What is the purpose of simultaneous equations?

Mathematics

sveta [45]3 years ago
5 0

Answer:

a set of two or more equations, each containing two or more variables whose values can simultaneously satisfy both or all the equations in the set, the number of variables being equal to or less than the number of equations in the set.

Step-by-step explanation:

It works because of two properties of equations: Multiplying (or dividing) the expression on each side by the same number does not alter the equation. Adding two equations produces another valid equation: e.g. 2x = x + 10 (x = 10) and x − 3 = 7 (x also = 10).

In the year 2000,there were 8.7 deaths per 1000 reidents in the United States.If there were 281,421,906 residents in the U.S.dur
bekas [8.4K]
\frac{deaths}{residents} \: \frac{8.7}{1000} \: \frac{x}{281421906}
Find the "difference" between the residents but division.

281421906/1000 = 281421.906
You always have to do the same to the top
8.7×281421.906 = 2,448,370.5822

There were 2,448,370.5822 deaths

A company buys pens at the rate of $5.50 per box for the first 10 boxes, $4.50 per box for the next 10 boxes, and $3.50 per box
marusya05 [52]

So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.

So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.
