2x + 2 dollars, because you're adding x and x + 2

How do you make a fraction into a mixed number?

Dennis_Churaev [7]

Ex: 12/5 so first u find the multiple or factor i think of 12 that won't go over which is 10 so it would be 2 2/5 cuz. 5 x 2 = 10 + 2 = 12= 12/5

Calcula y comprueba las ecuaciones: porfavor alguienn la nesesito pliss a) 2X = 6 b) 10 + Z = 20 c) P + 9 = 11 d) 3X + 8 = + 29

Alexeev081 [22]

Answer:

a) x = 3

b) z = 10

c) p = 2

d) x = 7

e) u = 1

Step-by-step explanation:

a) 2x = 6

Despejamos x dividiendo por 2 a amabos lados de la eacuacion.

(2/2)x = 6/2

x = 3

Si remplazamos x en la ecuación original:

2(3)=6

6 = 6

Queda demostrado.

b) 10 + z = 20

Despejamos z restando 10 en amabos lados de la eacuacion.

10-10+z = 20-10

z = 10

Si remplazamos z en la ecuación original:

10 + 10=20

20 = 20

Queda demostrado.

c) p + 9 = 11

Despejamos p restando 9 en amabos lados de la eacuacion.

p + 9 - 9 = 11-9

p = 2

Si remplazamos p en la ecuación original:

2 + 9 = 11

11 = 11

Queda demostrado.

d) 3x + 8 = 29

Despejamos x restando 8 en amabos lados de la eacuacion y luego divideindo por 3 en ambos lados de la ecuación.

3x+8-8 = 29-8

3x = 21

(3/3)x = 21/3

x = 7

Si remplazamos x en la ecuación original:

3(7) + 8 = 29

21 + 8 = 29

29 = 29

Queda demostrado

e) 2u + 8 = 10

Despejamos u restando 8 en amabos lados de la eacuacion y luego divideindo por 2 en ambos lados de la ecuación.

2u+8-8 = 10-8

2x = 2

(2/2)x = 2/2

x = 1

Si remplazamos x en la ecuación original:

2(1) + 8 = 10

2 + 8 = 10

10 = 10

Queda demostrado

17/18 - 8/9 equal out to

Nutka1998 [239]

$\frac{17}{18}$ - $\frac{8}{9}$ =x
You must find a common denominator(bottom)
$\frac{8}{9}$ × $\frac{2}{2}$ = $\frac{16}{18}$
$\frac{17}{18}$ - $\frac{16}{18}$ = $\frac{1}{18}$
Your answer is x= $\frac{1}{18}$

What is the standard form of the equation y=-5/2x-3 ?

butalik [34]

The standard form of an equation is the form where that equation has no fractions and is written in the form ax + by = c.

To get rid of the fractions in y = -5/2 x - 3, we need to multiply both sides by 2. That makes the equation become:

2y = -5x - 6

Now we need to get it into the form ax + by = c. We can do this by adding 5x to each side.

5x + 2y = -6 is our answer

Help me, please !!!!!

vova2212 [387]

Answer: 100

Hi!

ok so the Pythagorean theorem is

$c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10$

so the other side is 10.

the square 8 is 8*8

and square 6 is 6*6

so the other square is 10*10=100.

so the area of the blank square is 100.

Step-by-step explanation:
