13x+5y=90 what is x? what is y?

Leona [35]

Answer:

X=-5y/13+90/13, Y=-13x/5+18

Step-by-step explanation:

You need to solve the equation for X and Y.

Solving for X:

13x+5y=90

Subtract 5y: 13x=-5y+90

Divide by 13: x=-5y/13+90/13

For Y:

13x+5y=90

Subtract 13x: 5y=-13x+90

Divide by 5: y=-13x/5+90/5

(Simplifies to -13x/5+18)

name three different pairs of fractions that have the same product when multiplied .explain how you got your answer

Deffense [45]

$\frac{5}{10}*\frac{10}{40}=\frac{50}{400}$
$\frac{2}{8}*\frac{2}{4}=\frac{4}{32}$
$\frac{1}{4}*\frac{1}{2}=\frac{1}{8}$

$\frac{1}{8}$ is obtained by multiplying $\frac{1}{2}$ and $\frac{1}{4}$
You basically create equivelant fractions for both 1/2 and 1/4 and multiply by each other. This way you get the same result always.
