Answer:

  5461

Step-by-step explanation:

You can recognize this as the sum of 7 terms of a geometric series with first term 1 and common ratio 4.

That sum is given by ...

  S_n=a_1\cdot\dfrac{r^n-1}{r-1}

where a1 is the first term and r is the common ratio.

Filling in the numbers, we have ...

  S_7=1\cdot\dfrac{4^7-1}{4-1}=\dfrac{16384-1}{3}=5461

The sum is 5461.

Jelly ate 3 apples. This represents 50% of the bag of apples. How many apples were originally in the bag
rjkz [21]
<h3>Answer:  6 apples</h3>

x = number of apples originally

50% of x = 0.50*x = amount of apples eaten = 3

0.50x = 3

x = 3/0.50 ....... divide both sides by 0.50

x = 6

You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.

2 times 8 equals 16 plus 3 would equal ~~19~~

3 times 6 equals 18 minus 2 times 8 would equal ~~16~~

5 times 6 equals 30 plus 8 times 1/2 equals ~~19~~

(3 times 8 equals 24 plus six equals 30) 2 times 30 equals 60 divided by (10 times 3 equals 30) 30 equals ~~2~~
