Answer:

16.33333333333333333333333333333................

Step-by-step explanation:

First, set up the equation with the known y value like so, 3x+4(4)=65

Next, multiply: 3x+16=65

Then, subtract 16 from both sides: 3x=49

Last, divide both sides by three:x=16.33333333333333333333333333.......

I hope this helps you

Answer:

The value of x if the equation is

3x + 4y=65

x = 49/3 or 16.3

3x - 4y=65

x= 27

1. Find the Least Common Multiple of these two monomials: See picture

gtnhenbr [62]

Answer:

The last choice is correct

$LCM=120a^4b^7c^5$

Step-by-step explanation:

Least Common Multiple (LCM)

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

$12a^4b^2c^5$

$40a^3b^7c^1$

The prime factors of the first monomial are:

$2^2,3,a^4,b^2,c^5$

The prime factors of the second monomial are:

$2^3,5,a^3b^7c^1$

LCM = Multiply $2^3*3*5*a^4*b^7*c^5$

These are all the factors the greatest number of times they occur.

Operating:

$LCM=8*15*a^4*b^7*c^5$

$\boxed{LCM=120a^4b^7c^5}$

The last choice is correct
