Multiply everything in the parenthesis by a.
ac + ab = d
Subtract ab from both sides.
ac = d - ab
Divide a on both sides.
c = d - ab / a

When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Hope this helps!
Go 0.35•22 and you get 7.7
Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:
Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.
Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.
The red car can travel farther on 1 gallon of gas.
Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52 cards in each deck
- We need how many cards in total
So let us think about it from a mathematical standpoint
1 deck= 52 cards 1 x 52= 52
that means.....
2 deck= 104 cards 2 x 52 = 104
3 deck= 158 cards 3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d
