Answer:

a 23 607

Step-by-step explanation:

Answer:

x = 3; y = -6

Step-by-step explanation:

 x - 2y =  15

2x + 4y = -18​

Multiply both sides of the first equation by 2. Write the second equation below it, and add the two equations.

     2x - 4y = 30

(+)  2x + 4y = -18

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

     4x         = 12

4x/4 = 12/4

x = 3

Now we substitute 3 for x in the first equation and solve for y.

x - 2y = 15

3 - 2y = 15

-2y = 12

y = -6

Answer: x = 3; y = -6

Answer:

I think it would be a rhombus.

Step-by-step explanation:

6.)

|x - 6| = 5

x + 6 = 5

x = 5 - 6

x = - 1

7.)

|3x - 7| = 12

3x + 7 = 12

3x = 12 - 7

3x = 5

x = 5/3

8.)

|2x + 9| - 10 = 5

2x + 9 - 10 = 5

2x - 1 = 5

2x = 1 + 5

2x = 6

x = 6/2

x = 3

Answer: A = {..., -1, 0, 1, 2, 3, 4, 5}

Step-by-step explanation:

We have that the set A is the set of all the integers equal to or smaller than 5.

To write in the Roster Method, we must list all the elements of this set, but we know that this set extends to minus infinity, then we should start with an ellipsis:

A = {...

Which means that it continues in that direction.

Then we can implicitly write the end of our set, and also some of the points so we can know the relation between the points in the set.

A = {..., -1, 0, 1, 2, 3, 4, 5}

And that is the set A in written with the Roster Method

Answer:

Base: [tex]7[/tex]

Exponent: [tex]4[/tex]

Step-by-step explanation:

What is the base and the exponent of [tex]7^4[/tex]?

If you want to know the base, you will have to look at the whole number. The whole number is 7. So that means the base is 7. The number on top of the whole number(exponent) is gonna be the exponent. The number 4 is on the exponent. So in that case, the number 4 is the exponent. So the base is 7 and the exponent is 4.

Hope this helps!

Answer:

Base(7)

Exponent(4)

Step-by-step explanation:

A base is always the whole number. In this exponent, the whole number you see is 7. So that means 7 is the base number. The exponent is the small number you see on top of the whole number(base). The exponent on top of the whole number is 4. So the base number is 7 and the exponent is 4.

Answer: 237.5 square inches

Step-by-step explanation:

Total surface area  of rectangular prism  = 2 (lw+wh +hl)

, where l= length

w = width

h= height

Given:  A rectangular prism and its dimensions are.

6.5 in.  ,5 in.  ,7.5 in.

Then, the total surface area of this prism  = 2 (6.5×5 + 6.5 × 7.5 + 5×7.5)

= 2 (32.5+ 48.75 + 37.5)

= 2 (118.75)

= 237.5

Hence, the total surface area of this prism = 237.5 square inches

Answer:

30

Step-by-step explanation:

=9 + 5 x 10 + 1 + -15 x 2 = ( 5 x 10 ) + ( −15 x 2) + ( 9 +1  ) = 5 x 10 + −15 x 2 + 10

Answer:

30

Step-by-step explanation:

9+(5x10)+1-(15x2)

First, we must evaluate the numbers in the parentheses. (5x10) is 50, and (15x2) is 30. Since we have the answers to that, we can now put the expression as: 9 + (50) + 1 - (30).

9 + (50) = 59

59 + 1 = 60

60 - (30) = 30

Therefore, the answer is 30.

Answer

13/4

Step-by-step explanation:

Answer:

Step-by-step explanation:

A

Answer:

Step-by-step explanation:

width = w

length = 12 + w

Perimeter of rectangle = 2*length + 2*width since perimeter measures the distance around an object.

The perimeter of a certain rectangle is 16 times the width means 2 * (12 + w) + 2 *w = 16w

24 + 2w + 2w = 16w

24 + 4w = 16w  subtract 4w from both sides

24 = 12 w  divide both sides by 12

2 = w

width = 2 cm

length = 12 + 2 = 14 cm

Answer:

[tex]Width = x + 4[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Area = x^2 + 11x + 28[/tex]

[tex]Length = x + 7[/tex]

Required

Determine the width

For a rectangle:

[tex]Area = Length * Width[/tex]

Substitute values for Length and Area

[tex]x^2 + 11x + 28 = (x + 7) * Width[/tex]

Factorize the expression on the left hand side

[tex]x^2 + 7x + 4x + 28 = (x + 7) * Width[/tex]

[tex]x(x + 7) + 4(x + 7) = (x + 7) * Width[/tex]

[tex](x + 7)(x + 4) = (x + 7) * Width[/tex]

Divide both sides by x + 7

[tex]Width = x + 4[/tex]

Answer:

6.72 Hours

Step-by-step explanation:

Since the new phone can last 60% Longer than 4.2 hours, we multiply 4.2 by .6 and then add it back to 4.2

4.2 X 60% = 2.52

2.52+4.2=6.72

Therefore, the new phone can last 6.72 hours

Answer:

42 / [15 - (3 + 5)]

42 / [15 - 8]

42 / 7

Answer: 6

Answer:

Step-by-step explanation:

7x - 8y = -12

-16x + 8y = 12

-9x = 0

x = 0

-4(0) + 2y = 3

2y = 3

y = 3/2

(0, 3/2)

Answer:

-1/2 = x

Step-by-step explanation:

2 (x - 4) = 6x - 6 (distribute)

2x - 8 = 6x - 6 ( subtract 2x from each side)

- 8 = 4x - 6 ( add 6 to both sides)

-2 = 4x ( divide each side by 4)

x = -2/4 which simplifies to -1/2

Answer:

x is -1/2   (negative one half)

Step-by-step explanation:

Apply distributive property on the left in order to get rid of the parenthesis, and then group all terms in x on the right, and all numerical terms on the left. Combine like terms, and finally solve for "x":

2 (x - 4) = 6 x - 6

2 x - 8 = 6 x - 6

6 - 8 = 6 x - 2 x

-2 = 4 x

x = -2/4

x = -1/2

FOR A SQUARE,

Properties A, C and D apply

FOR A RHOMBUS,

Properties C and D apply

Answer:

Option 1 F

Step-by-step explanation:

If all the terms in an equation have a common factor, then you can divide all the terms by that common factor and receive the same answer. In this question, all the terms are divisible by 3 (3, 12 and 6 can all divide by 3) so we can divide them all by 3 while keeping the equation equal, which gives us:

3y/3 = 12x/3 -6/3

y = 4x - 2

Answers:

36 individual black socks

38 individual white socks

Check: 36+38 = 74 total individual socks

====================================================

Work Shown:

b = number of pairs of black socks

w = number of pairs of white socks

w = b+1 since he has 1 more pair of white socks compared to black socks

2b = number of individual black socks

2w = number of individual white socks

2b+2w = total number of individual socks

2b+2w = 74

2b+2(b+1) = 74 .... plug in w = b+1

2b+2b+2 = 74 ... distribute

4b+2 = 74

4b = 74-2 .... subtracting 2 from both sides

4b = 72

b = 72/4 ... dividing both sides by 4

b = 18 is the number of pairs of black socks he has

2b = 2*18 = 36 is the number of individual black socks he has

w = b+1 = 18+1 = 19 is the number of pairs of white socks he has

2w = 2*19 = 38 is the number of individual white socks he has

2b+2w = 36+38 = 74 individual socks overall

Answer:

p (13 - 4 p)

Step-by-step explanation:

Simplify the following:

2 p (p + 2) - 3 p (2 p - 3)

Hint: | Pull a common factor out of 2 p (p + 2) - 3 p (2 p - 3).

Factor p out of 2 p (p + 2) - 3 p (2 p - 3), resulting in p (2 (p + 2) - 3 (2 p - 3)):

p (2 (p + 2) - 3 (2 p - 3))

Hint: | Distribute 2 over p + 2.

2 (p + 2) = 2 p + 4:

p (2 p + 4 - 3 (2 p - 3))

Hint: | Distribute -3 over 2 p - 3.

-3 (2 p - 3) = 9 - 6 p:

p (2 p + 9 - 6 p + 4)

Hint: | Group like terms in 2 p - 6 p + 4 + 9.

Grouping like terms, 2 p - 6 p + 4 + 9 = (4 + 9) + (2 p - 6 p):

p (4 + 9) + (2 p - 6 p)

Hint: | Combine like terms in 2 p - 6 p.

2 p - 6 p = -4 p:

p (-4 p + (4 + 9))

Hint: | Evaluate 4 + 9.

4 + 9 = 13:

Answer: p (13 - 4 p)

Answer:

g(-1) = 6

g(0) = 5

g(1) = 6

g(2) = 9

Step-by-step explanation:

Step 1: Plug in -1 for x

g(-1) = (-1)² + 5

g(-1) = 1 + 5

g(-1) = 6

Step 2: Plug in 0 for x

g(0) = 0² + 5

g(0) = 0 + 5

g(0) = 5

Step 3: Plug in 1 for x

g(1) = 1² + 5

g(1) = 1 + 5

g(1) = 6

Step 4: Plug in 2 for x

g(2) = 2² + 5

g(2) = 4 + 5

g(2) = 9
