Answer:
x= 3
Step-by-step explanation:
Given data
Ratio= 5:2:x
Combined ratio= 5+2+x
= 7+x
Total amount of money= $15000
Let us apply the part to all method
Hence for Matthew whose share = $7500
5/7+x= 7500/15000
Cross multiply we have
7500*(7+x)= 15000*5
52500+7500x= 75000
Collect like terms we have
7500x= 75000-52500
7500x=22500
x= 22500/7500
x=3
Hence the value of x= 3
Answer:

Answer:
The domain of f is equal to x = log8 x.
Step-by-step explanation:
(-3,5)(6,-1)
slope = (-1 - 5) / (6 - (-3) = -6/9 which reduces to - 2/3 <=
