The answer is 1848

Sum of arithmetic sequence:
s = n(a1 + an)/2

n - number of terms
a1 - the first therm
an - n-th term

an = a1 + (n - 1)d
d - common difference

n = 24
a1 = 8
d = 6       (14 - 8 = 6;    20 - 14 = 6)
an = 8 + (24 - 1) * 6 = 8 + 23 * 6 = 146

s = n(a1 + an)/2
s = 24 * (8 + 146) / 2
   = 24 * 154 / 2
   = 1848

I need help please will give brainliest
EleoNora [17]

Answer:

1.) True, because it says three times so you know the x belongs there. Also, you have to follow the order of what the problem says.

2.) False, because it is not in the order of how the problem states it.

3.) False, because if you transfer the fraction to a decimal you get 4.333333. It's not valid.

4.) True, because if you do 7 × 3, it equals to 21. So, 21 - 17 = 4. And Jenny is supposed to have 4 quilts.

Hope it helps! :D

You and your friend both babysit. The ratio of the amount of money you make to the amount of money your friend makes is 5:3. You
WITCHER [35]

Answer:

Money made by you =$55

Money made by your friend = $33

Step-by-step explanation:

Given:

The ratio of the amount of money you make to the amount of money your friend makes = 5:3

The total amount made = $88

To find money made by each of them using tape diagrams.

Solution:

The tape diagram for the given situation is shown below.

Money mad by you is represented by 5 rectangles

Money mad by your friend is represented by 3 rectangles

Total number of rectangles = 5+3 = 8

Thus, 8 rectangle represent a total of $88.

We have

8\ rectangles =\$88

Dividing both sides by 8, we have:

\frac{8}{8}\ rectangles =\$\frac{88}{8}

1\ rectangle =\$11

So, money made by you will be:

5\ rectangles =5\times \$11=\$55

Money made by your friend will be:

3\ rectangle =3\times \$11=\$33
