One integer added to another integer gives a sum of 2. When the larger integer is subtracted from the smaller integer, the diffe
alexandr402 [8]

For this case we have the following variables, let:

x: The greater integer

y: The minor integer

We have to:

x + y = 2 (1)\\y-x = -14 (2)

Thus, we have a system of two equations with two unknowns. To solve, we follow the steps below:

Step 1:

We add both equations:

x + y + y-x = 2-14\\2y = -12

y = \frac {-12} {2}\\y = -6

Thus, the smallest integer is y = -6

Step 2:

We substitute "y" in any of the equations and clear x:

x + y = 2\\x + (- 6) = 2\\x-6 = 2\\x = 2 + 6\\x = 8

Thus, the largest integer is x = 8

So:

8 + (- 6) = 8-6 = 2\\-6-8 = -14

Anwer:

Integer minor, y = -6

Integer greater,x = 8

Since angles XYZ and RYS are vertical angles, they must have the same measure. Consequently,
6x + 10 = 5x + 30
From there, solve for x:
x + 10 = 30 \\ x = 20

How do i find angles in a circle
NNADVOKAT [17]

Answer:

the central angle is essentially the arc length multiplied by 360, the degrees of a full circle, divided by the circumference of the circle. As you can see, the arc length is simply the circumference of a circle (2πR) multiplied by the ratio of the arc angle to the full 360 angle of a circle.
