If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.

ziro4ka [17]

Answer:

$y=-5x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

For $x=6,y=-30$

substitute

$y/x=k$ ------> $k=-30/6=-5$

therefore

$y=-5x$

Valentin [98]

Answer:

I think number 1=209

number 2=120

number 3=89

Step-by-step explanation:

x= 1st aircraft

y=2nd aircraft

z=3rd aircraft

x=y+89

y=z+31

z=y-31

x+y+z=418

y+89+z+31+y-31=418

2y+89+z=418

2y+z=329

2y+(add z)

2y+y-31=329

3y=360

y=120

x=120+89=209

z=120-31=89

Josue knows that his aunt earns more money. than his uncle. He asked how much his aunt earns each month and was told, "$600 less

Firdavs [7]

Answer:

Uncle's earnings is $2400

Step-by-step explanation:

Represent his uncle's earnings with x

$600 less than twice what your uncle earns is represented as:

$2x - 600$

Since, his aunt's earnings is $4200.

We have:

$2x - 600 = 4200$

Add 600 to both sides

$2x - 600 + 600= 4200 + 600$

$2x = 4800$

Solve for x

$x = 4800/2$

$x = 2400$

<em>Hence, His uncle's earnings is $2400</em>
