Answer:
29 × 51 inches
Step-by-step explanation:
If the scale is ...

Answer:
The answer is B.) s=d/t
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)
Estimate of 2854 = 3000
so 3000 times 9 = 27000
