All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
Answer:
7s
Step-by-step explanation:
17s-10=3(2s+1)
17s-10 = 7s
2s+1=3s
7s+3s=10
10-3=7s

Answer:
D
Step-by-step explanation:
Suppose she only fills her big pots. The number of big pots filled is 120÷12=10. So the y-intercept is (0,10).
Now suppose she only fills her small pots. The number of small pots filled is 120÷5=24. So the x-intercept is (24,0)
