so first you distribute the 6 to wats inside the parenthesis

now you have 30-48v+12=-54

now add twelve and 30 and you now have 42-48v=-54

now subtract the 42 and you know have -48v=-96

now divide by -48 and you now have v=2

plz rate me brainliest by giving me 5 stars

V=2 bc when u distribute the 6 to the numbers in the parenthesis u get 30-48v+12=54 then u subract 12 on both sides getting 30-48v=-66 then u subtract 30 on both sides making it -48v=-96 and mental math leads to -48•2=-96

This item is $9000 dollar and it is 90% off how much is the item? Step by step?
Daniel [21]

Answer:

The item costs $900 after the 90% off.

Step-by-step explanation:

After the 90% off discount, the item costs (100% - 90%) the cost of the original price.

Hence, \$9000 \cdot (100\% - 90\%)

= \$9000 \cdot 10\%

= \$900

Hope this helped!

a seed company has a test plot in which it is testing the germination of a hybrid seed, They plant 50 rows of 40 seeds per row.
ziro4ka [17]

Answer:

Mean =\sum x P(x) = 36.86

Standard deviation =\sum x^2P(X)=1360.9

Step-by-step explanation:

x          P(x) x \times P(x)       x^2 \times  P(x)

33         0.02     0.66          21.78

34          0.06     2.04         69.36

35           0.1      3.5        122.5

36           0.2      7.2         259.2

37           0.24     8.88        328.56

38           0.26     9.88        375.44

39            0.1     3.9         152.1

40            0.02     0.8         32

             1        36.86      1360.9

We are supposed to find mean and standard deviation

Mean =\sum x P(x) = 36.86

Standard deviation =\sum x^2P(X)=1360.9

What is the equation of the line with the same slope as the equation x-4y=3 and the y-intercept(0,-8)?
katen-ka-za [31]

Answer:

y = 1/4x -8

Step-by-step explanation:

First find the slope of the line

x-4y =3

Subtract x from each side

x-4y -x = -x+3

-4y = -x+3

Divide each side by -4

-4y/-4 = -x/-4 +3/-4

y = 1/4 x -3/4

This is in the form y= mx+b where the slope is m and the y intercept is b

The slope is 1/4

We want the same slope

y = 1/4x +b

we know the y intercept is -8

y = 1/4x -8
