Answer: Let the numbers be x and y.
x+y = 20 …(1)
x-y = 10 …(2)
Add (1) and (2)
2x = 30, or x = 15, and so y = 5.
The product of the two numbers = xy = 15*5 = 75.
Step-by-step explanation:
Answer:
3.245
2.22+1.51+1.86+2.06+3.48+4.57+3.27+5.40+5.45+4.34+2.64+2.14 then divide by twelve because that is the number of months :))))
p= mgh/t
= 70×10×4/7=400J/sec
2% decrease= 0.98
3% decrease = 0.97
c=(6x+3y)-8
