<span>(-3x^3 y^2)(5xy-1)
Taking variables and coeffecients to one side:
{(-3)(5)} {(x^3 * x)} {(y^2 * y^-1}
{-15} { x^3+1} { y^2-1}
{-15} {x^4} {y^1}
-15x^4y
So according to above explanation.

Answer:
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86
Step-by-step explanation:
Let
x ----> the amount invested at 6%
30,000-x -----> the amount invested at 13%
we know that
The interest earned by the amount invested at 6% plus the interest earned by the amount at 13% must be equal to the interest earned by the total amount of $30,000 at 10%
Remember that
so
The linear equation that represent this situation is
solve for x
therefore
The amount invested at 6% is $12,857.14
The amount invested at 13% is $17,142.86
X=60 Because 10+90 is 100 and 160-100 is 60, which is the number of players who play tennis and cricket.
The length of the base is 10 and the length of each leg is 20.
In order to find this, we can start by making the length of the base x. Now we know that the legs are twice as long, which would make them 2x. Since there are two of them, we can add x + 2x + 2x and set equal to 50 to find the value of x.
x + 2x + 2x = 50
5x = 50
x = 10
Now we can plug this in for our leg length as well to find that.
2x = Leg
2(10) = Leg
20 = leg
