Answer:

|8|

Step-by-step explanation:

Let the integer = x

x = - 2x - 24

x + 2x = - 24

3x = - 24

x = - 24/3

x = - 8

Hence, the integer is - 8

The number could be the positive of negative of 8

Hence, it is better expressed as |8|

IrinaVladis [17]

To start, first distribute 8 to (y+11) which would look something like this:
9y=8y+88
Now, subtract 8y from both sides in order to solve for and isolate the y value. This would result in your answer, y=88.

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2 1 inches. She p

Sauron [17]

The expression used for the length of ribbon that she needs for both pillows will be $4(2x^{2} +4x-6)$ .

The total length of the pillow she needs will be 130 inches.

Given,

The side length of pillow is $(2x^2 + 1) \ inches$ .

The side length of another pillow is $4x-7 \ inches$ .

We know that perimeter of square will be,

$P=4\times length$

So the perimeter of pillow will be,

$P=4\times (2x^2+1)\\$

$P=8x^{2} +4$

Similarly, the perimeter of another pillow will be,

$P=4\times (4x-7)$ ]

$P=16x-28$

Hence,the total length of ribbon that she needs for both the pillows will be,

$8x^{2} +4+16x-28\\8x^{2} +16x-24\\4(2x^{2} +4x-6)$

If $x=3.5\\$ then the total length of ribbon will be,

$4(2\times 3.5^{2}+4\times 3.5-6)\\4(2\times 12.25+14-6)\\$

$4(24.5+8)$

$4\times 32.5\\$

$130 \ inches$ .

Thus the required expression will be $4(2x^{2} +4x-6)$ and the total length of ribbon she needs will be 130 inches.

So, the correct option will be (D).

1 and 3/4 times 1 and 1/3

Orlov [11]

Answer:

7/3

Step-by-step explanation:

Simplify the following:

(1 + 3/4) (1 + 1/3)

Hint: | Put the fractions in 1 + 1/3 over a common denominator.

Put 1 + 1/3 over the common denominator 3. 1 + 1/3 = 3/3 + 1/3:

(1 + 3/4) 3/3 + 1/3

Hint: | Add the fractions over a common denominator to a single fraction.

3/3 + 1/3 = (3 + 1)/3:

(1 + 3/4) (3 + 1)/3

Hint: | Evaluate 3 + 1.

3 + 1 = 4:

(1 + 3/4)×4/3

Hint: | Put the fractions in 1 + 3/4 over a common denominator.

Put 1 + 3/4 over the common denominator 4. 1 + 3/4 = 4/4 + 3/4:

4/3 4/4 + 3/4

Hint: | Add the fractions over a common denominator to a single fraction.

4/4 + 3/4 = (4 + 3)/4:

4/3 (4 + 3)/4

Hint: | Evaluate 4 + 3.

4 + 3 = 7:

7/4×4/3

Hint: | Express 7/4×4/3 as a single fraction.

7/4×4/3 = (7×4)/(4×3):

(7×4)/(4×3)

Hint: | Cancel common terms in the numerator and denominator of (7×4)/(4×3).

(7×4)/(4×3) = 4/4×7/3 = 7/3:
