1/2x - 4 = 1/3x + 5

Mamont248 [21]

Answer:

X = 54

Step-by-step explanation:

Let's solve your equation step-by-step.

1/2x−4=1/3x+5

Step 1: Subtract 1/3x from both sides.

1/2x−4−1/3x=1/3x+5−1/3x

1/6x−4=5

Step 2: Add 4 to both sides.

1/6x−4+4=5+4

1/6x=9

Step 3: Multiply both sides by 6.

6*(1/6x)=(6)*(9)

x=54

Four consecutive multiples of 6 yield a sum of 156. What are these multiples?

olga nikolaevna [1]

Let x be the first number:
1st number: = x
2nd consecutive multiple of 6 = x+6
3rd consecutive multiple of 6 = x+12
4rth consecutive multiple of 6 = x+18
Their sum = 156 → x+(x+6)+(x+12)+(x+18) = 156
4x +30 = 156
4x = 120 and x = 30

The numbers are: 30,36,42,48

Calculate the sum of the infinite series 98+84+72+432/7+...

bogdanovich [222]

ANSWER

$S_\infty= 686$

EXPLANATION

The given infinite series is

$98 + 84 + 72 + \frac{432}{7} + ...$

The sum to infinity of this series is given by the formula,

$S_\infty= \frac{a_1}{1 - r}$

where the first term of this infinite geometric series is

$a_1 = 98$

and the common ratio is
$r = \frac{a_2}{a_1}$

$r = \frac{72}{98} = \frac{6}{7}$

We substitute these values to obtain,

$S_\infty= \frac{98}{1 - \frac{6}{7} }$

We simplify the denominator to get,

$S_\infty= \frac{98}{\frac{1}{7} }$

This simplifies to

$S_\infty= 98 \times 7 = 686$
