X=10 , using pemdas you multiply the -2 into the parentheses getting yourself 6x+2-4x+3=25 from there you combine like terms and end up with 2x+5=25 and you subtract the 5 from both sides to isolate the x and end up with 2x=20 and then divide the 2 to finally isolate the x and end up with X=10

Y-4x=3. 2x-3y=21 can someone help

mars1129 [50]

Y-4X =3 ; 2x-3y=21

Y= 3+ 4x

2x -3( 3+4x)= 21

2x- 9- 12x= 21

-10x -9= 21

-10x -9+9= 21+9

-10x = 30

X= 30/-10= -3

Y= 3+4x = 3+ 4* (-3)= 3-12= -9

Giving triangle and m what is m >b

Gelneren [198K]

Since you know the triangles are congruent/equal, you know that:

m∠A and m∠X are congruent and have the same angle, and so does:

m∠B and m∠Y

m∠C and m∠Z

A triangle is 180°. (the 3 angles have to add up to 180) To find m∠B, you can do this:

m∠A + m∠B + m∠C = 180°

21° + m∠B + 35° = 180° Subtract 21 and 35 on both sides

m∠B = 124° your answer is C

The board of examiners that administers the real estate broker's examination in a certain state found that the mean score on the

Goshia [24]

Answer:

The passing score is 645.2

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:

$\mu = 553, \sigma = 72$
