\frac{2}{3}<span>(9+x)=<span>5(4−x)</span></span>Simplify: 
(\frac{2}{3})(9)+(\frac{2}{3})(x)=(5)(4)+(5)(−x)(Distribute)
6+\frac{2}{3}<span>x=<span>20+−5x</span></span>\frac{2}{3}<span>x+6=<span><span>−5x</span>+<span>20
</span></span></span>Step 2: Add 5x to both sides.
\frac{2}{3}x+6+5x=−5x+20+5x
\frac{17}{3}x+6=<span>20
</span>Step 3: Subtract 6 from both sides.\frac{17}{3}<span><span><span>x+6</span>−6</span>=20−6</span>\frac{17}{3}<span>x=<span>14

</span></span><span>Step 4: Multiply both sides by </span>\frac{3}{17}<span>.
</span>(\frac{3}{17} ) · (\frac{17}{3}x ) = (\frac{3}{17})·(14) 
 Answer = (\frac{42}{17}

A pharmaceutical testing company wants to test a new cholesterol drug. The average cholesterol of the target population is 200 m
Rom4ik [11]

Answer:

The required range is 237.5 to 275.

Step-by-step explanation:

Consider the provided information.

The average cholesterol of the target population is 200 mg and they have a standard deviation of 25 mg.

The the value of μ = 200 and the \sigma=25

The company wished to test a sample of people who fall between 1.5 and 3​ z-scores above the mean.

Let the value of z is 1.5.

Now use the z score formula: z=\frac{(x -\mu)}{\sigma}

Substitute the respective values in the above formula.

1.5=\frac{(x -200)}{25}

37.5=x -200

237.5=x

Now let the value of z is 3.

Substitute the respective values in the z score formula.

3=\frac{(x -200)}{25}

75=x -200

275=x

Hence, the required range is 237.5 to 275.

USING OLDER BROS ACC THIS IS HOW MUCH I NEED HELP PLEASE BE QUICK--------------------
lesya692 [45]
Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi 
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.
