]b = 3 - \frac{18}{4} = \frac{12}{4} - \frac{18}{4} = -\frac{6}{4}[/tex]

So

[tex]y = \frac{3}{4}x - \frac{6}{4} = \frac{3x - 6}{4}[/tex]

(-6, r)

r is y when [tex]x = -6[/tex]. So

[tex]y = \frac{3(-6) - 6}{4} = -6[/tex]

So r = -6.

Answer: 11.20

Step-by-step explanation:

Divide. 56.00 ÷ 5 = 11.20 therefore each shirt cost 11.20 Hope that helps!

Answer:

Divide.

Answer : option B

Step-by-step explanation:

Cost             Number of shirts

 56                      5

  x                        1

 [tex]\frac{56}{x} = \frac{5}{1}[/tex]

[tex]5 \times x = 56 \times 1\\\\x = \frac{56}{5} = 11.20[/tex]

Answer:

1 1/6

Step-by-step explanation:

the problem is asking you to do 1/6 7 times. Lets break it down and make it 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6 plus 1/6

so lets add the all the numerators 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 is 7

the numerator value is 7 and you dont add the denominator so it stays as 6

so the answer is 7/6 or 1 1/6 as a mixed number

Answer:1 1/6

Step-by-step explanation: The answer is one and one sixth because when you imagine that the 7 is over one, when you times it you get 7/6 and that is 1/ 1/6

Answer:

x = -9 ; x = 7

Step-by-step explanation:

We have to find two numbers whose product is -63 and whose sum is 2

the two numbers are 9 and -7

(x+9)(x-7) = 0

x = -9

x = 7

Answer:

First the mode.  Since 5 popped up the most, 5 is the mode.

Next is the median.  I crossed 1 dot from each side until it shows the last dot, and 5 was the last one.

After that the range.  9-2=7

Finally the worst, the mean... 2+2+3+3+3+4+5+5+5+5+5+6+6+6+8+9+9+9+9

=104/19=5.47

SO, Mode=5 Median=5 Range=7, and the mean is 5.47 (rounded nearest hundred)

Answer:

The coefficient of variation after the tax is imposed is 0.033

Step-by-step explanation:

Given

[tex]\mu =1000[/tex] --- mean

[tex]\sigma^2 = 1200[/tex] --- variance

[tex]tax = 10\%[/tex]

Required

The coefficient of variation

The coefficient of variation is calculated using:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

After the tax, the new mean is:

[tex]\mu_{new} = \mu * (1 + tax)[/tex]

[tex]\mu_{new} = 1000 * (1 + 10\%)[/tex]

[tex]\mu_{new} = 1100[/tex]

And the new variance is:

[tex]\sigma^2_{new} = \sigma^2 * (1 + tax)[/tex]

[tex]\sigma^2_{new} = 1200 * (1 + 10\%)[/tex]

[tex]\sigma^2_{new} = 1320[/tex]

So, we have:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

[tex]CV = \frac{\sqrt{1320}}{1100}[/tex]

[tex]CV = \frac{36.33}{1100}[/tex]

[tex]CV = 0.033[/tex]
