Answer:
C
Step-by-step explanation:
Answer: They show numerical value. You have to make them clear.
Step-by-step explanation:
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
Answer:
x=65/n where x is 1 book and n the number of books
Step-by-step explanation:
If n is the number of books, lets say 1 book is "x", then
nx=65
x=65/n
for example
n=1 then x=65
n=2 then x=65/2
n=3 then x=65/3
