Okay so this is how you solve this step by step.

2log7(5)+log7(x)=log7(100)

Subtract 2log7(5) from both sides

log7(x)=log7(100)-2log7(5)

Simplify log7(100)-2log7(5)

log7(x)=2log7(2)

Apply log rule: alogc(b)=logc(b^a)

log7(x)=log7(4)

x=4. <----Answer

I hope this helps.

Nestor works at a garden center where he posts plants. It takes him 2 1/2 hours to pot 15 plants. How many plants can Nestor pot

guapka [62]

Answer:

Nestor can pot 6 plants in 1 hour.

Step-by-step explanation:

first lets convert 2 1/2 hours in mixed fraction form for better calculation

2 1/2 hours = (2*2 + 1)/2 = 5/2 hours

no of plants pot in 5/2 hours = 15

to find no. of plants pot in 1 hours lets

divide both side by 5/2

no of plants pot in 5/2/(5/2) hours = 15/(5/2) = 15*2/5 = 6

no. of plants pot in 1 hour = 6

Thus, Nestor can pot 6 plants in 1 hour.
