solve for x: 3x-3= -12
Answer:Isolate the variable by getting all terms and coefficients to the other side of the equal sign. (3x −3) = 12. Given equation. Add 3 to both sides to get −3 from the left side to the right side. 3x = 15. Divide both sides by 3 to get x by itself, which would give us an exact answer. x = 5.
Step-by-step explanation:
An odometer shows that a car has traveled 41,00$ miles by January 1, 2020. The car travels 19,000 miles each year. Write an equation that represents the number y of miles on the car’s odometer x years after 2020.
The required equation for number of miles and years for the car is given as; y = 19000x + 41000
How to represent a linear equation?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
The parameters are;
Suppose the year 2020 represents x = 0.
The distance travelled per year can be taken as the slope of the linear equation. Thus, slope = 19000.
And, the distance travelled by January 1, 2020 is 41000.
This tells us that for x = 0, y = 41000.
The linear equation in slope intercept form is given as;
y = mx + c
where;
m is slope
c is y-intercept
Substitute the corresponding values in the above equation to obtain,
y = 19000x + c
At x = 0, y = 41000
41000 = (19000 × 0) + c
c = 41000
Now, the equation can be written as,
y = 19000x + 41000

In triangle IJK , O is the intersection of the three medians . If IN = 12 find IK. please help
Since it is stated that O is the centroid (also known as the point of intersection of the three medians), the segment JN, which traverses a triangle's vertex, would have to be a median to segment IK. IK = 24
What is meant by median?When a data set's median value is used, 50% of the data points in the collection have values that are lower or equal to the median and 50% of them have values that are higher or equal to the median. When working with a small data collection, you must first count the number of data points (n) and organize them in ascending order. Sorting all of the data points and selecting the center one yields the median, or middle number (or if there are two middle numbers, taking the mean of those two numbers).Example: The number 4 is the median of the numbers 4, 1, and 7 since it is in the middle when the numbers are ordered (1, 4, 7).As a segment is divided into two congruent pieces by medians, IN = NK = 12 since IN = 12.
IK is the sum of the measure of IN and NK, so in other words:
IK = IN + NK = 12 + 12 = 24

In triangle IJK, O is the intersection of the three medians. If IN = 12 then the value of IK is 24.
What is a median?A triangle's median is a line segment that connects a vertex to the middle of the side directly across from it.
Given that, O is the intersection of the three medians. Then, the segment JN which passes through a vertex of the triangle, would have to be a median to segment IK.
A median divides the segment into two equal parts. Thus, median JN divides the segment IK into two equal parts.
Thus, IN = NK
The value of IN = 12, hence NK = 12.
The value of IK is:
IK = IN + NK = 12 + 12 = 24
Hence, in triangle IJK , O is the intersection of the three medians . If IN = 12 then the value of IK is 24.

A computer chip manufacturer had net sales of $210 million with returns equal to
of gross sales. Find gross sales rounded to the nearest million given that net sales
80
equals gross sales less returns.
The gross sales amount to $ million. (Type a whole number.)
Rounding to the nearest million, the gross sales amount to $233 million.
What do you mean by gross sales?Gross sales refer to the total amount of revenue generated from the sale of goods or services before any deductions or expenses are made. It is the total amount of money received from customers, before accounting for any discounts, returns, or other adjustments. Gross sales can also be referred to as total sales or revenue.
If net sales equal gross sales less returns, then we can write an equation:
net sales = gross sales - returns
where returns equal a certain percentage of gross sales.
$210 million = gross sales - 0.10 * gross sales
Expanding the right side of the equation:
$210 million = gross sales - 0.1 * gross sales
$210 million = (1 - 0.1) * gross sales
$210 million = 0.9 * gross sales
Dividing both sides by 0.9:
$210 million / 0.9 = 0.9 * gross sales / 0.9
$233.33 million = gross sales
Rounding to the nearest million, the gross sales amount to $233 million.

Defining a ratioIn mathematics, the term "portion" or "fraction" refers to the proportion of one number that is present in another. In a fruit platter with eight oranges and six lemons, for instance, the ratio of citrus to lemon is eight over six, meaning 8:6, which would be equivalent to the ratios of 4:3 or the decimals 1.333.

What is revenue?Revenue is money brought into a company by its business activities. There are different ways to calculate revenue, depending on the accounting method employed. Accrual accounting will include sales made on credit as revenue for goods or services delivered to the customer. Under certain rules, revenue is recognized even if payment has not yet been received.It is necessary to check the cash flow statement to assess how efficiently a company collects money owed. Cash accounting, on the other hand, will only count sales as revenue when payment is received. Cash paid to a company is known as a "receipt." It is possible to have receipts without revenue. For example, if the customer paid in advance for a service not yet rendered or undelivered goods, this activity leads to a receipt but not revenue.

What are the six trigonometric ratios?Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
From that angle (suppose its measure is θ),
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]
Given;
Height=[tex]2\sqrt{11}[/tex]
Base= 10
Hypotenuse= 12
Now,
sin M= 2[tex]\sqrt{11}[/tex]/12
=[tex]\sqrt{11}[/tex]/6
cos M= 10/12
=5/6
tan M= 2[tex]\sqrt{11}[/tex]/10
