Answer:
x=0
Step-by-step explanation:
-3 -1
---------- = -----------
x+3 x+1
We can solve using cross products
-3 *(x+1) = -1(x+3)
-3x -3 = -1x -3
Add 3x to each side
-3x -3 +3x = -x -3 +3x
-3 = 2x -3
Add 3 to each side
-3+3 = 2x-3+3
0 =2x
Divide by 2
0/2 =2x/2
0=x

Answer
7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds
Answer:
m(n) = 60000
Amount = 60000/n
Step-by-step explanation:
Given
Budget = 60000
Solving (a) Represent as a function mn
To do this simple substitute m(n) for Budget.
This gives;
m(n) = 60000
Solving (b) Amount each committee will receive.
Since the amount will be shared evenly.
Amount = m(n)/n
Substitute 60000 for m(n)
Amount = 60000/n
C . set of all integers and set of rational numbers
