how do you solve a system of equations approximately given tables without using equations or graphing?

solong [7]3 years ago

system of equations means that we have a given number of equations with the same solutions.

If you only have tables, this means that you need to have one table for each equation:

For example, if you are working only with two variables, x and y, in those tables you can see the pints (x, y) that belong to each equation.

Now, a point (x, y) will be a solution of the system of equations only if it belongs to the data table for each equation

This would mean that if you graph those data sets, the graphs will intersect at the point (x, y) that belongs to all the tables of data.

another way may be using the data in the tables to construct the equations, but you said that you only want to use the tables, so this method can be discarded.

The equation is 12m+12=15-1
Fudgin [204]

Answer:

1/6

Step-by-step explanation:

Solve-

Subtract the numbers:

12m+12=15 - 1

12m+12 = 14

Subtract 12 form both sides of the equation:

12m+12= 14

12m+12-12 =14-12

Simplify:

Subtract 1: 12m+12-12=14-12

12m=14-12

then 2; 12m=14-12

12m=2

Divide both sides of the equation by the same term:

12m=2

12m/12=2/12

Simplify again:

Cancel out the terms:

12m/12=2/12

m=2/12

Divide the numbers:

m=2/12

m=1/6

Soulution= 1/6

An electronics store received two shipments of radios. Of the 250 radios in the first shipment, exactly 6% were damaged. In the
nataly862011 [7]

Answer:

Total number of not damaged = 451

C. 451

Step-by-step explanation:

In the first shipment, 6% of the 250 radios where damaged.

Number of damaged= 6/100 * 250

Number of damaged= 6*2.5

Number of damaged= 15 radios.

Number of not damaged= 250-15

Number of not damaged = 235 radios

In the second shipment, 4% of the radios were damaged

Let the number of second shipment= y

0.04 of y where damaged

Total number of radio damaged= 24

15 + 0.04y = 24

0.04y= 24-15

0.04y = 9

Y= 9/0.04

Y= 225

Number of radio in the second shipment= 225

Number of damaged in the second shipment= 0.04*225

Number of damaged in the second shipment= 9

Number of not damaged in the second shipment= 225-9

Number of damaged in the second shipment= 216

Total number of not damaged

= 235+216

= 451

Total number of not damaged= 451
