Step-by-step explanation:

Answer:

x + 5 = 5×

7x - 5 = 2x

5x + 2x + x = 180

8× = 180

8 8

x = 22.5

Answer: y = -x-8

Step-by-step explanation:

(-3,-5) (-5,-3)

Slope (m) = (y-y)/(x-x) = (-3- -5)/(-5- -3) = (-3+5)/(-5+3) = 2/- 2 = - 1

m = - 1

Point (-3,-5)

y-y=m(x-x)

y- -5= -1(x- -3) = y+5 = -1(x+3)

y+5 = - x -3

y+5= - x - 3 (substract 5 from both sides)

y = - x - 8

Answer:

y = (x+8)(x+3)

Step-by-step explanation:

The equivalent expression to the given quadratic equation is:

y = (x + 8)*(x + 3).

Here we start with:

[tex]y = x^2 + 11x + 24[/tex]

To solve the problem, we need to find the roots of the quadratic equation, to do it, we will use the Bhaskara's formula:

[tex]x = \frac{-11 \pm \sqrt{11^2 - 4*24} }{2} \\\\x = \frac{-11 \pm 5 }{2}[/tex]

Then the two solutions are:

Meaning that we can write the cuadratic equation as:

y = (x + 3)*(x + 8).

So the correct option is the first one.

Answer: [tex]\$60[/tex]

Step-by-step explanation:

Given

One ticket costs $20

Susan buys 4 tickets with 25% discount

Cost of 4 tickets is [tex]4\times 20=\$80[/tex]

On applying discount, it costs

[tex]\Rightarrow 80-80\times 0.25\\\Rightarrow 80(1-0.25)\\\Rightarrow 80\times 0.75=\$60[/tex]

So, total cost of tickets is [tex]\$60[/tex].

Answer:

r = 7

y = -2

Step-by-step explanation:

9r + 2y = 59 (Multiply this by 5)

2r + 5y = 4   (Multiply this by -2)

45r + 10y = 295

-4r - 10y = -8

41r = 287

r = 7

2r + 5y = 4

2(7) + 5y = 4

14 + 5y = 4

5y = 4 - 14

5y = -10

y = -2

Answer:

[tex]x^2 + 6 = 31[/tex]

Step-by-step explanation:

Given

[tex]Painted = 6ft^2[/tex]

[tex]Total = 31ft^2[/tex]

Dimension of unpainted area:

[tex]Length = Width = x[/tex] --- Square

Required

Determine an expression to solve for x

First, calculate the area of the unpainted space;

[tex]Area = Length *Width[/tex]

[tex]Area = x*x[/tex]

[tex]Area = x^2[/tex]

The unpainted area, added to the painted area, equals the total area.

So, we have:

[tex]Area + Painted = Total[/tex]

[tex]x^2 + 6 = 31[/tex]

Hence, the expression is: [tex]x^2 + 6 = 31[/tex]

Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

In mathematics, the unitary approach entails determining the value of a single unit and then using that value to determine the value of a certain number of units. It is frequently applied to issues concerning rates and proportions as well as issues relating to ratios and proportions. The unitary method, for instance, would result in a cost of $5 for 5 apples if the price of 1 apple is $2. To calculate the overall cost using the unitary method, we would multiply the $2 worth of one apple by the quantity we wish to purchase. Therefore $5 would be spent on 5 apples, or $2 each.

given

Assume that "x" represents the total quantity of flowers sold on that particular day.

Roses made up 35% of the total number of flowers, which means that:

0.35x = 42

By dividing both sides by 0.35, we can determine the value of "x":

x = 120

Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

Answer:

C. 1/3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

Identify

a = 2/3

b = 3/4

c = 1/2

a(b - c²)

Step 2: Evaluate

Answer:

C. 1/3

Step-by-step explanation:

Replace each letter with their corresponding value and simplify using the order of operations:

a(b - c*c)

turns into:

[tex]\frac{2}{3} (\frac{3}{4}-(\frac{1}{2}*\frac{1}{2}))[/tex]

You want to remember that order of operations follows the rules of PEMDAS. The operations within the parentheses come first.

1/2 times 1/2 = 1/4

Now we have:

[tex]\frac{2}{3}(\frac{3}{4}-\frac{1}{4})[/tex]

Then 3/4 - 1/4 = 2/4 = 1/2

[tex]\frac{2}{3}(\frac{1}{2})[/tex] = 1/3

Therefore your answer is C. 1/3
