Solve for x:<br><br> 2+x=8-x

dsp73

2+x=8-x

add x to each side to get all the x's on one side

2+x+x = 8-x+x

2 + 2x = 8

now subtract 2 from each side to get all the numbers on the other side

2 + 2x -2 = 8-2

2x = 6

divide by 2 on each side to get x alone

2x/2 = 6/2

x=3

Answer: x=3

Algebra 1 help please

Karo-lina-s [1.5K]

Short leg = 18 Long leg= 24 Hypotenuse= 30 My calculations were simple trial and error. I started with a trial of 10 for the short leg to begin with, averaging and estimating the appropriate proportions based off 6 additional increments. Sorry I don't have an algebraic method for you. Hope this has helped somewhat :)

Which equation could be used to calculate the sum of the geometric series? one-third two-ninths startfraction 4 over 27 endfract

Andrew [12]

The equation could be used to calculate the sum of the geometric series is $S_n=\dfrac{\frac{1}{3} (1-(\frac{2}{3} )^n)}{1-\frac{2}{3} }$

<h3>Sum of geometric sequence</h3>

Geometric sequence are sequence that increase expoentially. The formula for calculating the sum of an exponential sequence is expressed as:

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

where

a is the first term
n is the number of terms
r is the common ratio

From the given sequence

a= 1/3

r = 2/9 * 3 = 2/3

Substitute into the formula

$S_n=\dfrac{\frac{1}{3} (1-(\frac{2}{3} )^n)}{1-\frac{2}{3} }$

Hence the equation could be used to calculate the sum of the geometric series is $S_n=\dfrac{\frac{1}{3} (1-(\frac{2}{3} )^n)}{1-\frac{2}{3} }$
