Answer:
8, 5, 3 are the numbers.
Step-by-step explanation:
Let the three numbers are x, y , and z.
out of which x is the largest and z is the smallest number.
Sum of three numbers is 16.
x + y + z = 16------(1)
The largest number is equal to the sum of the other two.
x = y + z --------(2)
3 times the smallest number is 1 more than the largest.
3z = x + 1 ---------(3)
Now we put the value of x from equation (2) to equation (1)
x + x = 16
2x = 16
x = 8
By putting x = 8 in equation (3)
3z = 8 + 1
3z = 9
z = 3
Now we put the values of x and z in equation (2)
8 = y + 3
y = 8 - 3
y = 5
Therefore, the numbers are 8, 5, 3.
x = 8
Z = 7/3
y = 17/3
Answer: 14000 decigrams

Answer:
14000 decigrams
Step-by-step explanation:
p = d – 1
p = d – 2
p = d + 1
d = 2p
d = 2p – 1
d = 2p
d = 2p + 1
The pair of equations that models the relationship between p and d are expressed as: p = d + 2, and p = d - 1.
An equation is used to represent a situation using variables (letters) and figures.
"p is 2 more than d" can be expressed as: p = d + 2.
Also, we can represent the statement, "p is 1 less than d" as: p = d - 1.
Therefore, the pair of equations would be: p = d + 2, and p = d - 1.

Compound inequality
Answer:
Area of a circle = Aπr²
*You multiply the area by pi and then by the square of the radius.
**If you are given the diameter instead of the area then just divide it by 2 and substitute it in the expression.
***If you are given the circumference then: A = C²/ 4π
