<span>3 x + 5 x + 4 - x +7 = 88

First, combine like terms.

7x + 11 = 88

Subtract 11 from both sides.

7x = 77

Divide both sides by 7.

x = 11</span>

3x+5x+4-x+7=88
Combining like terms
3x+5x-x+4+7=88
8x-x+11=88
7x+11=88
Subtract 11 to each side
7x+11-11=88-11
7x=77
Divided 7 to each side
7x/7=77/7
x=11
Check:
3x+5x+4-x+7=88
Substitute x with 11
3(11)+5(11)+4-11+7=88
33+55+4-11+7=88
88+4-11+7=88
92-11+7=88
81+7=88
88=88. As a result, x=11. Hope it help!

The average birth weight of elephants is 200 pounds. Assume that the distribution of birth weights is Normal with a standard dev
zhenek [66]

The birth weight of elephants at the 85th percentile is 262.16 pounds

<h3>What is the standard deviation?</h3>

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

Given that:-

The average birth weight of elephants is 200 pounds    \mu = 200

The deviation of 60 pounds.                                              \sigma = 60

The birth weight of elephants at the 85th percentile.      z = 85%= 1.036

Now from the formula of z-score:-

z=\dfrac{x-\mu}{\sigma}\\\\\\z=\dfrac{x-200}{60}\\\\\\1.036\times 60=x-200\\\\\\x=\ \ 262.16\ pounds

Hence the birth weight of elephants at the 85th percentile is 262.16 pounds
