Answer:
x =
- a
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2T = n(a + x)d
Since n and d are both multipliers, divide both sides by nd
= a + x
Isolate x by subtracting a from both sides, hence
x =
- a
Answer:
Labour working and paid on hourly basis.
Step-by-step explanation:
Let us imagine a situation where a person is getting paid hourly basis. The rate of payment per hour is $5. Hence , if the number of hours for which he or she works is represented by t, the total amount he earned ,say represented by y, will be y=5t.
Where t is the independent variables and y is the dependent variable.
Every triangle equals 180 degrees, and we're trying to find the angle of DBA. So, we can identify DAB as a 90 degree angle to start. Then we can identify that ACB = ADB, meaning ADB is 30 degrees. With that information, we have this equation:
DBA = 180 - 90 - 30
DBA = 60
