Take the mixed number in the parentheses and you get 50/3, and when you divide it by 2, you get 25/3. There might have been a problem in this question, but if I were you I would go with 8.
Answer:
∠ C = ∠BCD = 30°
Step-by-step explanation:
∠ EDF = ∠GFC = 110° [ corresponding angles ]
Now consider triangle BCF
∠FBC + ∠ABC = 180° [ straight line angle ]
∠FBC + 100° = 180°
∠FBC = 180 - 100 = 80°
∠BFC + ∠GFC = 180° [ straight line angle ]
∠BFC + 110° = 180°
∠BFC = 180 - 110 = 70°
Sum of angles of triangle is 180°
Therefore , in triangle BCF
That is ,
∠F + ∠B + ∠ C = 180°
70° + 80° + ∠C = 180°
∠C = 180 - 150 = 30°
Answer: -7 -2
Step-by-step explanation:-7 + -2=9 -7×-2=14
The answer would be 1,020 minutes every 30 days

is the proportion of tires that are defective so

so we would expect around 1600 tires to be defective
