first we multiply both sides by 3, so we get 42=4y-6x, because the division and multiplication cancel each other out, then we move the variable to the other side, so we subtract 4 on both sides and cancel out 4y-4y, so we and up with -4y=-6x-42, then we can divide both sides by -4, so:

final answer: y=3/2x + 21/2

Answer:

Step-by-step explanation:

(x+4) ^ 1/3 = 7

We need to cube each side of the equation

(x+4) ^ 1/3 ^3= 7^3

x+4 = 343

Subtract 4 from each side

x+4-4 = 343-4

x = 339

The power raised on each side is 3

Why is 6/8 greater than 5/8 but less than 7/8

My name is Ann [436]

Simple!

Since we can observe that they all have the same denominators (bottom part) we can just observe the numerator (top part)

6 is indeed greater than 5, yes? So we can safely say that

6/8 > 5/8

Now the for the second part.

6 is smaller than 7, yes? So we can make the observation that

6/8 < 7/8

Hope that makes sense! (Be sure to thank me, plz)

P.S. If you want an example of unlike denominators, let me know. <span />

Find the surface area of the triangular prism below.

Lapatulllka [165]

Step-by-step explanation:

At first you need to take its lateral surface area by using the perimeter of base of the triangle and the height of prism.

Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.

Then that's your answer.
