Answer:

x is equal to 5

Step-by-step explanation:

78 = 12x + 18

12x + 18 = 78

12x = 78 - 18

12x = 60

x = 60/12

x = 5

btw i made 78 equal to 12x + 18 because it is parallel. they both equal the same (i think its called parallel. idrk)

X is equal to 5

78=12x+18

12x=78-18

12x=60

X=60/12

X=5

Answer:

Answer is 62

Step-by-step explanation:

here is my work if this is any help

Any point on the outside edge of a circle from the center of a circle would be the radius, which would be the same distance all the way around. The outer edge of the larger circle goes through the dot labeled B, which is the center of the smaller circle, therefore any distance from B to the outer edge would be the same.

The length of segment BD is the same as the length of segment AB because any distance from B to the outer edge would be the same.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Any point on the outside edge of a circle from the center of a circle will be the radius, which would be the same distance all the way around.

The outer edge of the larger circle goes through the dot labeled B, which means the center of the smaller circle.

Therefore any distance from B to the outer edge would be the same.

Answer:

C. f(n+1) = 1.05f(n)

Step-by-step explanation:

correct on edge

f(n + 1) = 1.05f(n) can be used to determine the total amount of money earned in any year based on the amount earned in the previous year.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

Here, we have,

Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.

100, 105, 110.25, ...

hence, f(n + 1) = 1.05f(n) can be used to determine the total amount of money earned in any year based on the amount earned in the previous year.

C ≈ 31.4 units

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ) , then

C = 2π × 5 = 10π ≈ 31.4 units ( to the nearest tenth )

Answer:

Area of Mrs. Margarita's garden = 1188.39 m²

Step-by-step explanation:

Using the most basic formula to solve this question i.e. Area of circle. We know that: Area of of circle = πr². But in problem we are provided with a half shaped circle. Means we need to use the half of the area of circle or you can say semi-circle.

Now, read the question again. Mrs. Margarita has a garden shaped like a half-shaped circle with a diameter of 55 m. Given diameter is 55 m and we know that radius is half of the diameter. So, radius is 55/2 m. Rest what we need to do is substitute the values and do the rest calculations.

Let's dive in!

= 1/2 × 22/7 × 55/2 × 55/2

= 11/7 × 55/2 × 55/2

= 33275/28

Here, we are given with ;

[tex]{:\implies \quad \sf (3x^{2}-7x)-(4x^{2}+6x)}[/tex]

Opening parentheses will yield;

[tex]{:\implies \quad \sf 3x^{2}-7x-4x^{2}-6x}[/tex]

Collecting like terms ;

[tex]{:\implies \quad \sf (3x^{2}-4x^{2})+(-7x-6x)}[/tex]

[tex]{:\implies \quad \sf -x^{2}-13x}[/tex]

Hence, the required answer is - x² - 13x

Answer:

[tex](3 {x}^{2} - 7x) - (4 {x}^{2} + 6x) \\ \longrightarrow \: \: 3 {x}^{2} - 7x - 4 {x}^{2} - 6x \\ \longrightarrow \: \: {3x}^{2} - {4x}^{2} - 7x - 6x \\ \longrightarrow \: \: - {x}^{2} - 13x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

Answer:

[tex]\sf x = 7.8[/tex]

explanation:

[tex]\sf a^2 + b^2 = c^2[/tex]

[tex]\hookrightarrow \sf 9.5^2 + x^2 = 12.3^2[/tex]

[tex]\hookrightarrow \sf x^2 = 12.3^2 - 9.5^2[/tex]

[tex]\sf \hookrightarrow x^2 = 151.29 - 90.25[/tex]

[tex]\hookrightarrow \sf x^2 = 61.04[/tex]

[tex]\hookrightarrow \sf x = \sqrt{61.04}[/tex]

[tex]\hookrightarrow \sf x = 7.8[/tex]

Answer:

p = 7

Step-by-step explanation:

6p - 10 and 32 are vertically opposite angles and are congruent , then

6p - 10 = 32 ( add 10 to both sides )

6p = 42 ( divide both sides by 6 )

p = 7

The expression that is equivalent to the expression [(6c² + 3c)/(-4c + 2)] ÷ [(2c + 1)/(4c - 2)] is; -3c

Simplification of fractions is the process of reducing fractions that involves making the fraction as simple as feasible.

We achieve this by dividing the numerator and denominator by the greatest integer that divides perfectly into both numbers.

The given expression is;

[tex]\frac{[(6c^2 + 3c)(-4c + 2)] }{[(2c + 1)/(4c - 2)]}[/tex]

On Simplifying the fraction equation by factorization we obtained ;

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

[tex]\frac{[3c(2c + 1) }{(-2(2c - 1))] \times [(2(2c - 1)/(2c + 1)]}[/tex]

[tex]-3c[/tex]

Hence he expression that is equivalent to the expression [(6c² + 3c)/(-4c + 2)] ÷ [(2c + 1)/(4c - 2)] is; -3c

Answer:

Step-by-step explanation:

let the number of members in the club be N

The first day the members paid

$30 for transportation plus $20 per ticket to the planetarium.

cost= 30+20N

The second day the members paid

$95 for transportation plus $17 per ticket to theGeology museum.

cost= 95+17N

total cost is

T= 30+20N+ 95+17N

T=30+95+20N+17N

T=125+37N

An expression to represent the total cost and dollars for two days for the N members of the club is

T=125+37N
