Answer:
Option B
Step-by-step explanation:
The question can be solved without observing the masses and calculating them.
How?
- Periodic table law states that masses get increased in group and get decreased in period.
- Hydrogen is the 1st element so it has least mass.
Now
Only option B and D has Hydrogen at first.
Now coming to last elements Carbon and Gold
Gold is heavier as per periodic table.
So option B is correct
Answer:
d
Step-by-step explanation:
the slope is change in y over change is x and as y goes down 5 x goes up 3
so -5/3 is the slope
hope this helps :)
Answer:
Step-by-step explanation:
21 feet below is written as -21
9 feet up is written as +9
So we have -21 + 9 = -12 or 12 feet below sea level
If the sum of an integer and 7 more than the next consecutive integer is 66 then the integers are 29 and 30.
Given that the sum of an integer and 7 more than the next consecutive integer is 66.
Integer is a number that is written without a fraction component. It can be positive as well as negative.
let the first integer be x.
Consecutive integer will be x+1.
Sum of integer and 7 more than the next consecutive integer is 66.
Sum according to the given information=x+x+1+7
=2x+8
2x+8=66
2x=66-8
2x=58
x=58/2
x=29
Next integer=29+1-30.
Hence if the sum of an integer and 7 more than the next consecutive integer is 66 then the integers are 29 and 30.
