Answer:

[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]

Step-by-step explanation:

Given that:

Last Sunday a certain store sold copies of Newspaper A for $1.00 each

A = 1

and copies of Newspaper B for $1.25 each,

B = 1.25

and the store sold no other newspapers that day. If r percent of the store's revenue from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of Newspaper B.

Then ;

[tex]r = \dfrac{A}{A+1.25B} \times 100[/tex]  --- (1)

[tex]p = \dfrac{A}{A+B} \times 100[/tex]        --- (2)

From (2)

[tex]A+B = \dfrac{A}{p} \times 100[/tex]

[tex]B = \dfrac{A}{p} \times 100-A[/tex]

[tex]B = \dfrac{A( 100-p)}{p}[/tex]

Substituting the value of B into equation (1), we have:

[tex]r = \dfrac{A}{A+1.25 \times { \dfrac{A( 100-p)}{p}}} \times 100[/tex]

[tex]r = \dfrac{A}{A+1.25 \times { A( 100-p)}} \times 100p[/tex]

[tex]r = \dfrac{100p}{p+125 -1.25 p}[/tex]

[tex]r = \dfrac{100p}{125 -0.25 p}[/tex]

multiplying both numerator and denominator by 4; we have

[tex]r = \dfrac{4(100p) }{ 4(125 -0.25) p}[/tex]

[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]

Answer:

no solution

Step-by-step explanation:

Given

4 + x = 3(x + 2) - 2x ← distribute and simplify right side

4 + x = 3x + 6 - 2x

4 + x = x + 6 ( subtract 4 from both sides )

x = x + 2 ( subtract x from both sides )

0 = 2 ← not possible

This indicates the equation has no solution

Answer:

a = -3, b = 6

Step-by-step explanation:

ax + 6 = -3x + b

If a = -3 and b = 6, then the equation would be -3x + 6 = -3x + 6, which would have infinitely many solutions.

If we isolate x, we have (a + 3) x = b - 6. We want the equation to be 0 = 0 for infinitely many solutions, so a has to be -3 and b has to be 6.

9Answer: Y-1=-2(X+1) OR Y+9 = -2(X-4)

Step-by-step explanation:

Point slope form is Y-Y1=m(X-X1)

Slope (M) is (Y2-Y1)/(X2-X1)

SO M= (-9-1)/(4--1)

-10/5

M= -2

Answer:

y - 1 = -2 (x + 1)

Explanation:

point slope form: (y - y1) = m (x - x1)

m is the slope. To find m the formula is:

             (y2 - y1) / (x2 - x1)

The given ordered pairs are: (-1,1) and (4,-9)

y2 is the y in the second ordered pair (-9)

y1 is y in the first ordered pair (1)

x2 is x in the second ordered pair (4)

x1 is x in the first ordered pair (-1)

                = (-9 - 1) / (4 +1)

                 = -10/5

             m = -2

Now plug m (-2), y1 (1), and x1 (-1) into the point slope form

y - 1 = -2 (x - -1)

y - 1 = -2 (x + 1)

Answer: x=-6

Step-by-step explanation:

9(x+3)=4x-3

9x+27=4x-3 ⇔ distributive property (take off parentheses)

5x+27=-3 ⇔ subtraction property of equality (subtract 4x on both sides)

      5x=-30 ⇔ subtraction property of equality (subtract 27 on both sides)

        x=-6

Hope this helps!! :)

Please let me know if you have any question

Answer:

simplify both sides and get 9x+27=4x+−3 then subtract 4x and get  5x+27=−3 and subtract -27 and divide answer by 5 to get x=-6

Answer:

3.)

•What do you know?

-It’s about 425 miles from San Jose to Los Angeles and 320 miles from San Jose to Santa Barbara.

•What do you want to find out?

-How many miles it is from Santa Barbara to Los Angeles.

•What kind of answer do you expect?

-If using variable, I expect that I will get the number of miles from one city to the other.

5.)

425 = 320 + X

6.)

425 = 320 + X

Subtract 320 from both sides.

7.)

X = 105

From Santa Barbra to Los Angeles it is 105 miles.

8.)

320 + 105 = 425

Answer: The value of x=1.

Measure of CD =1 unit.

Step-by-step explanation:

Given: Segment EC bisects segment AD at C.

That means , EC divided AD into two equal parts AC and CD,

i.e. [tex]AC=\dfrac{AD}{2}[/tex]  

Also it is given that [tex]AD = 6x - 4[/tex] and [tex]AC = 4x - 3.[/tex]

then, we have

[tex]4x-3=\dfrac{6x-4}{2}\\\\\Rightarrow\ 4x-3= 3x-2\\\\\Rightarrow\ 4x-3x=-2+3\\\\\Rightarrow\ x= 1[/tex]

So, the value of x=1.

Now,  CD = AC = 4(1)-3 =4-3 =1 unit.

Hence, Measure of CD =1 unit.

Answer:

169.2cm

Step-by-step explanation:

56.4cm + 56.4=  112.8+ 56.4=   169.2cm

The combined height of the 3 stacked boxes will be 169.2 cm so option (D) will be correct.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

Height of one box = 56.4 cm

So,

Height of two boxes = Height of one box + Height of one box

It means

Height of three boxes = Height of one box + Height of one box + Height of one box

So,

Height of three boxes = 56.4 +  56.4 +  56.4

Height of three boxes = 169.2 cm

Hence "The combined height of the 3 stacked boxes will be 169.2 cm".

Answer:

32

Step-by-step explanation:

We are given the expression:

[tex]\frac{-8(13-37)}{6}[/tex]

and asked to evaluate the expression.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve inside the parentheses first. Subtract 37 from 13.

⇒ 13-37= -24

[tex]\frac{-8(-24 )}{6}[/tex]

Next, multiply -8 and -24.

⇒ -8*-24= 192

[tex]\frac{192}{6}[/tex]

Finally. divide 192 by 6.

⇒ 192/6 = 32

[tex]32[/tex]

When evaluated, the expression -8(13-37)/6 is equal to 32.

Answer:

She would have 130 dollars

Step-by-step explanation:

There are 52 weeks in a year. So multiply 2.50 by 52. She would have 130 dollars.

Ashley can expect to save $130 for the trip in exactly one year.

Ashley decided to stop eating chocolate for one whole year to save some spending money for her senior class trip to Mexico.

The amount Ashley typically spends a week on chocolate =  $2.50.

We have to find how much Ashley can save in one year if we can save $2.50 per week.

There are 365 days in a year and we have 7 days in a week.

If we divide 365 by 7 we get,

365 / 7 = 52.14.

which means 52 weeks.

So in one year, we have 52 weeks.

We can write this statement "Ashley typically spends $2.50 a week on chocolate" as :

1 week = $2.50

Multiply by 52 on both sides.

we get,

52 x 1 week = 52 x $2.50

52 weeks = $130

Thus, we can say that in one year Ashley can save around $130 if she saves $2.50 in a week.
