Answer:

b = 0

Step-by-step explanation:

The modulus of a + bi is

| a + bi | = [tex]\sqrt{a^2+b^2}[/tex] , then

[tex]\sqrt{a^2+b^2}[/tex] = a ( square both sides )

a² + b² = a² ( subtract a² from both sides )

b² = 0 ⇒ b = 0

Hello :D

Let's form an equation:

x/5 = 27

Let's form another equation:

(x+y)/7 = 34

Rearrange equation one so it is x = 27 x 5 = 135

Now we can substitute this value into equation 2:

(135 + y)/7 = 34

135 + y = 238

y = 238 - 135

y = 103

Answer is 103

Answer:

103 christmas trees.

Step-by-step explanation:

total trees sold in the first five days:

[tex]27 \times 5 = 135[/tex]

total trees sold in this week:

[tex]34 \times 7 = 238[/tex]

The answer is:

[tex]238 - 135 = 103[/tex]

Answer:

x = 11

Step-by-step explanation:

[tex] \frac{x + 2}{6} - \bigg( \frac{11 -x }{3} - \frac{1}{4} \bigg) = \frac{3x - 4}{12} \\ \\ \frac{2(x + 2)}{2 \times 6} - \bigg( \frac{4(11 - x) - 1 \times 3}{3 \times 4} \bigg) = \frac{3x - 4}{12} \\ \\ \frac{2x + 4}{12} - \bigg( \frac{4 4 - 4x- 3}{12} \bigg) = \frac{3x - 4}{12} \\ \\ \frac{2x + 4}{12} - \bigg( \frac{41 - 4x}{12} \bigg) = \frac{3x - 4}{12} \\ \\ \frac{2x + 4 - 41 + 4x}{ \cancel{12}} = \frac{3x - 4}{ \cancel{12}} \\ \\ 6x - 37 = 3x - 4 \\ \\ 6x - 3x = 37 - 4 \\ \\ 3x = 33 \\ \\ x = \frac{33}{3} \\ \\ \huge \red{ \boxed{ x = 11}}[/tex]

Answer:

Answer is D

C = (4 x 16) - 6

Step-by-step explanation:

There is 4 packages. Packages can hold many cookies in this case 16 cookies can be placed inside 1 package.

The total number of cookies can be calculated:

16 x 4 (4 packages altogether with 16 cookies in each package)

They did not eat 6 cookies so 6 cookies are leftover or remaining:

(16 x 4) - 6 (subtract 6 because they did not eat it, we want what they already ate - takeaway 6)

Basically means: The Total minus The Remaining

(The Total - The Remaining)

Answer:

Answer:

The answer is -12

Step-by-step explanation:

2xy + 3x + 4x + 3 if x = 5 and y = -5

Now,

2xy + 3x + 4x + 3

2(5)(-5) + 3(5) + 4(5) + 3

-50 + 15 + 20 + 3

38 - 50 = -12

Thus, The answer is -12

Answer:

The answer to that is a. 7/20

The product of [tex]\frac{7}{10} \times \frac{3}{6}[/tex] will be 7/20.

Hence option A is correct.

Multiplication : It is one of the operator in mathematics among addition , subtraction and division.

Given, that product of 7/10 × 3/6

Multiplication of fractional terms:

[tex]\frac{a}{b} \times \frac{c}{d}[/tex] [tex]= a\times c/b\times d[/tex]

Apply multiplication of fractional terms

[tex]\frac{7}{10} \times \frac{3}{6} = 7\times 3 / 10 \times 6\\\\= \frac{21}{60}\\ \\= \frac{7}{20}[/tex]

Therefore product of multiplication is 7/20.

Thus correct answer is option A.

You have three cases, if x is strictly greater than 3 (which is our case since x = 6), the value of the function is √(x+3).

so f(6) = √(6+3) = √9 = √(3*3) = √(3²) = 3

Answer:

The coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]

Step-by-step explanation:

The Coordinates of point A are (-4,-7), and the coordinates of point B are (9,4).

Let us assume that the coordinates of point [tex]\dfrac{3}{10}[/tex] of the way from A to B are P(x,y).

Now,

Applying the section formula,

[tex]x=\dfrac{3 \times 9+7 \times -4}{3+7}\\x=\dfrac{27 -28}{10}\\x=\dfrac{-1}{10}[/tex]

[tex]y=\dfrac{3 \times 4+7 \times -7}{3+7}\\y=\dfrac{12 -49}{10}\\y=\dfrac{-37}{10}[/tex]

Therefore, the coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]

Step-by-step explanation:

I took 1 5/8 feet and added it to both...

The new dimensions of the garden will be 18 3/8 feet and 14 1/8 feet.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The dimensions of a rectangular garden are 12 1/2 feet by 16 3/4 feet. If 1 5/8 feet is added to all the sides.

Then the length will be

L = 16  3/4 + 1  5/8

L = 17  (3/4 + 5/8)

L = 17  11/8

L = 18  3/8 feet

Then the width will be

W = 12  1/2 + 1  5/8

W = 13  (1/2 + 5/8)

W = 13  9/8

W = 14  1/8 feet

The new dimensions of the garden will be 18 3/8 feet and 14 1/8 feet.

Answer:

Loss Amount: 175; Price: 3325

Step-by-step explanation:

You can multiply 3500 by 0.05 (which is 5% in decimal) to find how much is the loss. Then, you subtract the loss from the base price to find the new price.

Answer:

Loss =175, sold = 3325

Step-by-step explanation:

He bough at 3500

So 100 percent is 3500

And they said he had a 5% loss

So in other words, he sold it to Alex at 95% of the price he bought

So

3500 x 95%

3500 x 95/100

=3325

This is the price when Hitler sold it to alex

Now how much did Hitler lose?

3500 - 3325

=175
