Answer:
It is b. ACB
Step-by-step explanation:
If draw a triangle, you would give the longest side to BC, because their angles equal 10
And you would give AC the shortest side of the triagle because their angles equal 7
And AB the last side because it is in between the other sides
Since AC have the smallest angle, they would have the smaller numbers
then that leaves B as the biggist number
The answer is 115 dont worry i took the test alr
Answer:
180 tacos and 100 burritos was sold
Step-by-step explanation:
Let <em>t</em><em> </em>represent tacos
Let <em>b</em><em> </em>represent burritos
<em>t</em><em> </em>+ <em>b</em><em> </em>= 280
<em>2t</em><em> </em>+ <em>3b</em><em> </em><em>=</em><em> </em><em>660</em>
From t + b = 280,
t = 280 - b
Substitute t = 280 - b in 2t + 3b = 660
2t + 3b = 660
2(280 - b) + 3b = 660
560 - 2b + 3b = 660
560 + b = 660
b = 660 - 560
b = 100
Substitute b = 100 in t + b = 280
t + b = 280
t + 100 = 280
t = 280 - 100
t = 180
t = tacos = 180
b = burritos = 100
Idk figure it out.. sorry
