Answer:
1107 feets below sea level
Step-by-step explanation:
Given that :
Initial elevation of submarine = 984.6 feets below sea level
Depth of dive from initial elevation = 122.4 feets below sea level
The elevation after the dive :
Initial elevation + depth of dive
984.6 + 122.4
= 1107 feets below sea level
Answer:
-2.5 = x
Step-by-step explanation:
Multiply by what's in the parentheses by 2.
6x - 1 = 4x - 6
Add 6 to both sides of equation.
6x + 5 = 4x
Subtract 6x from both sides.
5 = -2x
Divide both sides by -2.
-2.5 = x
Answer:
A is correct.
Step-by-step explanation:
From the second sentence , we can deduce that the total number of problems is 29.
Now, x represents the number of problems that award 5 marks, while y represents the number of problems that award 2 marks.
Hence x + y = 29.
There are a total of 100 marks. This mean each x has a mark of 5, so total x marks equal 5x. Also, each y has a mark of 2. total y marks equal 2y. Since total marks equal 100. This mean 5x + 2y = 100 which gives our second equation.
This shows A is correct.
There is an infinite amount of numbers in-between 34.65 and 34.66 for example, 34.652 or 34.6534
