First you had to switch sides of equation.

2(i+w)=p

Then you divide by two from both sides of equation form.

\frac{2(i+w)}{2}= \frac{p}{2}

Simplify.

i+w=\frac{p}{2}

Next, subtract by i from both sides of equation form.

i+w-i=\frac{p}{2}-i

Finally, simplify by equation.

w=\frac{p}{2}-i

Final answer: \boxed{w=p/2-i}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

3(4x-10)=2(3x-30) i need help again i have to turn in all of my school work tomorrow so i don't fail the 8th grade
gayaneshka [121]

Answer:

The result for this equation is x = -5 .

Step-by-step explanation:

-Solve the equation:

3(4x-10)=2(3x-30)

-Use Distributive Property:

3(4x-10)=2(3x-30)

12x - 30=6x - 60

-Subtract 6x and from 12x :

12x - 30 -6x=6x -6x - 60

6x - 30=-60

-Add both sides by 30:

6x - 30 +30=-60 +30

6x =-30

-Then, you divide both sides by 6:

\frac{6x}{6}=\frac{-30}{6}

x = -5

So, therefore the answer is x = -5 .

Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used. He has another gift card for $145 that loses
sweet [91]

Answer:

Equation 1 = Equation 2

165 - 4x = 145 - 3.50x

Step-by-step explanation:

Let x represent the number of 30-day periods.

Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used.

Therefore the equation =

$165 -$4 × x

= 165 - 4x.......... Equation 1

He has another gift card for $145 that loses $3.50 for each 30-day period it is not used.

$145 -$3.50 × x

= 145 - 3.50x........... Equation 2

Hence, an equation for the number of 30-day periods until the value of the gift cards will be equal is obtained by equating Equation 1 and Equation 2 together

So, we have

Equation 1 = Equation 2

165 - 4x = 145 - 3.50x

We simplify further:

165 - 145 = -3.50 + 4.0x

20 = 0.5x

x = 20/0.5

x = 40

Therefore, number of each 30-day periods until the value of the gift cards will be equal is 40

Write a polynomial that represents the length of the rectangle<br><br> help please !!
disa [49]

Answer:

\textsf{Length}=0.8x^2-0.7x+0.7\quad \sf units

Step-by-step explanation:

Area of a rectangle = width × length

Therefore, to find the length of the rectangle, we need to divide the area by the width.

Using long division:

\large\begin{array}{r}0.8x^2-0.7x+0.7\phantom{)} \\x+0.5{\overline{\smash{\big)}\,0.8x^3-0.3x^2+0.35x+0.35\phantom{)}}}\\-~\phantom{(}\underline{(0.8x^3+0.4x^2)\phantom{-b))))))))))))))}}\\0-0.7x^2+0.35x+0.35\phantom{)}\\ \underline{-~\phantom{()}(-0.7x^2-0.35x)\phantom{-b)))))}}\\ 0.7x+0.35\phantom{)}\\\underline{-~\phantom{()}(0.7x-0.35)}\\ 0\phantom{)}\end{array}

Therefore, the <u>length</u> of the rectangle is:

0.8x^2-0.7x+0.7
