Well first we want to divide 1 by 3 , which is 0.3 , Now we need to divide 4 by 5 which is 0.8 .
We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.
Now lets add 7 and 1.1 all together , which is 8.1.

Answer:
D. 
Step-by-step explanation:

Since we are multiplying an exponential number to a fraction the answer is going to be

Hope this helps ❤❤❤ ;)
All the choices are in the slope-intercept form where,
y=mx+b
so, the number before the x is the slope. The given slope is -34. We just have to look for the -34 number before the x. So mong the choices, it is the letter a choice that has the slope -34. So the answer is A.
Step-by-step explanation:
equate the two equations
3x4=5x-10
12=5x-10
22=5x
x=4.4
