What is the value of x in the equation 5x - 3x + 4(1-4x) = 32?

Step-by-step explanation:

So we have the equation:

First, subtract the 5x and 3x:

Distribute the 4:

Subtract:

Subtract 4 from both sides:

Divide both sides by -14:

And we're done!

x=-2

Step-by-step explanation:

5x - 3x + 4(1-4x) = 32

Distribute

5x - 3x + 4-16x = 32

Combine like terms

-14x +4 = 32

Subtract 4 from each side

-14x +4-4 = 32 -4

-14x = 28

Divide each side by -14

-14x/-14 = 28/-14

x = -2

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
