Hi! i’m not sure what the question is, could you please include that?
(2x+40)+(3x+20)=180
because they are supplementary angles
therefore:
2x+3x+40+20=180
5x+60=180
5x=120
x=24
4 hours is 8 half hours
8*2 is 16 so the answer is d
Hope this helps :)
<span>There
are 8 912 butterflies on one branch.
And they estimated to have 1000 times as large.
now, find the total number of the butterflies found in their site.
=> 8 912 x 1000 (because it is stated that the number of butterflies in all
is 1 000 times as large as the given number of butterflies in a one branch.)
=> Multiply 8 912 by 1 000
=> 8 912 000
Thus, the total of butterflies in their site is approximately 8 912 000</span><span>

5+3n=8-5n should be the could answer how I solve it was adding is a plus sigh=n and less than is a minus sign
