Answer:
It takes 6 hours for both to reach an equal paid.
Step-by-step explanation:
You have to form an expressions in terms of x where x determine the number of hours :
Option 1,
$(30 + 9x)
Option 2,
$(14x)
Next, you have to compare it since they want to find out how many hours they work until they reach the same amount :
30 + 9x = 14x
30 = 14x - 9x
30 = 5x
5x = 30
x = 30÷5
x = 6
Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)
Answer: 
Step-by-step explanation:
Having the following equation given in the exercise:
You can solve for "a" following this procedure:
1. You can apply the Subtraction property of equality and subtract 
from both sides of the equation:
2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:
3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:
1/5 + 3/10
= 2/10 + 3/10
= 5/10
= 1/2
