Answer:
-Z-18
Step-by-step explanation:
-2z+12-30+z
=-z-18
A regular polygon<span> is equilateral (it has equal sides) and equiangular (it has equal angles). To find the </span>area<span> of a regular </span>polygon<span>, you use an apothem — a segment that joins the </span>polygon's<span> center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).</span>
18 miles are 2/3 of the total length home so 1/3 is 18/2=9 miles
the total length of his drive is 3(1/3) = 3·9= 27 miles
answer is 27 miles
X+y+z=t
simple..
there are no other numbers that we have to follow like (1/2x or 3/4y) so it is just all together=t. the x, y, z will equal t because t is the total number of students taking three languages. And that number should be equivalent to x,y,z combined.
otherwise?? i d k<span />
Answer: C x=20+4+4 That’s the answer
Step-by-step explanation: Commutative property:
For multiplication: x ∙ y = y ∙ x
Example 1:
For addition: x + y = y + x
Example 2:
Notice that numbers don’t commute under the operation of subtraction
