Answer:
Yes I believe so is that algebra i think you set up the equation correctly I'm in a college statistic class our equations that we work with much more similar to algebra.
Step-by-step explanation:
37/11 is correct just multiply 3*11 and add four
34 + 0 + 18 + 26
= (34 + 26) + (0 + 18)
= 60 + 18
= 78
Used:
a + b = b + a - commutative property
0 + a = a - identity property
4 triangles =4*180°=720°
2 circles =2*360°=720°
Total =1440°
60÷5=12
2b/4=8 multiply both sides by 4
2b=32 divide both sides by 2
b=16
So Julia has 16 barrettes.
