\rule{50}{1}\large\blue\textsf{\textbf{Answer and how to solve:-}}}}

\dagger First, subtract 3 on both sides:-

                                       \bold{-3x < 6-3}

\dagger On simplification,

                                  \bold{-3x < 3}

\dagger Now, divide by -3 on both sides:-

               \bold{x > -1}

\bigstar The sign changed because we divided by a negative number on both sides.

<h3>Good luck with your studies.</h3>

A chemist wishes to mix a solution that is 12% acid. She has on hand 6 liters of a 4% acid solution and wishes to add some 16% a
Damm [24]

Answer:

25 liters of the 16% solution should be added.

Step-by-step explanation:

pure acid amount + pure acid amount = total pure acid amount

0.02*10          + 0.16*x           = 0.12*(10+x)     <<<---=== it is your balance equation;  x is the amount (in liters) of the 16% solution.

0.02*10 + 0.16x = 0.12*10 + 0.12*x

0.16*x - 0.12*x = 0.12*10 - 0.02*10

(0.16 - 0.12)*x = 0.12*10 - 0.02*10

x = %280.12%2A10-0.02%2A10%29%2F%280.16-0.12%29 = 25.

Answer.  25 liters of the 16% solution should be added.

Check.   %280.02%2A10+%2B+0.16%2A25%29%2F%2810+%2B+25%29 = 0.12 = 12% of concentration of the final mixture.   ! Correct !

Triangle weigh 6, how much does square weigh, this is a balanced hanger
Naya [18.7K]

Answer:

9

Step-by-step explanation:

set triangles as x and squares as y

x+3y=4x+y, now plug in 6 for each triangle

6+3y=4(6)+y, solve for the weight of the squares

3y-y=24-6

2y=18

y=9, each sqaure weighs 9 units

A pole 24 feet high has a shadow 8 feet long.a nearby pole is 72 feet high. how long is it's shadow?
Dmitry [639]
The answer is 24. If you cross multiply witht he eight over top of the twenty-four, and the x (unknown length of shadow) over seventy-two and cross multiply (8 times 72, x times 24) then get 576 = 24x and divide twenty four on both sides, then that should give you the correct answer.

In triangle $ABC$, the angles $\angle A$, $\angle B$, $\angle C$ form an arithmetic sequence. If $\angle A = 23^\circ$, then wha
LenKa [72]

Answer:

97^0

Step-by-step explanation:

Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.

The nth term of an Arithmetic sequence is given by the formula: T_n=a+(n-1)d

Where:

a=first term

n=number of term

d=common difference

In this case,

Angle \:A, a=23^0

Angle B, T_2=23+(2-1)d=(23+d)^0\\Angle C, T_3=23+(3-1)d=(23+2d)^0

The sum of angles in a triangle is 180 degrees. Therefore:

∠A+∠B+∠C=180 degrees

23^0+(23+d)^0+(23+2d)^0=180\\69^0+3d=180^0\\3d=180^0-69^0\\3d=111^0\\d=37^0

Therefore:

Angle C,

(23+2d)^0=(23+2(37))^0=23+74\\C=97^0
