Answer: x = 10 y=20
Step-by-step explanation:
You can answer this question by plugging in each equation:
2x=y, x+y=30. Let us plug y as 2x in the second equation x+y=30
x+2x= 30
3x= 30
x=10
After we found x we can then find y by plugging the 10 for x.
2(10) = y
y =20
or you could plug in the other equation
10+y=30
subtract 10 from 30 and we get 20
to double check we can plug in both numbers
2(10) = 20 which is correct
and 10 + 20 = 30 which is correct
Answer:
64°
Step-by-step explanation:
angle 1+40°=104°(sum of two non adjacent interior angles is equal to opposite exterior angle)
angle 1=104°-40°
angle 1=64°
Because all three angles add up to 180 (a line) it would be 65+65, or 130 degrees. Then subtract 130 from 180. your missing angle is 50 degrees
Answer:
Step-by-step explanation:
The proccedure shown in the problem is applied to solve for x and calculate its value.
One of the equations shown in the problem is:
To solve for x you must_
- Add 6 to both sides of the equations:
- Then you must divide by -3:
Then the answer is:
