78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
C
explanation:
6(1)-39=-33
6(2)-39=-27
So the angle A on the first diamond corresponds with angle Q, angle B with angle S, angle C with angle R, and angle D with angle P. So if angle D correspond (equals) angle P then x+34=97 and if angle R corresponds with C then 3y-13=83. From there just do some basic algebra to find the x and y values.
Answer:
Give Branliest PLz
Answer is 15
Step-by-step explanation:
Half of 40 is 20 cause 40/2=20
Five less than 20 is 20-5 which= 15
So ur answer is 15
