The value of x from the given equation is 11.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 3x-5 = 2x + 6.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, 3x-5=2x+6

3x-2x=6+5

x=11

Therefore, the value of x from the given equation is 11.

Answer:

Improper fraction form:103/72 Mixed number form: 1 32/72 Decimal form: 1.4035 with 5 repeating

Step-by-step explanation:

The quadratic equation [tex]2 - 2x + x^2 = -3[/tex] in standard form is: [tex]x^2 - 2x + 5 = 0[/tex]

To write the quadratic equation[tex]2 - 2x + x^2 = -3[/tex] in standard form, we need to rearrange the terms such that the polynomial appears in the form:

ax^2 + bx + c = 0

where a, b, and c are constants.

First, we can simplify the left-hand side by rearranging the terms:

x^2 - 2x + 2 = -3

Next, we can add 3 to both sides of the equation to isolate the quadratic terms on the left-hand side:

x^2 - 2x + 5 = 0

Now we have the quadratic equation in standard form, where:

a = 1 (the coefficient of x^2)

b = -2 (the coefficient of x)

c = 5

This form makes it easier to analyze the properties and behaviour of the quadratic function and to solve for its roots or solutions using various methods like factoring, completing the square or quadratic formula.

The estimated sum of 9 5/9 and 3 2/5 is approximately 13, the difference is approximately 5.84, the product is approximately 32.49, and the quotient is approximately 2.82.

To estimate the sum, difference, product, and quotient of 9 5/9 and 3 2/5, we can convert the mixed numbers into improper fractions for easier calculations.

First, let's convert 9 5/9 into an improper fraction:

9 5/9 = (9 * 9 + 5) / 9 = 86/9

Next, let's convert 3 2/5 into an improper fraction:

3 2/5 = (3 * 5 + 2) / 5 = 17/5

Now, we can perform the calculations:

Sum:

86/9 + 17/5 = (86 * 5 + 17 * 9) / (9 * 5) = 590/45

Difference:

86/9 - 17/5 = (86 * 5 - 17 * 9) / (9 * 5) = 263/45

Product:

(86/9) * (17/5) = (86 * 17) / (9 * 5) = 1462/45

Quotient:

(86/9) / (17/5) = (86 * 5) / (9 * 17) = 430/153

To simplify the fractions and estimate the results, we can approximate them to the nearest whole number or decimal:

Sum ≈ 13

Difference ≈ 5.84

Product ≈ 32.49

Quotient ≈ 2.82

Answer:

Lenth=15, width=4/5

Step-by-step explanation:

SO first we wanna make a equation about ths

The length of a rectangle is 11 centimeters less than five times its width.

L = lenth

W= width

L=5w+11

so w(5w+11)

and you wanna solve it

skip cuz   im bad

w = 4/5 or w = -3

-3 is not possible so w = 4/5

L=15

check:

15*4/5=12

The dimensions of the rectangle are:

Length = 4 cm

Width = 3 cm

To solve this problem, we will represent each of the given dimensions using algebraic expressions as follows:

Let:

Width of the rectangle = w cm

Length of the rectangle = [tex](5w - 11)[/tex] cm

Area of the rectangle = 12 sq cm

Formula for area of a rectangle = length [tex]\times[/tex] width

Therefore:

[tex](5w - 11) \times w = 12\\5w^2 - 11w = 12\\5w^2 - 11w - 12 = 0[/tex]

Factorize:

[tex]5w^2 + 4w - 15w - 12 = 0\\w(5w + 4) -3(5w + 4) = 0\\(w - 3)(5w + 4)\\(w - 3) = 0\\w = 3[/tex]

or

[tex]5w + 4 = 0\\5w = -4\\w = -\frac{4}{5}[/tex]

Width of the rectangle cannot be a negative number, so we would go with:

[tex]w = 3[/tex] cm

The width of the rectangle is therefore 3 cm

Find the length by plugging in the value of w into [tex]5w - 11[/tex]

Length of the rectangle = [tex]5(3) - 11[/tex]

= [tex]15 - 11\\[/tex]

= 4

Length of the rectangle is 4 cm

Point A is located identifying the domain value of 1 and the range value of 2. Point B is located identifying the domain value of 3 and the range value of 1.

These points can be used to form a fraction, or ratio, representing the slope of a line. By using this ratio and the intercept, we can write the equation of the line.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

The two points for this problem are given as follows:

A(1, 2) and B(3, 1).

When x increases by 2, y decays by 1, hence the slope m is given as follows:

m = -1/2

m = -0.5.

Hence:

y = -0.5x + b.

When x = 1, y = 2, hence the intercept b is given as follows:

2 = -0.5 + b

b = 2.5.

Hence the equation is:

y = -0.5x + 2.5.

The graph of the inequality 5x + 4y ≥ 2 is a solid line with a slope of -5/4 passing through (0, 1/2), and the region above the line is shaded.

The graph of the inequality 5x + 4y ≥ 2 represents a region in the coordinate plane.

To determine the graph, we need to convert the inequality into slope-intercept form, which is in the form y = mx + b.

Let's solve the inequality for y:

5x + 4y ≥ 2

First, subtract 5x from both sides:

4y ≥ -5x + 2

Next, divide both sides by 4 to isolate y:

y ≥ (-5/4)x + 1/2.

Now we have the inequality in slope-intercept form.

The slope is -5/4, and the y-intercept is 1/2.

To graph this inequality, we draw a solid line with a slope of -5/4 passing through the point (0, 1/2).

Since the inequality is greater than or equal to, the line itself is included in the solution.

After drawing the line, we shade the region above the line because any point in that region will satisfy the inequality.

This is because any y-value greater than or equal to the y-values on the line will make the inequality true.

The number of pounds of fruit Cameron have in all is [tex]1\frac{3}{8}[/tex] pounds.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given that, Cameron has 3/4 pound of raspberries, 1/8 pound of blueberries, and 1/2 pound of blackberries to make a frit salad.

Now, the number of pounds of fruit Cameron have in all

= 3/4 + 1/8 + 1/2

= 6/8 +1/8 +4/8

= (6+1+4)/8

22.5 ≤ p ≤ 30

Step-by-step explanation:

So we know that in 2/3 hours, Carlos can write 3 to 4 pages.

First, lets find how many 2/3's are in 5. Lets divide 5 by 2/3.

[tex]\frac{5}{\frac{2}{3}}=7.5[/tex]

So there are 7.5 2/3's in 5.

Now, lets assume Carlos writes 4 pages per 2/3 hours consistently throughout that 5 hours. This would yield the maximum amount of pages Carlos can write in 5 hours.

7.5(4) = 30

So the maximum amount of pages Carlos can write in 5 hours is 30.

Now, lets assume Carlos writes 3 pages per 2/3 hours consistently throughout that 5 hours. This would yield the minimum amount of pages Carlos can write in 5 hours.

7.5(3) = 22.5

So the minimum amount of pages Carlos can write in 5 hours is 22.5.

Now we can write the information that we found as an inequality. Lets make p equal to the pages that Carlos can write in 5 hours.

22.5 ≤ p ≤ 30

Any value greater than to equal to 22.5 and less than or equal to 30 would be reasonable.
