We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
Answer:
-5.4c
Step-by-step explanation:
We're combining two "like" terms here.
It may make the problem easier to visualize if we write one of these terms over the other, as follows:
-2.6c
- 2.8c
----------
Adding, we get:
-2.6c
- 2.8c
----------
- 5.4c (answer)
Jayana is trying to run 30 miles by the end of the months.
30% / 100% = 9 / x
9 * 100 = 900
900 / 30 = 30 miles
Answer:
Maria is 10, Floyd is 8, and Karen is 5.
Step-by-step explanation:
Having said that Maria's age was the smallest two-digit number, that's ten. (10). If Floyd is 2 years younger then 10-2=8. Karen is 3 years younger, so she would be 8-3=5.
