Answer:

x = 0

Step-by-step explanation:

We know: 5(x + 6) – 2x = 3(x + 10)

Distribute: 5x + 30 - 2x = 3x + 30

Rearrange equation: 5x - 2x - 2x = 30 - 30

Combine like terms: 1x = 0

Divide: x = 0

What is the 32nd term of the arithmetic sequence where a1 = 12 and a13 = -60

Olin [163]

Answer:

The 32nd term of Arithmetic sequence is -174

Step-by-step explanation:

Given: $a_1=12, a_{13}=-60$

We are given two term of the Arithmetic sequence.

Formula:

$a_n=a+(n-1)d$

For $a_1=12$

$a=12$

For $a_{13}=-60$

$a+12d=-60$

Using two equation solve for a and d

$12+12d=-60$

$1+d=-5$

$d=-6$

We need to find 32nd term

$a_{32}=a+31d$

$a_{32}=12+31(-6)$

$a_{32}=12-186$

$a_{32}=-174$

Hence, The 32nd term of Arithmetic sequence is -174

Are 2/3 and 6/8 equivalent?

miskamm [114]

No they are not, 6/8 could also be represented as 3/4. Therefore they are not equivalent. You would divide each side by the factor they have in common such as 2.

Write an expression for the perimeter of the triangle below.

jekas [21]

Answer:

8.9k

Step-by-step explanation:

We just have to add together the length of the three sides to find the perimeter of the triangle.

(1.8k-5)+(3.5+6.1k)+(k+1.5) = 1.8k-5+3.5+6.1k+k+1.5

Combine like terms.

1.8k-5+3.5+6.1k+k+1.5 = 8.9k + 0

= 8.9k
