Answer:
the answer must be A
Step-by-step explanation:
To solve all of these, you put the expressions you've been given into an equation that equals whatever number the sheet tells you is the sum of the angle measures. Then you just substitute it in to find the angle measures. I'll do the first one for you but tell me if you want me to do the rest:
2k + k + 45 = 180
3k + 45 = 180
- 45
3k = 135
÷ 3
k = 45°
45 × 2 (2k) = 90
Again let me know if you want the answers and working to the other two :)
Answer:
15 because 32 - 17 = 15
Step-by-step explanation:
Answer:
56
Step-by-step explanation:
16 x 3 = 48
Half of 16 is 8
48 + 8 = 56
Each train carried 64141 kg of flour and each truck carried 9163 kg of flour.
Step-by-step explanation:
Let the no. of kg of flour carried by each train be 'a'
Let the no. of kg of flour carried by each truck be 'b'
Total flour = 403172 kg
No. Of trains = 5
No. of trucks = 9
a = 7(b)
5a + 9b = 403172
5(7b) + 9b = 403172
35b + 9b = 403172
44b = 403172
b = 403172/44
b = 9163
Each truck carried 9163 kg of flour.
a = 7b
a = 7(9163)
a = 64141
Each train carried 64141 kg of flour.
