Answer:
71°
Step-by-step explanation:
3x° + (x - 11)° + (2x - 55)° = 360°
3x + x - 11 + 2x - 55 = 360°
6x - 66 = 360°
6x = 360° + 66°
6x = 426°
x = 71°
The mixed number of it would be 5 42/45 if you're looking for the mixed number (to find the mixed number divide 267 and 45)
Answer:
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Step-by-step explanation:
Let the weight of pineapple be x grams and weight of orange by y grams.
Now, weight of a pineapple = 7 (weight of an orange)
∴ x = 7y
Also, x = y + 870 (∵ pineapple weighs 870 more than pineapple)
Substituting the value of x in above equation,
7y = y + 870
7y - y = 870
6y = 870
y = 870/6 = 145
Weight of an orange = 145 grams
Weight of pineapple = 7 × 145 = 1015 grams
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Answer:
r=-2
Step-by-step explanation:
difference in y/difference in x =slope
-r-8/1-2=-9
-r-8=-9*-1
-r=10+8
r=-2
