Answer:

6

Step-by-step explanation:

S_{n} = \frac{a(1-r^{n}) }{1-r}

63 = -3(1 - -2^{n}) / (1- -2)

63 = (-3 + 6^{n})/3

63 = -1 + 2^{n}

64 = 2^{n}

n = 6

5th grade math. Correct answer will be marked brainliest.
Advocard [28]

Answer:

Least common denominator of 2 and 8: 8

5 x 1 = 5

8 x 1 = 8

1 x 4 = 4

2 x 4 = 8

Step-by-step explanation:

5/8 and 1/2 are not equivalent; the wording is weird on this question, it almost makes it sound as if it wants you to make 5/8 and 1/2 equivalent fractions.

I assume it only wants you to set it up so that in part 2 you will be able to easily figure out how much wire Mr. Barber has used total. Which will be 9/8 yards, by the way. Alternatively, 1 1/8 yards.

A triangle has two sides of length 1 and 2. What compound inequality describes the possible lengths for the third side, x?Write
klemol [59]

Step-by-step explanation:

since in a triangle each side must be shorter than the sum of the other 2 sides (otherwise the end points cannot connect, and there is no triangle), the necessary inequality condition must be

side < 1 + 2 = 3

so,

side < 3

for a lower limit let's go through the cases

1 < 2 + side (is always true)

2 < 1 + side

1 < side (side must be larger than 1)

and again

side < 1 + 2 = 3

side < 3

so the full restriction for the third side is

1 < side < 3
