Answer:

<u>2 1/6x +10</u>

Step-by-step explanation:

All you need to do is combine like terms.

3/2x+<u>4</u>+2/3x+<u>6</u>

3/2x+<u>10</u>+2/3x

<u>3/2x + 2/3x</u>= <u>2 1/6x</u>

<u>2 1/6x+10</u>

Find the measures of the angles given
dexar [7]

Answer:

BCD = 60

ABD - 90

Step-by-step explanation:

BCD)

BC and CD are the same length on in the circle, they are the radius. Therefor,  all angles will be the same at 60

ABD)

All angles together are 180

You know 2 Angles, A at 30 and D at 60

180 - 30 - 60 = Angle B

90 = Angle B

A scientist estimated that a mixture would need 4 milliliters of a chemical to balance. The actual amount needed was 7 millilite
Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.

Keywords: error, percentage

Using fluorescent imaging techniques, researchers observed that the position of binding sites on HIV peptides is approximately N
konstantin123 [22]

Answer:

The values is  

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu  =  2.45

    The  standard deviation is  \sigma  = 0.35 \ mi

     The random value is  x =   2.03

The standardized score for a binding site position of 2.03 microns is mathematically represented as

       z-score  =  \frac{x -  \mu}{ \sigma }

=>      z-score  =  \frac{2.03 -  2.45}{ 0.35}

=>    z-score  =  -1.2

Please help
Firlakuza [10]

Answer:

Step-by-step explanation:

y = -2/3 x       multiply both sides the first equation by 6

6y = -4x                    Add 4x to both sides.

6y + 4x = 0

<u>-9y +4x = - 40   </u>        Subtract the bottom equation

15y =  - 40                 Divide by 15

y = -40/15

y = - 2.7

======================

6y = -4x

6*(-2.67) = -4x

-16 = - 4x

x = - 16/-4

x = 4
