Answer:
j=10-3k
Step-by-step explanation:
here you go...i hope it's correct
A : 1.01
I don’t have a explanations for it tho sorry ...
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
3 cans!!!
5x6= 30 (divided by 2= 15)
5x6=30 (divided by 2 = 15)
10x18= 180
180+30= 210
3 cans!!
Setting up and solving an equation of ratios is one of the fastest ways in which to solve this kind of probelm.
183 miles 3 hrs
-------------- = ------------
x 11 hrs
Do the math. You'll find that x = 671 miles.
