Hey!

-----------------------------

Question 16:

6 - x = 10

6 + (-x) = 10

6 + (-x) -6 = 10 - 6

-x = 4

-x/-1 = 4/-1

-----------------------------

Question 17:

4x + 3 = 9

4x + 3 - 3 = 9 - 3

4x = 6

4x/4 = 6/4

-----------------------------

Hope this helped, good luck!

Answers:

16. 6-x= 10

move +6 to the other side

sign changes from +6 to -6

6-6-x= 10-6

-x= 4

Mutiply both sides by -1

(-1)(-x)= (-1)(4)

x= -4

17. 4a+3= -9

move +3 to the other side

sign changes from +3 to -3

4a+3-3= -9-3

4a= -12

divide both sides by 4

4a/4= -12/4

a= -3

If PQRS is a rhombus, which statements must be true? Check all that apply.

Aleksandr [31]

Answer:

Options (B), (C) and (F) are correct.

Step-by-step explanation:

Properties of a rhombus,

1). All sides of a rhombus are equal in measure.

2). Both the diagonals of a rhombus are the perpendicular.

3). Diagonals bisect the vertex angles.

By these properties of a rhombus,

Option (B): PR is perpendicular to QS.

Option (C): ∠QPR ≅ ∠SPR

Option (F): PQ ≅ QR

Therefore, options (B), (C) and (F) are correct.

Cody said that dividing a unit fraction by a whole number is the same as multiplying the unit fractions by a unit fraction with

LekaFEV [45]

Answer:

True

Step-by-step explanation:

Hi, the statement is true, because to divide a fraction we have to turn the second fraction upside down and multiply them. Since a whole number x can be written as x/1, it also applies to the case of dividing a fraction by a whole number.

We can prove it with an example.

Dividing a unit fraction by a whole number

1/2 ÷ 2 = (1x1) / (2x2) = 1/4

Multiplying the unit fractions by a unit fraction with a whole number as a denominator

1/2 x 1/2= (1x1) / (2x2) = 1/4

A person must score in the upper 8% of the population on an IQ test to qualify for membership in MENSA, the international high-I

Cloud [144]

Answer:

A person must get an IQ score of at least 138.885 to qualify.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 115, \sigma = 17$
