Answer:
x = 6
Step-by-step explanation:
Using the rules of logarithms
• log x - log y ⇔ log ( )
• x = n ⇔ x =
Given
log(5x) - log(x - 3) = 1
log ( ) = 1, then
= = 10 ( cross- multiply )
10(x - 3) = 5x
10x - 30 = 5x ( subtract 5x from both sides )
5x - 30 = 0 ( add 30 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Remove 10 quarts from blue
5 parts blue 3 parts yellow
5 parts blue 3 parts yellow
5 parts blue 3 parts yellos
total: 15 parts blue
9 parts yellow
remove the remaining 10 parts blue, since you do not have any more yellow
CD = sqrt (6^2 - 5^2)
CD = sqrt(36 - 25)
CD = sqrt(11)
CD = 3.3
answer
D. 3.3
Answer:
10
Step-by-step explanation:
10 apple pies = 4 pounds of apples
Divide both sides by 10
10/10 apple pie = 4/10 pounds of apples
1 apple pie = 2/5 pounds of apples
Multiply both sides by 25
25 apple pies = 2/5 * 25
= 10 pounds of apples
Therefore 25 apple pies will be produced using 10 pounds of apples
