What is the value of x in the equation 3/4x+4=5/8
Radda [10]
\frac{3x}{4} +4= \frac{5}{8}
Multiply both sides by 8.
2(3x) + 8(4)= 5
6x+32=5
Subtract 32 from both sides
6x=-27
Divide both sides by 6.
x=-27/6
Simplify
x=-9/2

Answer:

The question is open ended as i suppose since there are infinitely many possibilities. one possible form of the solution can be 5^{2}

Step-by-step explanation:

The base in this case is 5 while the exponent is simply the power to which the base is raised in which case it would be 2. Both values are positive and the exponent is less than the base.

Suppose SAT Writing score are normally distributed a mean of 497 and a standard deviation of 114. A university plans to admit st
Olin [163]

Answer:

The minimum score required for admission to the nearest whole number = 557

Step-by-step explanation:

We solve this using z score formula.

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Top 30% of the candidates is a ranking that is equivalent to = 100 - 30% = 70th percentile.

The z score of 70th percentile = 0.524

Mean = 497

Standard deviation of 114.

Minimum score = raw score = ???

Hence:

0.524 = x - 497/114

Cross Multiply

0.524 × 114 = x - 497

59.736 = x - 497

x = 59.736 + 497

x = 556.736

The minimum score required for admission to the nearest whole number = 557
