(d/2) + (f/4) = 6
4*[ (d/2) + (f/4) ] = 4*6 ... see note below
4*(d/2) + 4*(f/4) = 4*6
2d + f = 24
2d + f - 2d = 24 - 2d
f = 24 - 2d

The final answer is f = 24 - 2d

Note: I multiplied both sides by 4 because this is the LCD (lowest common denominator). Multiplying both sides by the LCD will clear out the fractions.

If the density of a 35.cm3 block of wood is .85 g./ml calculate the woods mass.
Reil [10]
So the equation you're going to be using is mass = density x volume 
So the volume of your block is 35cm^3, and your density is .85g/ml 

so your equation would be 

mass=.85g/ml x 35cm^3 

your final answer is 29.75g/cm^3

Hope this helps :)

Justin deposited $2,000 into an account 5 years ago. Simple interest was paid on the account. He has just withdrawn $2,876. What
RSB [31]

Answer: 8.76%

Step-by-step explanation:

The formula to find the simple interest is given by :-

I=Prt, where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years).   (1)

Given : Justin deposited $2,000 into an account 5 years ago.

i.e. P = $2,000 ,  t= 5 years

He has just withdrawn $2,876. i.e. Future value = $2,876

Interest (I)=$2,876-$2,000=$876  [Subtract Principal value from Future value]

Substitute all the above values of P , t , and I in the formula (1) , we get

876 =(2000)r(5)\\\\\Rightarrow\ r=\dfrac{876 }{2000\times5}\\\\\Rightarrow r=\dfrac{876}{10000}=0.0876

In percent , r=0.0876\times100=8.76\%

Hence, the rate of interest = 8.76%

Seven less than two times a number is 29.
Alexxx [7]
2x-7=29

"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together, 

-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)
