2/9 +1/3=5/9
this means you read a total of 5/9 of your book on Friday and Saturday. so to finish your book, you must have read 4/9 of it on Sunday. If (4/9)x=120, x=270; your book has 270 pages.
1 kg= 1000g
So, if there are 2.5kg, then there are 2500g.
That way, 2500-750=1750
You can say there are 1750g of popcorn left or 1.75kg of it left.
(P.S.- Who eats that much popcorn? lol)
I hope that helped.
Answer:
The answer is y = -15x + 35.
Step-by-step explanation:
We want to isolate y, so we cancel everything on that side of the equals except y. We begin with the term farthest away from y, which would be 3x. Since it is positive, to cancel it we will subtract. This will give us 1/5y = 7-3x.
Next we want to cancel the 1/5. Since it is directly beside y, this means it has been multiplied; to cancel, we will divide. Divide both sides by 1/5, and we have y = (7-3x)÷(1/5). When we divide fractions, we flip the second one and multiply; this means we have y=(7-3x)*5.
Using the distributive property, we have y=7*5-3x*5, which gives us y=35-15x. We can write this as y=-15x+35.
If the population of the animals decreases by about 21% of its current population, it means that the population next year is only 1 - 0.21 or 0.79 of its current population. Thus, the multiplier for the rate of the exponential decay is 0.79.
