When solving multi-step equation you should start by combining like terms.

4x + 10 = 7x + 16

With this equation you can subtract 4x from each side. -4x = -4x

10 = 3x + 16

Then you can combine 16 and 10 by subtracting 16 from each side. -16 = -16

-6 = 3x

After that you try and isolate the variable. You can do this by dividing both sides by 3 which also isolates the variable. *1/3 = *1/3

-2 = x

So the final answer would be x = -2

We are given:

4x+10=7x+16

Our goal in solving for any variable, in this case is x, we need to isolate x on one side of the variable. Let's start by subtracting 7x from both sides, which will cancel the +7x on the right side. We are then left with:

-3x+10=16

Now, we want to move that +10 to the other side so our x is all by itself. Let's subtract 10 from both sides, which will cancel the +10 on the right leaving us with:

-3x=6

Since we cannot have a coefficient when solving for x, we need to divide both sides by -3.

\frac{-3x}{-3}={\frac{6}{-3}

When we divide, our answer is:

x=-2

Which one is correct?
nordsb [41]

Answer:

SSS or SAS

Step-by-step explanation:

Remark

Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.

1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.

2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.

Fun Tees is offering a 30% discount on all merchandise. Find the discounted price of a T-shirt originally priced at $16. Solve i
frozen [14]

Answer:

Step-by-step explanation:

Discount = % discount × cost price given.

Discounted price = cost price - discount

% discount = 30%

cost price given = $16

Discount = % discount × cost price given.

= (30/100) × $16

= $4.8

Giveaway price = $16 - $4.8

= $11.2

Michael has 1.85 in dimes and nickels.He has a total of 25 coins.how many of each does he have
creativ13 [48]
D+n=25 subtract d from both sides *(if your wondering what d and n are it stands for Dimes and Nickels)* n=25-d   
0.10d+0.05= 1.85
0.10d+0.05(25-d)= 1.85
0.10d+1.25-0.05d= 1.85
0.05d = 0.60
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My answer: He has 12 dimes (d=12) and 25-12=13 so 13 nickels.. Hope this helps! :)

Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?
irga5000 [103]

Answer:

La probabilidad que hay de que sea fin de semana es \frac{2}{7}

Step-by-step explanation:

La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.

P(A)=\frac{numero de casos favorables}{numero de casos posibles}

En este caso:

  • número de casos favorables: 2 (cantidad de días del fin de semana)
  • número de casos posibles: 7 (cantidad de días totales en la semana)

Reemplazando:

P(A)= \frac{2}{7}

<u><em>La probabilidad que hay de que sea fin de semana es </em></u>\frac{2}{7}<u><em></em></u>
