Answer:

Step-by-step explanation:

If you simplify the equations and the left side is identical to the right side, then there are an infinite number of solutions: the equation is true for all values of x.

Another way to simplify the equation is to subtract the right side from both sides. If that simplifies to 0 = 0, then there are an infinite number of solutions.

2x -6 -6x = 2 -4x . . . . eliminate parentheses

-4x -6 = -4x +2 . . . . no solutions (no value of x makes this true)

x +2 = 15x +10 +2x . . . . eliminate parentheses

x +2 = 17x +10 . . . . one solution (x=-1/2)

4 +6x = 6x +4 . . . . eliminate parentheses

6x +4 = 6x +4 . . . . infinite solutions

6x +24 = 2x -4 . . . . eliminate parentheses; one solution (x=-7)

The length of a rectangle is (5x − 1) cm and the width is (11 − 2x) cm. If the perimeter of the rectangle is 44 centimeters, wha

daser333 [38]

Answer:

57 cm²

Step-by-step explanation

<em>l = length</em>

<em>w = width</em>

<em>p = perimeter</em>

<em />

<em>(5x - 1) = length</em>

<em>(11 - 2x) = width</em>

<em>44 = perimeter</em>

<em />

<em>Formula for the perimeter of a rectangle:</em>

<em />

<em>Substitute the variables for the length and width with the values given to you by the problem, then solve.</em>

<em>(10x - 2) + (22 - 4x) = 44 (Distributive property)</em>

6x + 20 = 44

6x = 24

x = 4

<em>Plug x = 4 back into the length and width.</em>

Length = (5x - 1), (5(4) - 1), (19)

Width = (11 - 2x), (11 - 2(4)), (3)

<em>Area for a rectangle: Length × Width = Area.</em>

<em>This is all in cm so answer with cm²</em>

How many 1/2 cup servings are in the 7/8 cups of peanut butter

Sunny_sXe [5.5K]

This is more or less how you write the question.
$\frac{ \frac{7}{8} } { \frac{1}{2} }$

To solve it invert the 1/2 and multiply.
$\frac{7 * 2}{8 * 1}$

Which gives you 14 /8 whis is 1 3/4 cups.

Ok i have a few questions please give examples and descriptions as well

Arte-miy333 [17]

Answer:

1) Multiplying powers with the same base would be product rule. It where you just add the exponents. Dividing powers with the same base would be the quotient rule. Its where you subtract the exponents.

2)Where you multiply the two exponents together

3)The negative law is where for example, if it were in the numerator, then it would be placed at the denominator with a positive exponent whereas if it were in the denominator it would be on the numerator with the positive exponent. The zero law just states the anything to the power to zero is one.

Step-by-step explanation:

1) 3^3 x 3^4 = 3 ^3+4 = 3^7

3^9 ÷3² = 3^9-2 = 3^7

2) (3^2)^2 = 3^2×2 =3^4

3) 1/3^-5 = 3^5 \

3^-7 =1/3^7

2^0 = 1
