What is 9x+1=7x-9? Help, please :) thanks.

Answer:

X=1/4L OR 0.25L OR 250ml.

Step-by-step explanation:

Answer:

x = 22.5

Step-by-step explanation:

Step 1: Write equation

2.4(x - 10) = 8 + 1.2x - 5

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

2.4(22.5 - 10) = 8 + 1.2(22.5) - 5

2.4(12.5) = 8 + 27 - 5

30 = 8 + 22

30 = 30

Answer:

x=22.5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2.4(x−10)=8+1.2x−5

(2.4)(x)+(2.4)(−10)=8+1.2x+−5(Distribute)

2.4x+−24=8+1.2x+−5

2.4x−24=(1.2x)+(8+−5)(Combine Like Terms)

2.4x−24=1.2x+3

2.4x−24=1.2x+3

Step 2: Subtract 1.2x from both sides.

2.4x−24−1.2x=1.2x+3−1.2x

1.2x−24=3

Step 3: Add 24 to both sides.

1.2x−24+24=3+24

1.2x=27

Step 4: Divide both sides by 1.2.

1.2x

1.2

=

27

1.2

x=22.5

Answer:

x=22.5

Sorry. Had to redo this with the correct answer.

Here it is...

Solve for x by simplifying both sides of the equation, then isolating the variable.

Exact Form:

x = - 2/5 (fraction)

Decimal Form:

x = - 0.4 (decimal)

Answer:

F ( x ) = ( 6 x +9 )

Step-by-step explanation:

Change to slope-intercept form y = mx + b:

y - 6x - 9 = 0

y = 6x + 9

As function notation where x is the independent variable: f(x) = 6x + 9

X= 8/3 :)) hope this helps !

Answer:

100

Step-by-step explanation:

You move the decimal to the left, 2 times.

You can only move it over like that if you are working with 10, 100, 1,00, ect.

If you were multiplying you would move it to the right.

Answer:

100

Step-by-step explanation:

You may need to remove the comma

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

Explanation:

Start with 1.95 and move the decimal point 5 spots to the right to get 195,000

Or you could have this as your steps maybe

1.95 × 10^5

1.95 × 100,000

195,000

The exponent over the 10 tells us how many spaces to move. If the exponent was negative, then we would move the decimal point to the left.

Answer:

-8.18800

Step-by-step explanation:

-8.188

-3.56 times 2.3 = -8.188

Answer:

y = 1

x = -0.75

Step-by-step explanation:

The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.

21y - 1 = 4x + 23

21y - 24 = 4x

5.25y - 6 = x

21y - 1 = 4x + 23

21y = 4x + 24

y = 4/21(5.25 - 6) + 1.14

y = 1 - 1.14 + 1.14

y = 1

5.25(1) - 6 = x

-0.75 = x

Answer:

Erica has 15 pieces of candy left

Step-by-step explanation:

Mark me brainliest!!!!

She had 45 pieces to start with then she gave her friends 1/3 which leaves her with 15 pieces of candy left. Then she eats 1/6 of the candy she had left so now she only has 25 left and then the next day she eats 10 more pieces which leaves her with 15 pieces of candy left.

Answer:

Answer: Osvoldo did not meet his goal.

Step-by-step explanation:

Total carbohydrate ate by Osvoldo = 220 g

carbohydrate from grains = 55 g

Percentage of carbohydrate of grain is

\begin{gathered}=\dfrac{\text { carbohydrate taken from grains}}{\text {Total carbohydrate}} \times 100\\\\= \dfrac{55}{220} \times 100= 25 \%\end{gathered}

=

Total carbohydrate

carbohydrate taken from grains

×100

=

220

55

×100=25%

Goal of getting carbohydrate from grains = at least 30%

but he ate only 25% of carbohydrate

Hence, Osvoldo did not meet his goal as he ate less carbohydrate than his goal.

Step-by-step explanation:

3x+12-4=2x+8+x

3x+8=2x+8+x

3x+8=3x+8

sub tract 3x on both sides and poof

we get 8 =8

Answer:

2

Step-by-step explanation:

The answer is the second explanation I think

Answer:

it's the 2nd answer

Step-by-step explanation:

basically I just found the range and it kinda gave me the answer (range is the difference between the highest and lowest number, so 24-9=15)

Answer: See explanation

Step-by-step explanation:

1. Cost = $413

Sales percent = 6.5%

Cost of bike = $413 + (6.5% × $413)

= $413 + (0.065 × $413)

= $413 + $26.845

= $439.85

2. Cost of dishwasher = $569

Commission rate = 18%

The expression for the commission will be:

= 18% × $569

= 18/100 × $569

= 0.18($569)

Answer:

X

Step-by-step explanation:

Each input should have one output.

Answer:

x = 32°

y = 17°

Step-by-step explanation:

Let's look at the bottom triangle since it has two angles.

62° + 75° = 137°

180° - 137° = 43°

The missing angle measure is 43°. Since the two angles make up a straight line,

(4x + 9)° + 43° = 180

4x + 52° = 180°

4x = 128°

x = 32°

The angle measuring 62° is a vertical angle so the angle opposite it is also 62°. The missing angle for that triangle would 40° because 180° - 140° = 40°.

62° + 40° = 102°

180° - 102° = 78°

(5y - 7)° = 78°

5y = 85°

y = 17°

Hope that helps.

Answer:

16.5

Step-by-step explanation:

Answer: 16.50

Step-by-step explanation:

First, you need to divide 27.50 by 5. (It's easier to multiply the number by 100 so it's 2750, then divide the quotient by 100 to get the actual answer). Then after you divide 27.50 by 5 you will get 5.50. Multiply that by 3 and get 16.50!

Answer:

a=-1.5 (lmk if im incorrect)

Step-by-step explanation:

-16 - 7(2a + 3) = 23 - 2a

-16-(14a+21)=23-2a

5-14a=23-2a

5=23+12a

-18=12a

-18/12 is -1.5

a=-1.5

Answer:

9.75

Step-by-step explanation:

first we are going to subtract the bonus

142.25 -35 = 107.25

assuming that you are not takeing breaks you work a total of 11 hours (7+4)

so 11/107.25  = 9.75

so you would make 9.75 an hour before taxs

Answer:

La cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

Sabes que en el primer aeropuerto se bajan la mitad de los pasajeros, es decir que se bajan [tex]\frac{1}{2}[/tex] pasajeros, y en la segunda parada llegando a destino se bajan [tex]\frac{1}{3}[/tex] pasajeros. Entonces, la cantidad de pasajeros que se bajan en ambas paradas es la suma de la cantidad de pasajeros que se bajaron entre el primer y segundo aeropuerto:

[tex]\frac{1}{2}+\frac{1}{3}[/tex]

Lo primero que debes hacer es hayar un denominador común entre el 2 y el 3. Para eso, hallas el mínimo común múltiplo entre ambos, en este caso 6.

Luego debes multiplicar cada numerador por el número que hayas multiplicado el denominador. Para ello, dividis este mínimo común múltiplo entre el denominador inicial, y este resultado se multiplica por el numerador de esa fracción. De esta manera se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{3}{6} +\frac{2}{6}[/tex]

Finalmente se suman los numeradores y se obtiene:

[tex]\frac{1}{2}+\frac{1}{3}=\frac{5}{6}[/tex]

Considerando que 1 es un entero que representa la cantidad de total de pasajeros, para calcular la cantidad de pasajeros que quedan en el avión se realiza la sustracción:

[tex]1-\frac{5}{6}[/tex]

Resolviendo de manera similar a la suma, se obtiene:

[tex]1-\frac{5}{6}=\frac{6}{6} -\frac{5}{6}[/tex]

[tex]1-\frac{5}{6}=\frac{1}{6}[/tex]

Entonces la cantidad de pasajeros que quedan en el avión serán [tex]\frac{1}{6}[/tex]
