Answer:
280
Step-by-step explanation:
Answer: A. 70
Step-by-step explanation:
95 + 90 + 85 + 80 + 70 = 420, then divide that by 5 equals 84
Answer:
B. .002, .03, .6, .9
Step-by-step explanation:
.002 is .002
.03 is .030
.6 is .60
And, .9 is .90
So in conclusion, least to greatest would be .002 , .030 , .60 , then last but not least .90. The option that best matches this is B!
Whenever a problem says "one number" and "another number" we can substitute x and y. for this we have x=2y+1 and xy=1. since we know the value of x (2y+1) we can substitute it for the other equation to get (2y+1)y=10. simplify to get 2y^2+y=10. from here you can do a few methods to solve this, but the simplest in my opinion is by factoring.
In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.
this means our two numbers are 5 and 2
