Bottles of sparkling water usually cost $1.69 each. This week they are on sale for 4 for $5. What is the unit price of the bottles now that they are on sale?

Answer:

x+y=28

70x+140y=3360

8 cats, 20 dogs were sold

Step-by-step explanation:

Let x=cats y=dogs

We know that a total of 28 pets were sold which means that

x+y=28

We also know that they made 3360 which means that

70x+140y=3360

It doesn't really say if you need to solve this but I will anyways

We use the first equation (x+y=28) and subtract 28 and y from both sides to get

x-28= -y we can then divide both sides by -1 so y can be a positive

-x+28=y

This is what y equals in terms of x and so we can plug this in for y in the second equation

70x+140(-x+28)=3360

Distribute the 140 and get

70x-140x+3920=3360

Add like terms and subtract 3920 to get

-70x=-560

divide both sides by -70 and get

x=8

We now know that 8 cats were sold and can plug this value into any equation to solve for y ( I will be using the first one because that's easiest)

8+y=28

subtract 8 and get

y=20

A system of equations that matches the situation is:

1) d + c = 28.................Equation 1

2)140d + 70c = 3360............Equation 2

This question has to do with Algebraic equations.

Let's represent

Number of dogs = d

Number of cats  = c

A pet store is selling dogs for $140 and cats for $70. If 28 pets were sold and they made $3,360.

We have two algebraic systems of equations for the above statements

1) d + c = 28.................Equation 1

2) $140 x d + $70 x c = $3,360

140d + 70c = 3360............Equation 2

Answer:

Area of triangle = 20 square yards

Step-by-step explanation:

The height of triangle = 5 yd

The base of triangle = 8 yd

We need to find area of triangle.

The formula used is: [tex]Area\: of\: triangle=\frac{1}{2}\times base \times height[/tex]

Putting values and finding area

[tex]Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards[/tex]

So, Area of triangle = 20 square yards

A log function is a way to find how much a number must be raised in order to get the desired number. The correct option is A.

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]a^c =b[/tex]

can be written as

[tex]\rm{log_ab=c[/tex]

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

For example, let's assume we need to raise the power for 10 to make it 1000 in this case log will help us to know that the power must be raised by 3.

The solution set of the given equation can be found as shown below.

log₄(x-3) + log₄(x+3)=2

log₄[(x-3)(x+3)] = 2

Taking antilog,

(x-3)(x+3) = 4²

(x-3)(x+3) = 16

x² - 3² = 16

x² = 16 + 3²

x² = 25

x = ±5

Substitute the value of x as -5 and 5, to verify if the equation is verified.

The only value for which the equation is satisfied is 5.

The above solution can be verified by plotting the graph.

Answer:

I agree with the other person. I answered with the exact same answer so yes it is indeed 5.5!

Step-by-step explanation:

Answer:

a)  ( r+ s) (x)  = 3 x + 9

b)   ( r . s ) (x) =  2 x² + 13 x +20

c) ( r- s) (x)  = -1 -x

Step-by-step explanation:

Step(i):-

Given that r(x) = x +4 and s(x) =  2x + 5

a)   ( r+ s) (x)  = r(x) + s(x)

                    = x +4 + 2x +5

                   = 3 x + 9

    ( r+ s) (x)  = 3 x + 9

b)

    ( r . s ) (x)  = r(x) . s(x)

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

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

                  = 2 x² + 5 x + 8 x +20

                 = 2 x² + 13 x +20

( r . s ) (x) =  2 x² + 13 x +20

c)

 ( r- s) (x)  = r(x) - s(x)

               =  (x+4 - ( 2x +5)

              = x +4 - 2x -5

            = -x -1

( r- s) (x)  = -1 -x
