Answer:

$\large\boxed{4x+6y^3}$

Step-by-step explanation:

$2x+x+x+2y\times3y\times y\\\\=(2x+x+x)+(2y\times3y\times y)\\\\=4x+(2\times3)(y\times y\times y)\\\\=4x+6y^3$

I just need help set up

Vilka [71]

Answer:

Step-by-step explanation:

Set up equations (L= Lisa; M = Maria; A = April; J = Jim)

L = 12M

A = 2J

Substitute x for Maria and 6x for Jim

L = 12x

A = 2(6x) = 12x

So, you get:

Maria = x

Jim = 6x

Lisa = 12x

April = 12x

What is the value of k in the equation 2/7(k+5/8)=2 2/7

shusha [124]

2/7 ( k+5/8) = 2 and 2/7

2/7 (k+5/8) = 16/7 |multiply by 7

2(k+5/8) = 16 |divide by 2

k+5/8 = 8 |subtract 5/8

k=8-5/8 = 7 and 3/8 = 27/8 = 7.375
