2 x (multiplication sign, not an x) (x+7) or 2(x+7)
Answer: x=15
Explanation: you can set 2x+100 = 5x+55 because they are corresponding interior angles.
Work:
2x+100 = 5x+55
2x+100-5x = 55
2x-5x = 55-100
-3x = -45
divide by -3 to cancel the negative and get x by itself
x = 15

Answer:
0.06
Step-by-step explanation:
0.42 ounces is enough for 14 plants. After watering 12 plants, there will be enough plant food left over for 2 plants. Write a proportion:

Cross multiply:
14x = 0.84
Solve:
x = 0.06
