Answer:

9 people

Step-by-step explanation:

Start by writing an equation.

The total bill is 134.03. The bill is totally paid by Marcus and the other guests. This will go on the other side of the equation.

Since we don't know how many guests there were, we can use variable x to represent the value that we're trying to find.

So here is our equation.

134.04 = 20.45 + 12.62x

Now, just solve for x, or isolate x.

Subtract 20.45 from both sides.

134.04 - 20.45 = 12.62x

Divide both sides by 12.62.

113.59/12.62 = x

Simplify.

x = 9

Since x is 9, we know that there were 9 other people at the dinner party.

The length of a rectangle is 4x+1 and the width is 2x+5. Write an expression and simplify it in terms of x: whats the perimeter
enot [183]

Answer: ( P - 10 )/12, (2x + 5)(4x + 1)

Step-by-step explanation:

The length of the rectangle = 4x + 1,

The breadth = 2x + 5

Formula for finding perimeter of a rectangle, = 2( L + B )

Now, substitute for L and B in the formula, open the formula and simplify,

= 2(4x + 1 + 2x + 5 )

= 2(6x + 5 )

= 12x + 10

Therefore, the perimeter (p)of the rectangle, = 12x + 10.

If P = 12x + 10

12x = P - 10

x = ( P - 10 )/12

Area of a rectangle = L x B

=( 4x + 1 )( 2x + 5)

We therefore open the brackets

(4x + 1)(2x + 5)= 4x X 2x + 4x X 5+ 1 X 2x + 1 X 5

= 8x² + 20x + 2x + 5

A = 8x² + 22x + 5

A = (2x + 5)(4x + 1)

ella [17]
Hi, thank you for posting your question here at Brainly.

All you have to do to acquire the equation is to substitute the variables to the formula for A and simplify. Since A = 1/2*b*h and h = bsin(C), then A can be in terms of one variable only, which is b.

A = 1/2*b*bsin(c)
A = 1/2*b^2*sin(C)

a crew of highway workers paved 2/15 mile in 20 minutes.if they continued working at the same rate,what portion of a mile wil th
icang [17]

Answer:

2/5 of a mile

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than  

20 minutes. The longer the time, the more they will pave.


2/5  of a mile, in 20 minutes, how much in 60 minutes?(#)

They will pave 3 times more.

2/15 x 3/1 = 6/15 of a mile

6/15 = 2/5 of a mile

Answer the following 4 questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!
Shkiper50 [21]

1. A) 5 (It would be B. because it does equal 4.09 but it has to be 5 because it is the greatest integer in all of them)

2. D) 10 (Just like 1. it would be B. also BUT 10 is the greatest integer you can have out of all of them)

3. A) 6 (Just like the other 2 problems at the top^ it would be C. if not for the fact it has a higher number.)

4. A) A value we can put in place of a variable (such as x) that makes the equation true.
