Answer:

21x+53

Step-by-step explanation:

The simplified expression is 21x - 13.

To solve the expression 5(3x + 4) - 3(-2x + 11), follow these steps:

Distribute the 5 into the first set of parentheses:

5 × 3x = 15x

5 × 4 = 20

So, 5(3x + 4) becomes 15x + 20.

Distribute the -3 into the second set of parentheses:

-3 × -2x = 6x

-3 × 11 = -33

So, -3(-2x + 11) becomes 6x - 33.

Combine like terms:

(15x + 6x) + (20 - 33) = 21x - 13

The simplified form of the expression is 21x - 13.

Answer:

176.6 mm^2

Step-by-step explanation:

We need to find the radius

r = d/2

r = 15/2 = 7.5

We want the area of a circle

A = pi r^2

A = pi * (7.5)^2

   = 3.14 * 56.25

    =176.625

Rounding to the nearest tenth

176.6 mm^2

Answer:

Table #1:

Length (L) | Width (W) | Area (56)

Table #2:

Length (2L) | Width (2W) | Perimeter (36)

Equation #1: L · W = 56

Equation #2: 2L + 2W = 36

Step-by-step explanation:

The following are the formulas used to find the area and the perimeter of a rectangle:

Area = L · W

Perimeter = L + L + W + W

If you group common variables, you can simplify the formula used to find the perimeter down to:

Perimeter = L + L + W + W

Perimeter = 2L + 2W (Since you're adding 2 of each)

Using these formulas, we can insert our values into them. We know that the rectangle has an area of 56 square inches meaning:

L · W = 56

We know that the rectangle has a perimeter of 36 inches meaning:

2L + 2W = 36

Answer:

Table #1:

Length (L) | Width (W) | Area (56)

Table #2:

Length (2L) | Width (2W) | Perimeter (36)

Equation #1: L · W = 56

Equation #2: 2L + 2W = 36

Answer:

The original number of oranges purchased is 260

Step-by-step explanation:

Let the original number of oranges purchased be x

We are given that The number of oranges a grocery store bought this year was 15% more than the number of oranges bought last year.

So, Oranges bought this year = [tex]x+15\%x=x+\frac{15}{100}x=1.15x[/tex]

We are given that This year the store bought 299 oranges.

So, [tex]1.15 x= 299[/tex]

[tex]x=\frac{299}{1.15}[/tex]

x=260

Hence the original number of oranges purchased is 260

32/5

Step-by-step explanation:

Answer:

The tenth term is

[tex] \frac{1}{20} [/tex]

Step-by-step explanation:

The 3rd term of an AP is 1/16.

This implies that:

[tex]a + 2d = \frac{5}{16} - - - (1)[/tex]

The 6th term of an AP is 1/5.

This means that:

[tex]a + 5d = \frac{1}{5} - - - (2)[/tex]

Subtract equation 1 from equation 2.

[tex]5d - 2d = \frac{1}{5} - \frac{5}{16} [/tex]

[tex]3d = - \frac{9}{80} \\ \implies \: d = - \frac{3}{80} [/tex]

From equation (1)

[tex]a + 2( - \frac{3}{80} )= \frac{5}{16} \\ a - \frac{3}{40} = \frac{5}{16} \\ a = \frac{5}{16} + \frac{3}{40} \\ a = \frac{31}{80} [/tex]

The tenth term is:

[tex]a + 9d = \frac{31}{80} + 9( - \frac{3}{80} ) \\ = \frac{31}{80} - \frac{27}{80} = \frac{4}{80} = \frac{1}{20} [/tex]

Answer:

The numbers are 12 and 32.

Step-by-step explanation:

x = One number

x - 20 = Another number

3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)

Let's solve for x, this way:

3x - (x - 20) = 84

3x - x + 20 = 84

2x = 84 - 20 (Subtracting 20 at both sides)

2x = 64

x = 64/2

x = 32 ⇒ x - 20 = 12

For the given problem, by denoting the lesser number as 'x', we can form and solve an algebraic equation to find 'x=12' and 'x+20=32', which are the lesser and the greater numbers respectively.

This problem involves the concepts of algebraic equations. Let's denote the lesser number as 'x'. Therefore, the greater number becomes 'x+20' because it is 20 more than the lesser number. The problem states that three times the greater number subtracted by the lesser number is 84. So, we can translate that into the equation: 3*(x+20) - x = 84.

Solving this equation we get: 3x + 60 - x = 84, which simplifies further to 2x + 60 = 84. Deducting 60 from both sides gives 2x = 24. Finally, dividing by 2 gives x = 12 which is the lesser number. So the greater number becomes x + 20 = 12 + 20 = 32.

Answer:

[tex] {(x + 3)}^{2} = 16[/tex]

Step-by-step explanation:

The given equation is

[tex] {x}^{2} + 6x - 7 = 0[/tex]

To find the equation that has the same solution, we complete the square.

Add the square of half the coefficient of x to both sides

[tex] {x}^{2} + 6x + {3}^{2} = {3}^{2} + 7 [/tex]

This becomes:

[tex] {x}^{2} + 6x + 9 = 9 + 7 [/tex]

Factor the first three terms to get a perfect square;

[tex]{(x + 3)}^{2} = 16[/tex]

The correct answer is C

The equation c. (x+3)^2=16 has the same solutions as the given equation x^2+6x−7=0.

The equation that has the same solutions as the given equation x^2+6x−7=0 is c. (x+3)^2=16.

Therefore, the equation (x+3)^2=16 has the same solutions as the given equation x^2+6x−7=0.

Answer:

37.70 feet

Step-by-step explanation:

-The radius of each tire is given as 6 feet.

-Distance around each tire is equivalent to the circumference of each tire.

#Circumference is calculated as:

[tex]C=\pi D=2\pi r\\\\=2\pi \times 6 \\\\=12\pi\\\\=37.70\ feet[/tex]

Hence, the distance around each tire is 37.70 feet

Answer:

D

Step-by-step explanation:

Given

C = 2πr ( isolate r by dividing both sides by 2π )

[tex]\frac{C}{2\pi }[/tex] = r → D

The circumference of a circle is defined as the distance around the circle.

The formula that represents r in terms of C is r =  C/ 2π. The correct option is Option D

From the question, we are given the formula for the circumference of the circle C as :

C = 2πr

To represent in terms of C,

2πr = C

Divide both sides by 2π

2πr/2π = C/ 2π

r =  C/ 2π

Therefore,  the formula that represents r in terms of C is r =  C/ 2π. The correct option is Option D

Camille has 42nickels and 19 quarters.

The price depends on how much amount of product one has/consumes.

Let, Camille has 'y' no. of nickels.

Therefore, she has (61-y) no. of quarters.

We know that,

1 nickel = 5cents

1 quarter =25 cents

$6.85 = 685cents (as 1 dollar = 100cents)
