Answer:
6t = -21
Step-by-step explanation:
3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:
3t -5t -7 +7 = 5t-5t+7
-2t = 7
t = -7/2
Then 6t = 6*-7/2 = -21
Answer:
0.5158
Step-by-step explanation:
The exponential decay of a given material is used to describe the process by which a material decreases in size and amount over a specific period of time. The material will decay with respect to its decay factor. Therefore, if the 10-hour decay factor is approximately 0.2661, the 5-hour growth/decay factor will be: (0.2661)^(5/10) = (0.2661)^0.5 = 0.5158.
In real life when I hear the word distribute, I know that it means that something is being handed out. In business, there is something called a distributor and they hand out stuff from the company that you buy it from. In mathematics, it means that you're giving another number something from another number.

Answer: 75
Step-by-step explanation:
Step-by-step explanation:
In order to cover his backyard with sod, he needs to cover the area of the backyard.
His backyard is a rectangle, and area of a rectangle represented by A is given as l*w
Where,
is the length, and
is the width
So, the area of Jim's backyard is square yards.
l*w=12/5/6*10/2/5=2002/15 or 133.466
The area of each sods are solved using the area of the rectangle formula.
l*w=1/1/3*1/1/3=16/9
To find HOW MANY of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:
=2002/15 divided by 16 /9=3003/40or 75.075
Since, fractional sods can't be bought, Jim has to buy 75 sods approximately .
