Answer:

Step-by-step explanation:

12 men and 18 women: x1; 14 days; y1

8 men and 16 women: x2; ?; y2

12/18 simplified is equal to 2/3

8/16 simplified is equal to 1/2

This is a direct proportion, thus we can say that:

(1/2*14)/(2/3)=y2

7/(2/3)=10.5 days

I hope this helped you get out of homework trouble :D

Answer:

(x -t -250)/2

Step-by-step explanation:

The amount left from x after paying t and 250 is ...

What is the interest if a sum of $5200 is invested for 36month at 15% per annum

Serggg [28]

Answer:

I = 2,340

Step-by-step explanation:

The formula for interest is

I = P × R × T / 100

P = $5200

R = 15%

T= 36 months; T is meant to be in years so we will convert it from months to years

1 year = 12 months

So 36 months

= 36 /12 = 3 years

I = (5200 × 15 × 3)/100

I = 234,000 / 100

I = 2,340

The product of (4z^2 + 7z - 8) and (-z + 3) is -4z^3 + xz^2 + yz - 24. What is the value of x? What is the value of y?

ycow [4]

Answer:

$x=5+\frac{29}{z}-\frac{y}{z}$

$y=5z+29-xz$

Step-by-step explanation:

Given: $(4z^2+7z-8)(-z+3)=-4z^3+xz^2+yz-24$ ; find x and y.

Let's start with finding x first. Let's distribute the left side of the equation.

$-4z^3+5z^2+29z-24=-4z^3+xz^2+yz-24$

Let's move everything we can to the left side of the equation. Some things will cancel out.

$5z^2+29z=xz^2+yz$

Now, let's move the term that includes $x$ to the left side of the equation. Everything else should be moved to the right.

$-xz^2=-5z^2-29z+yz$

Let's get rid of the negative sign in front of $x$ by dividing both sides by -1.

$xz^2=5z^2+29z-yz$

To get $x$ completely isolated, divide both sides by $z^2$ .

$\frac{xz^2}{z^2}=\frac{5z^2}{z^2}+\frac{29z}{z^2}-\frac{yz}{z^2}$

Simplify.

$x=5+\frac{29}{z}-\frac{y}{z}$

Let's solve for y. We will start with the distributed and simplified equation to make it easier.

$5z^2+29z=xz^2+yz$

Now, let's move the term that includes $y$ to the left side of the equation. Everything else should be moved to the right.

$-yz=-5z^2-29z+xz^2$

Again, let's get rid of the negative sign in front of the $y$ by dividing both sides by -1.

$yz=5z^2+29z-xz^2$

To isolate y, divide both sides by z.

$\frac{yz}{z}=\frac{5z^2}{z}+\frac{29z}{z}-\frac{xz^2}{z}$

Simplify.

$y=5z+29-xz$
