If Y is inversely proportional to x and y=4 when x= 100, what is the value of y when x=250

hichkok12 [17]

Answer:

y=10

Step-by-step explanation:

$\frac{4}{100}$ = $\frac{y}{250}$

cross-multiply, 4*250=100y

isolate the variable and solve for y, 1000=100y

divide 100 on both sides, 10=y

x + y = -9

x + 2y = -25

Rewrite the first equation as x = -9-y

Relace x in the second equation:

-9-y + 2y = -25

Simplify:

-9 +y = -25

Add 9 to both sides:

y = -16

Now you know y,, replace y in the first equation and solve for x:

x -16 = -9

Add 16 to both sides:

x = 7

Answer: x = 7
