What is the solution to the system of linear equations? {2x+4y=38 10x+3y=105

natali 33 [55]

This is the concept of simultaneous equations, the question requires us to solve the system of equations given by:
2x+4y=38
10x+3y=105
from the top equation;
2x=38-4y
dividing through by 2 we get:
x=19-2y......(*)
substituting (*) in the second equation we get:
10x+3y=105
10(19-2y)+3y=105
190-20y+3y=105
collecting like terms we get:
-20y+3y=105-190
-17y=-85
dividing both sides by -17 we get:
(-17y)/(-17)=(-85)/(-17)
y=5
thus
x=19-2y
x=19-2*5
x=19-10
x=9
thus
x=9 and y=5

12<7+n I am giving everybody 20 points

VashaNatasha [74]

Subtract 7 from both sides

12 - 7 < n

Simplify 12 - 7 to 5

5 < n

Switch sides

n > 5

Two objects in outer space drift apart at an average rate of 25 kilometers every year. if the objects continue to drift apart fr

arlik [135]

The distance between the two objects in 10 years will be 250 kilometers.

What is Distance?

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

We are given:

The rate at which two objects drift apart in 1 year = 25 km

To calculate the distance between the two objects in 10 years, we apply unitary method:

The distance, the two objects has drifted apart in 1 year is 25 km

So, the distance, the two objects has been drifted apart in 10 years, will be = $\frac{25}{1} * 1 = 250 Km$

Therefore, the distance between the two objects in 10 years will be 250 kilometers.
