What is <br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B2ax%20%2B%203%7D%7Bax%20%2B%203%7D%20%20%3D%20%20-%201" id="TexFormul

\dfrac{2ax+3}{ax+3}=-1

Rewrite -1 as a fraction

\dfrac{2ax+3}{ax+3}=\dfrac{-1}{1}

Cross multiply

2ax+3=-1(ax+3)

Distribute the -1

2ax+3=-ax-3

Add both sides by ax

3ax+3=-3

Subtract both sides by 3

3ax=-6

Divide both sides by 3a

x=-\dfrac{6}{3a}

Simplify

=-\dfrac{2}{a}

That's the value of x respect to a. Let me know if you need any clarifications, thanks!

What is the total cost if the shirt cost $40 and 20% off
Eddi Din [679]
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.

40 × 0.20 = 8

So now you would subtract 8 from the cost of 40.

 40 - 8 = 32.

The shirt costs $32.

Suppose 180 geology students measure the mass of an ore sample. due to human error and limitations in the reliability of the​ ba
Over [174]

Given the total number of students are 180, the mean of data is 88g, and standard deviation is 1g.

A normal curve is a bell-shaped curve with symmetry about the mean and it spreads uniformly on both sides (left side and right side) of the mean.

The empirical rule is also called "68-95-99.7" rule. It says that :-

A) 68% of the data values fall between 1 standard deviation about mean (34% on left side and 34% on right side),

B) 95% of the data values fall between 2 standard deviations about mean (47.5% on left side and 47.5% on right side), and

C) 99.7% of the data values fall between 3 standard deviations about mean (49.85% on left side and 49.85% on right side).

According to distribution of normal curve and "68-95-99.7" empirical rule, we can say 49.85% of data values are above the mean within 3 standard deviations.

So it means 49.85% of total students report readings more than 88g.

Number of students reporting readings more than 88g = 49.85% of 180 = 0.4985 × 180 = 89.73

Hence, approximately 89 students report readings more than mean value.
