3/8+3/10 in lowest form

1 answer:

3 0

Find the common denominator.

8 and 10 have the common denominator of 80.

So 30/80 + 24/80

= 54/80

But we have to simplify it.
54/80 = 27/40

Determine the type and number of solutions of x^2 + 10x − 25 = 0.

Vitek1552 [10]

Answer:

There is exactly 1 solution and it is a double root.

Step-by-step explanation:

To find this, factor the equation and solve.

x^2 + 10x - 25 = 0

(x - 5)(x - 5) = 0

Now that we have this factored, we can set each parenthesis equal to 0 and solve separately.

x - 5 = 0

x = 5

x - 5 = 0

x = 5

Because there are two of the exact same answer, we know it to be a double root.

Solve this Algebra problem please, I can't figure it out.

vladimir1956 [14]

Answer:

$45927/4096$

Step-by-step explanation:

Given is the geometric series, because the ratio of consecutive terms is common:

$r = 84/112 = 63/84 = 3/4$

The first term is 112.

So the nth term is:

$t_n = t_1*r^{n-1}$

The 9th term is:

$t_9 = 112*(3/4)^8=45927/4096$
