Y=2x+0.5
4.5=2x+0.5
4.5-0.5=4
4=2x
4÷2=2
x=2
so
Answer:
x=7
Step-by-step explanation:
If one of the angles is a right angle, then it equals 90 degrees. Since the other angle is 33 degrees and all triangles equal 180 degrees, then that means that the remaining angle must equal 57. Since the angle that equals 57 degrees is represented by the expression 6x+15, then 57=6x+15 and now all that's left is to simplify:
Hope this helps :)
Answer: 10
Step-by-step explanation:
Given : The American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cancer.
Then, the proportion of death will be :_
Now, If there are 200 students in a class, then the expected number of persons die from lung cancer :-
Hence, we expect the number of persons die from lung cancer =10
I think it’s the fourth one
