Find the 25th term of the arithmetic sequence when a1 = -14 and d = -5

Mathematics
1 answer:
rosijanka [135]2 years ago
6 0

Answer:

  a25 = -134

Step-by-step explanation:

For first term a1 and common difference d, the formula for the n-th term is ...

  an = a1 + d(n -1)

You want to evaluate this for n=25, a1=-14, d=-5. Filling in the numbers and doing the arithmetic, you get ...

  a25 = -14 -5(25 -1) = -14 -120

  a25 = -134

A large bag contains 5/12 pounds of nails. How many 1/8 pounds bags can be filled with this amount of nails?
Amanda [17]

so, three bags can be filled and 0.33 or 0.33*(1/3) =11/100 nails will be left

Step-by-step explanation:

We will get the number of bags that can be filled from 5/12 by dividing the total amount by the 1/8

Given

Total nails in bag = 5/12 pounds

The capacity of small bag = 1/8 pounds

So,

Number\ of\ bags = \frac{\frac{5}{12}}{\frac{1}{8}}\\Simplifying\\=\frac{5}{12}*\frac{8}{1}\\=\frac{40}{12}\\=3.33\ bags

so, three bags can be filled and 0.33*(1/3) = 11/100 nails will be left

Solve the “and” compound inequality for –1 < 6x + 1 ≤ 13
ser-zykov [4K]

Answer:

-1/3 < x <(or equal to) 2

Step-by-step explanation:

Firstly divide your inequality into two separate inequalities...

1) -1 < 6x + 1...then solve for the first one..,which then gives you....;

-2 < 6x....which gives us our first solution (x > -1/3)

Then the second inequality

2) 6x + 1 <(or equal to) 13

which then gives you....,

6x <(or equal to) 12...which then gives our second solution...( x <(or equal to) 2)

Then combine the two solutions into a compound solution

-1/3 < x <(or equal to) 2
