Answer:
The missing value = 
Step-by-step explanation:
Given - Equation: ? + 59 5/8= 82 2/3
To find - Explain (in words) what you would do to find the missing value in
the equation. You do not find the missing number.
Proof -
Let the missing number = x
So, the equation becomes x + 
= 
⇒x = -
= 
= 
= 
=
⇒x =
∴ we get
The missing value =
Explanation -
Here we have given the ? with addition of number that is equation to some number.
We just have to subtract the two numbers to find the missing value , as we do above.
Answer:
x = 2
y = -3
Step-by-step explanation:
y = x - 5 -------------------(I)
x + y = -1 ----------------(II)
Substitute y = x -5 in equation (II)
x + (x - 5) = -1
x + x - 5 = -1 {Combine like terms}
2x - 5 = -1 {Add 5 to both sides}
2x = -1 + 5
2x = 4 {Divide both sides by 2}
x = 4/2
x = 2
Substitute x = 2 in equation (I)
y = 2 - 5
y = -3
The height of the person when an anthropologist finds a human femur of length will be 183.94cm.
<h3>How to calculate the height?</h3>
In order to calculate the height, the expression to use will be:
h = 1.876l + 84.512
h = 1.876(53) + 84.512
h = 99.428 + 84.512
h = 183.94
Therefore, the height is 183.94cm.

Answer:
6%
Step-by-step explanation:
The percentage is the ratio 15/250 converted to a percent. That conversion can be accomplished by multiplying the ratio by 100%. (You can do this without a calculator.)
15/250 × 100% = (1500/250)% = 6%
