Answer:

$\boxed{\sf x=2}$

Step-by-step explanation:

$\sf 19 =5+7x$

First, let's swap sides so that all variable terms are on the left hand side.

$\sf 5+7x=19$

Subtract 5 from both sides:

$\sf 7x=19-5$

Subtract 5 from 19:

$\sf 7x=14$

Divide both sides by 7:

$\sf \cfrac{7x}{7} =\cfrac{14}{7}$

$\sf x=2$

The Sweet water High School Project Graduation committee is hosting a dinner-and-dance fundraiser at the Sweet water Community C

yan [13]

Answer:

<h2> 105 tickets</h2>

Step-by-step explanation:

To solve this problem we need to model an equation to represent the situation first.

the goal is to archive $7500 in the even, bearing in mind that there is a cost of $375 fee for rent, we need to put this amount into consideration

let the number of tickets be x

75x-375>=7500--------1

Equation 1 above is a good model for the equation

we can now solve for x to determine the number of tickets to be sold to archive the aim

75x-375>=7500--------1

75x>=7500+375

75x>=7875

divide both sides by 75 we have

x>=7875/75

x>=105 tickets

so they must sell a total of 105 tickets and above to meet the target of $7500 with the rent inclusive

Using the standard form of the equation in question 1, what are the length of the radius and the coordinates of the center for t

shusha [124]

The coordinates of the center is at (1, 0) and the length of the radius is 4 units.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The standard form of a circle is:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius.

The coordinates of the center is at (1, 0) and the length of the radius is 4 units.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-6, -5)

Point (2, 0)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(2+6)^2+(0+5)^2}$
Add: $\displaystyle d = \sqrt{(8)^2+(5)^2}$
Exponents: $\displaystyle d = \sqrt{64+25}$
Add: $\displaystyle d = \sqrt{89}$
