Answer:

$1652w-1652$ is equivalent to $\left(2w-2\right)\left(826\right)$

In other words:

$\left(2w-2\right)\left(826\right)=\:1652w-1652$

Step-by-step explanation:

Considering the expression

$\left(2w-2\right)\left(826\right)$

solving

$\left(2w-2\right)\left(826\right)$

$=\left(826\right)\left(2w-2\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac$

$a=\left(826\right),\:b=2w,\:c=2$

$=\left(826\right)\cdot \:2w-\left(826\right)\cdot \:2$

$=826\cdot \:2w-826\cdot \:2$

$=1652w-1652$

Therefore,

$1652w-1652$ is equivalent to $\left(2w-2\right)\left(826\right)$

In other words:

$\left(2w-2\right)\left(826\right)=\:1652w-1652$

What is the answer<br>2x+3x-7=42

Studentka2010 [4]

Answer:

x = $\frac{49}{5}$ or $9.8$

Step-by-step explanation:

First, combine like terms. Like terms are terms with the same amount of the same variable.

(2x + 3x) - 7 = 42

5x - 7 = 42

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

First, add 7 to both sides of the equation:

5x - 7 (+ 7) = 42 (+ 7)

5x = 42 + 7

5x = 49

Next, divide 5 from both sides of the equation:

(5x)/5 = (49)/5

x = 49/5

x = 9.8
