2(3x - 4) = 2x + 12

6x - 8 = 2x + 12

4x = 20

x = 5

AB = 3(5) - 4 = 11

AC = 2(5) + 12 = 22

BC = 7(5) - 2 = 35 - 2 = 33

AC:BC = 22:33 = 2:3

What are the solutions of the equation x^6-9x^3+8= 0 use u substitution to solve
labwork [276]

Answer: x = {1, 2}

<u>Step-by-step explanation:</u>

x⁶ - 9x³ + 8 = 0

Let u = x³  

⇒ (x³)² - 9(x³)¹ + 8(x³)⁰ = 0

⇒ u² - 9u + 8 = 0

⇒ (u - 1)(u - 8) = 0

⇒ u = 1 or u = 8

Replace u with x³

x³ = 1     or   x³ = 8

Take the cubed root of each side

x = 1     or     x = 2

Help me I need the answer on paper help me now
Viktor [21]

Answer:

a) k = 10              b) k = 7.5

Step-by-step explanation:

<h3><u><em>a)</em></u></h3>

( 5k+ 20 ) + ( 7k + 40 ) = 180

12k + 60 = 180

12k = 120

k = 10

<h3><u><em>b)</em></u></h3>

40 + ( 12k + 10) + 180 - ( 8k + 80 ) = 180

50 + 12k + 180 - 8k - 80 = 180

50 + 12k -8k - 80 = 0

50 + 4k - 80 = 0

30 = 4k

k = 7.5

Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg. How many toys did
Vilka [71]

Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.

Let the number of toys Oleg has = x

Let the number of toys Sasha has = y

Let the number of toys Dima has = z

Sasha had twice as many toys as Oleg

So y = 2*x= 2x

Dima had 40 more toys than Oleg.

z = x + 40

Oleg, Sasha, and Dima shared 600 toys

x + y + z= 600

We know y=2x and z=x+40

Replace it for y and z

x + y + z = 600

x + 2x + x + 40 = 600

4x + 40 = 600

Subtract 40 on both sides

4x =  600 - 40

Divide by 4 on both sides

x = \frac{560}{4} = 140

Oleg had 140 toys

Miranda brought 24 cookies to share with her class. Two-thirds of the cookies are chocolate chip. How many are chocolate chip?
Digiron [165]
Hey there
SO we know that the total amount that she brought is 24 cookies.
we also know that 2/3 of the cookies are choco chip.
So to find the answer we need to divide 24/3 which gives us 8 so one third of 24 is eight if we multiply 8 by two we get 16 which is 2/3 of 24.
