Answer:11z+20
Step-by-step explanation:3z+2-5z+18z+12-5z+6
Then u bring light terms together
16z+2+12-5z+6
11z+20
See the attached figure to better understand the problem
we know that
AM=MD
so
triangle AMD is an isosceles right triangle
therefore
its height is half its width.
Then
AB = (1/2)AD----------Equation 1
Perimeter=2*[AB+AD]=34 in ---------> AB+AD=17-------> Equation 2
I substitute 1 in 2
(1/2)AD +AD = 17
(3/2)AD=17
AD=17*2/3----------> AD=34/3-------> 11 1/3 in
AB=(1/2)AD--------> AB=(1/2)*34/3--------> AB=17/3-------> AB=5 2/3 in
the answers are
AD=11 1/3 inAB = 5 2/3 in
Answer:
240
Step-by-step explanation:
3 times 80 is 240 and 7 times 80 is 560. added together is 800. 800 is the total amount of people, so it works.
Answer:
64
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 (16) *8
A =64
5/9-2/12=?
9x8=72
5x8=40
12x6=72
2x6=12
40/72 - 12/72 = 28/72
28/4=7
72/4=18
28/72=7/18
