Answer:

The value of x is 2.

Step-by-step explanation:

The key to this solution is to combine like terms.

2x-3 > 11-5x

There are lots of ways to combine them but the way I think would be the most simple would be to avoid negative numbers (although I personally enjoy it) but anyways,

First, you can add 5x to both sides of the inequality.

This would cancel out 5x and leave you with: 7x-3 > 11

The next terms that you can combine can be the constants. You can combine -3 and 11 and to do that, you add 3 on both sides. That would cancel 3 out and leave you with: 7x > 14

Now, the last step is to get x by itself and to do that, you divide 7 on both sides to get:

x > 2

I hope my explanation wasn't too confusing for you

What is 6(x+3)=2(2x+5)

koban [17]

Answer:

x = -4 ;

Step-by-step explanation:

6(x+3)=2(2x+5)

Distribution

6x+18 = 4x + 10

Subtract 4x on both sides

2x+18 = 10

Subtract 18 on both sides

2x = -8

Divided by 2

x = -4

Now if we have to substitute the value of X

6(-4+3)=2(-8+5)

Parenthesis first

6(-1) = 2(-3)

-6 = -6

A hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services. Write a function to

Taya2010 [7]

Simple,

you have a fixed rate of $25, meaning you get a haircut, it's $25

ANY other service is an extra $15

So, let's make the equation...

y=15x+25

Now, to just get a haircut it's $25.

But, let's say you get a haircut+shampoo

It'd be..

y=15(1)+25

y=$40

Another one..

You get a haircut+shampoo+highlight

y=15(3)+25

y=$70

And so on, and so forth.

The Versatech Corporation has decided to produce three new products. Five branch plants now have excess production capacity. The

Answer: provided in the explanation segment

Step-by-step explanation:

here i will give a step by step analysis of the question;

A: Optimization Formulation

given Xij = X no. of units of product i manufactured in Plant j, where i = 1,2,3 and J = 1,2,3,4,5

Objective function: Minimize manufacturing cost (Z)

Z = 31 X11 + 29 X12 + 32X13 + 28X14 + 29 X15 + 45 X21 + 41 X22 + 46X23 + 42X24 + 43 X25 + 38 X31 + 35 X32 + 40X33

s.t

X11 + X12 + X13 + X14 + X15 = 600

X21 + X22 + X23 + X24 + X25 = 1000

X31 + X32 + X33 = 800

X11 + X21 + X31 <= 400

X12 + X22 + X32 <= 600

X13 + X23 + X33 <= 400

X14 + X24 <= 600

X15 + X25 <= 1000

Xij >= 0 for all i,j

Yes, we can formulate this problem as a transportation problem because in transportation problem we need to match the supply of source to demand of destination. Here we can assume that the supply of source is nothing but the manufacturing capability of plant and demand of destination is similar to the demand of products.

cheers i hope this helps!!
