The parentheses of the expression (-2+2w+4w)(-7) is removed using the distributive property and the resultant expression is -14-42w.

<h3>What is distributive property?</h3>

The distributive property says that the product of a number and sum of two numbers is equal to the addition of the product of that number with the individual number of the sum.

c×(a+b)=ac+ab

The given expression in the problem is,

(-2+2w+4w)(-7)

Now, use the distributive property to remove the parentheses as,

(-2+2w+4w)(-7)

-2×-7+2w×-7+4w×-7

-14-14w-28w

-14-42w

Hence, the parentheses of the expression (-2+2w+4w)(-7) is removed using the distributive property and the resultant expression is -14-42w.

A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?
Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}

The tax is 8%. So this is from the marked price.

\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}

Therefore the total cost of the tent is $225.39.

A TV and Washing machine were purchased for Rs 15000 each. If together, they are sold at Rs 35000, What is Profit and Profit%
Citrus2011 [14]

Given:

A TV and Washing machine were purchased for Rs 15000 each.

Together, they are sold at Rs 35000.

To find:

The profit and profit%.

Solution:

A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is

C.P.=15000+15000

C.P.=30000

Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.

Now,

Profit=S.P.-C.P.

Profit=35000-30000

Profit=5000

And,

Profit\%=\dfrac{Profit}{C.P.}\times 100

Profit\%=\dfrac{5000}{30000}\times 100

Profit\%=\dfrac{50}{3}

Profit\%\approx 16.67

Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.

I think you are doing limits so this is what I did
and that's how I factored using the box method because it's easier to track distribution.

What’s .75% of .96 and is it the same as 3/4 of .96
Nadya [2.5K]

.75% of .96 = 0.0072

but if you meant .75% of .96% then it = 0.000072

and 3/4 of .96= 0.72

but if you meant 3/4 of .96% then it = 0.0072

so then yes it would be the same ..
