Answer:
Andy basically has two stickers
Number of plants = 5
Amount of soil present for 5 plants = 3/4 gallons
Now here we have to find how much soil will each plant get.
So we have to apply unitary method here to find how much would each plant get the share of soil.
Soil required by 5 plants = 3/4 gallons
Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons
Answer: Each plant will get 3/20 gallons of soil.
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
Answer:
7(7x -4)
Step-by-step explanation:
49x-28
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
7(7x -4)
