What is the x value of 10=-x-8-6
gulaghasi [49]
10=-x-8-6
10=-x-14
Add x to each side
10+x=-x-14+x
10+x=-14
Subtract 10 to each side
10+x-10=-14-10
x=-24
Check:
10=-x-8-6
Substitute x with -24
10=-(-24)-8-6
10=24-8-6
10=16-6
10=10. As a result, x=-24. Hope it help!

Use the elimination method to solve the system of equations. Choose the
Yakvenalex [24]

Answer:

(2, 7) is the correct ordered pair.

Step-by-step explanation:

5x + 3y = 31

2x + 3y = 25   Subtract to eliminate the y variable:

3x = 6

x = 6/3

x = 2.

Substitute x = 2 in the first equation:

5*2 + 3y = 31

3y = 31-10 = 21

y = 21/3

y = 7.

Check the result by substituting for x and y in the second equation:

2(2) + 3(7) = 25

4 + 21 = 25

25 = 25.

Use the given equivalents, along with dimensional analysis, to convert the given unit to the unit indicated.
defon

By using the dimensional analysis 580 lb = 263.084 kg.

What is dimensional analysis?

Dimensional analysis, which is used in both engineering and science, examines the links between various physical quantities by determining their foundational quantities and units of measurement and then following these dimensions while computations or comparisons are made.

A technique for analysis that, in the absence of sufficient data to establish accurate equations, expresses physical quantities in terms of their fundamental dimensions.

We have to convert 580 lb into kg along with the dimensional analysis.

Since, 1 pound (lb) is equal to 0.45359237 kilograms (kg).

So,

580 lb = (0.4535927) x 580

580 lb = 263.0835746

580 lb = 263.084 kg

Hence, along with the dimensional analysis 580 lb = 263.084 kg.
