Answer:

n = 5/7 or 0.7

Step-by-step explanation:

The goal is to isolate the variable N. First, you distribute the fractions to their repsective parentheses.

1/2(5n + 8) = 3/4(12 - 6n)

2.5n + 4 = 9 - 4.5n

2.5n + 4.5n = 9 - 4

7n = 5

Divide both sides by 7, and you get n = 5/7 or 0.7

What is the value of 2×[34−5×(3+1)] ?

spayn [35]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{28}}}}}$

Step-by-step explanation:

Use BODMAS rule :

Bracket , Of , Division , Multiplication , Addition , Subtraction

$\sf{2 \times [ 34 - 5 \times (3 + 1) ] }$

Add the numbers : 3 and 1

$\dashrightarrow{ \sf{2 \times [ 34 - 5 \times 4 ] }}$

Multiply the numbers : 5 and 4

$\dashrightarrow{ \sf{2 \times [ 34 - 20 \: ] }}$

Subtract 20 from 34

$\dashrightarrow{ \sf{2 \times 14}}$

Multiply the numbers : 2 and 14

$\dashrightarrow{ \sf{28}}$

Hope I helped!

Best regards! :D

ILL GIVE YOU BRAINLIST !!!! What is the slope of this table?

VLD [36.1K]

Answer: Slope is m = 2/3

Step-by-step explanation:

-You have exactly four points on a table:

$(3,2) (6,4) (9,6) (12,8)$

-Use the slope formula and use any two points from those four points in order to find the slope:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

-The two points I use are $(3, 2)$ and $(6,4 )$ for the equation:

$m = \frac{4 - 2}{6-3}$

$m= \frac{2}{3}$

So, the slope of the table is $\frac{2}{3}$ .
