Solve for W -5.1=1.3+w/4

1 answer:

7 0

-5.1=1.3+w/4
Subtract 1.3 from both sides
-6.4=w/4
Multiply both sides by 4
-25.6=w

Check work:
-5.1=1.3+(-25.6/4)
-5.1=1.3+(-6.4)
-5.1=1.3-6.4
-5.1=-5.1

Hope this helps! :)

Y is inversley proportionaly to x. when y=7, x=9

mrs_skeptik [129]

The equation is y = 63/x

And y = 3 when x=21

Step-by-step explanation:

When y varies inversely with x, The inverse proportion is given by:

y ∝1/x

When the proportionality symbol is removed, a constant of proportionality is introduced

$y = \frac{k}{x}$

Putting y = 7 and x = 9

$7 = \frac{k}{9}\\k = 9*7\\k = 63$

So,

$y = \frac{63}{x}$

Putting x =21

$y = \frac{63}{21}\\y = 3$

Hence,

The equation is y = 63/x

And y = 3 when x=21

HELP PLSSSS I DONT UNDERSTAND WALLAH

Harlamova29_29 [7]

Answer:

7.2

Step-by-step explanation:

Distance between (4, 3) and (8, 9):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(8 - 4)^2 + (9 - 3)^2}$

$d = \sqrt{(4)^2 + (6)^2}$

$d = \sqrt{16 + 36}$

$d = \sqrt{52} = 7.2$ (nearest tenth)
