One way to solve the system is to substitute a variable.

Explanation:

One approach to solve an equation is by substitution of one variable. Right now, a condition for one factor, at that point substitute that arrangement in the other condition, and explain. All value(s) of the variable(s) that fulfills a condition, disparity, arrangement of conditions, or arrangement of imbalances.

The technique for tackling "by substitution" works by settling one of the conditions (you pick which one) for one of the factors (you pick which one), and afterward stopping this go into the other condition, "subbing" for the picked variable and fathoming for the other. At that point you back-explain for the principal variable.

Plz help one question

Vladimir [108]

z° = 80° (Being corresponding angles)

y° + 80° = 180° (Being linear pair of angles)

=> y° = 180° - 80°

=> y° = 100°

x° = y° (Being interior opposite angles)

=> x° = 100°

Find mean, median and mode of 140, 130, 90, 80, 60, 50, 30, 20, 10, 0

Alecsey [184]

For the mean you would have to add up all the numbers up and divide by the amount of numbers. For your problem you would get 610/10= 61.

For the median you would arrange all the numbers in order from least to greatest and cancel one from the left and one from the right each time. Since there is no middle number, the closest would be 50 and 60. Thus you you add 50+60 and get 110 and then divide by 2 giving you 55.

For the mode, there is no mode because none of the numbers repeat more than once.

I hope this clarifies your doubt. :)

help finding the perimter of 78.4 inches whats the length of each side and show me how to work the promblem

LuckyWell [14K]

A square has four even sides and the perimeter is equal to the sum of all of the sides.
$P=s+s+s+s=4s$
So we can evaluate the equation for P and then solve for s.
$78.4=4s \\ \frac{78.4}{4} =s \\ s=19.6in$

Find the measure of angle2 A. 90 B. 50 C. 60 D. 30

galina1969 [7]

I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense
