I need help on this problem expand 2-x(x+6)

(This is distributive property)

Answer:

x = 4

y = 36

Step-by-step explanation:

use substitution

y=3x+24

y=9x

therefore . 9x=3x+24

x = 4

sub 4 in for x and solve for y

y = 9(4) = 36

Answer:

3 people

Step-by-step explanation:

Let "x" represent the number of people who payed with cash

Let "y" represent the number of people who payed with credit card

14x +15y = 177 ---------1

3x =y--------- 2

solving simultaneously,

put eqn 2 into eqn 1

14x + 15 (3x) = 177

14x + 45x = 177

59x = 177

x=3

From eqn 2 , y = 3 x

y = 3 (3)

y=9

therefore the number of people who paid with cash were 3.

Answer:

They got $91 in total

Step-by-step explanation:

I did some trial and error and when I reached 65 dollars for Gavin I realized that Jim would be $29. So 65 - 29 = $39. Btw substitute $ for £

Answer: £91

Step-by-step explanation:

Let x be the amount of money Jim gets

Let x + 39 be the amount of money Gavin gets

Given information

Ratio = 5 : 2 (Gavin to Jim)

Jim = x

Gavin = x + 39

Set up proportion

5 / 2 = (x + 39) / x

Cross multiply to reduce fraction form

5x = 2 (x + 39)

Expand parentheses and apply the distributive property

5x = 2 · x + 2 · 39

5x = 2x + 78

Subtract 2x on both sides

5x - 2x = 2x + 78 - 2x

3x = 78

Divide 3 on both sides

3x / 3 = 78 / 3

x = 26

Find the amount of money they get altogether

Gavin + Jim

=x + 39 + x

=(26) + 39 + (26)

=65 + 26

Answer:

Option D. x²+y-2

Step-by-step explanation:

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Answer:

The correct option is choice D.  x^2+y−2

Algebraic expression means that equation needs to have one variable, meaning any alphabet and one kind of operation. Operations are + - / and*

If you look at your answer choices, option d is the only that has an expression as well as the operation, so both things in one equation.

Answer:

the length of each shape will alternate between even numbers and is numbers.

Step-by-step explanation:

just think !

there are 3 cubes in the basic shape.

now, with every step he adds 1 more cube to the length, and one more cube to the height. that means 2 more cubes.

so, it goes 3, 5, 7, 9, ... cubes

therefore, the first answer is wrong. the shape in every step will always have an uneven (odd) number of boxes. remember, adding an even number to an uneven number will always result in an uneven number. only uneven and uneven or even and even can have even results.

but the length itself - he only adds there one box at a time, will go

2, 3, 4, 5, 6, ...

so, it will alternate between even and uneven numbers.

Answer:

slope=2/2 or 1

Step-by-step explanation:

From (-2,0) rise up by 2 and then run to the right and land on 2. So the slope will be 2/2. To simplify it's 1.

Remember this Rise goes⬆/Run to the right➡ or the other way around depends on how the graph is but you get my drift, right? ☺

Answer:

300 dimes in total

Step-by-step explanation:

He has 6 rows with 50 in each. 6 times 50 = 300 dimes

Answer:

300

Step-by-step explanation:

1 roll = 50 dimes

6 roll = x                       Cross multiply

1*x = 50 * 6

x = 300 dimes

He has 300 dimes altogether.

Answer:

Answer:

[tex]A = \frac{1}{2} \pi r [/tex]

multiply all sides by 2:

[tex]2 \times A = ( \frac{1}{2} \pi r) \times 2 \\ \\ 2A = \pi r[/tex]

divide all sides by r:

[tex] \frac{2A}{r} = \frac{\pi r}{r} \\ \\ \frac{2A}{r} = \pi[/tex]

therefore:

The xy-plane has a normal vector of 〈0, 0, 1〉, and any plane parallel to it will have the same normal vector.

Then the equation of the plane through (6, 3, 2) that is parallel to the xy-plane has equation

〈x - 6, y - 3, z - 2〉 • 〈0, 0, 1〉 = 0

==>   z - 2 = 0

==>   z = 2

Step-by-step explanation:

Height from the ground=16ft

distance from wall= 12ft

length of the stick=?

According to the Pythagoras theorem the square of the hypotenuse is equal to the sum of the squares of the opposite sides.

Here the stick is the hypotenuse.

[tex]12^{2} +16^{2} = x^{2}[/tex]

144+ 256= [tex]x^{2}[/tex]

[tex]x^{2}[/tex]= 400

[tex]x=\sqrt{400} \\x= 20[/tex]

Hence the length of the stick is 20ft.

Explanation on how to place the decimal places I found on a good website:

Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product.

To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.

Multiply 0.7 by 0.352

   0.7      1 decimal place

0.352      3 decimal places

              A total of 4 decimal places

Once you have found the sum of the decimal places in each factor, you know how many decimal places the product will need after its decimal point. Starting at the far right of the number, move the decimal point toward the left that number of decimal places.

0.2464 (4 decimal places after the decimal point)

Dividing decimals

1.  Move the decimal point in the divisor to the right to make the divisor a whole number.  

2.  Move the decimal point in the dividend the same number of places to the right.  

3.  Place the decimal point in the quotient directly over the decimal point in the dividend for the final quotient.

4.  Divide as if working with whole numbers
