Triangles add up to 180°, so the answer is 67
Hey there! :D
So, we know that there are 3 z's and 3 6's.
3*z= 3z
6*3= 18
3(z+6) <== equivalent expression
3z+18 <== equivalent expression
z is by itself. It shouldn't combine. It should stay the same. 6 as a unit is separate from z.
Choices "B" and "E" are correct.
I hope this helps!

Answer:
Wouldn’t it be 13?-
Step-by-step explanation:
18 - 5 = 13
Otherwise Idk ;-;
This question is kind of tricky. To make sure, she has to sail 4 2/3 miles but she sailed 3 1/3, how far is she from her destination? Is that what you are saying? If that's what you are saying, then you have to convert both mixed fractions to improper fractions. 4 2/3 will convert to 14/3 (you multiply the whole number times the denominator (the bottom number of the fraction) plus the numerator (the number on the top)) and for 3 1/3 is going to be equal to 10/3. Now that you have both numbers in improper fractions, you can subtract. So 14/3-10/3 is going to give you an equal of 4/3, which would be 1 1/3 in a mixed fraction. YOU'RE WELCOME :D
