-5v-6=3v+10 i really hate math but i need help

Answers


OK.  We could have gotten along nicely without the comment.

-5v - 6 = 3v + 10

I think what you're trying to find is the number that ' v ' must be
in order to make the equation a true statement.  That number
is called the 'solution' of the equation.

To find it, you have to massage and manipulate the equation around
until you have ' v ' and nothing else on one side.  You can do anything
you want to a whole side of the equation, but whatever you do to one
side, you must immediately do to the other side.  Here's one way you
could go about it:

                                            -5v - 6 = 3v + 10

Add  5v  to each side:                 -6 = 8v + 10

Subtract  10  from each side:    -16 = 8v

Divide each side by  8 :             -2  =  v

Two boats on opposite banks of a river start moving towards each other. They first pass each other 1400 meters from one bank. They each continue to the opposite bank, immediately turn around and start back to the other bank. When they pass each other a second time, they are 600 meters from the other bank. We assume that each boat travels at a constant speed all along the journey. Find the width of the river?

Answers

assuming that the river doesn not move
if they kept a constand speed then they passes
the problem doesn't say how fast they were moving, but we can see that 1 boat is faster so

first pass
1400 meters from 1 bank
if they turn around they are 600 meters from the other bank
since they kept constant speed, they passed in the same place so
distance from bank1 to markx=1400
distance from bank2 to markx=600
distance from bank1 to bank2=600+1400
1400+600=total distance=2000 m

A conference room is in the shape of a rectangle. Its floor has a length of (x − 4) meters and a width of (3x − 1) meters. The expression below represents the area of the floor of the room in square meters: (x − 4)(3x − 1) Which of the following simplified expressions represents the area of the floor of the conference room in square meters?

Answers

You have to foil. Times the first two: x(3x). Then times the outer two: x(-1). Then times the inner two: -4(3x). Finally, times the last two: -4(-1). Your equation would be 3x squared - 1x - 12x + 4. Therefore, the simplified answer is 3x^2 (3x to the second power) - 13x + 4.

Answer:

Simplified expressions which represents the area of the floor of the conference room in square meters is:

3x²-13x+4

Step-by-step explanation:

A conference room is in the shape of a rectangle.

Its floor has a length of (x − 4) meters and a width of (3x − 1) meters.

we know that Area of rectangle=Length×Breath

Area of floor of the room=(x-4)(3x-1)

(x-4)(3x-1)=x(3x-1)-4(3x-1) (Distributive property)

               = 3x²-x-12x+4   (Distributive property)

              = 3x²-13x+4   (On combining the like terms)

Hence, simplified expressions which represents the area of the floor of the conference room in square meters is:

3x²-13x+4

Elsa knows that for every bushel of apples she sells she earns $9 and for every basket of pears she earns $11. She uses the expression 9a + 11p to keep track of her earnings. Part A: Identify the coefficients and variables in the expression. (3 points)

Part B: How many terms are in the expression, what are they, and how do you know? (4 points)

Part C: Which term in the expression shows the total earned from selling baskets of pears? (3 points)

Answers

A. Variables are A and P and the coefficiants are 9 and 11

B. 2 terms , 9a and 11p , there are 2 "groups" that are separated by the addition sign

C. 11p shows the total earned you would just have to plug in the amound of baskets of pears on for p and multiply 11 and p to find out the amount earnes
The coefficients are 9 and 11 since they are multiplied by a variable; the variables are a and p since a and p are unknown.
There are two terms in the expression. The terms are 9a and 11p. They can be a separate part of an equation, a series, or another expression.
11p is the term that shows the total earned from selling baskets of pears since $11 is how much Elsa gets for every basket of pears.
