Answer

So im not sure but I think that the answer is x=0.08y-0.18

Step-by-step explanation: Solve for x by simplefying both sides of the equation, then isolating the variable.

PLEASE HELP ME WITH BOTH OF THESE PROBLEMS THIS IS DUE SOON PLEASE HELP ME

iogann1982 [59]

Answer:

Step-by-step explanation:

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

4Comic+1 Nonfiction

4comic = 8y so 1 comic = 2y

1 nonfiction = (3+7y)+ 2y

1 nonfiction = 7y+2y+3 = 9y+3

total= 8y+9y+3 = 17y+3

if y=4

total = 17*4 +3 = $71

Log10 (2x + 1) - logio(3x - 2) = 1

Pavlova-9 [17]

Answer: x=3/4

Step-by-step explanation:

To solve, first express the left side as one logarithm. To do so, apply the quotient rule which is log_bM/N=log_bM-log_bN .

log((2x+1)/(3x-2))=1

Then, express the equation to its equivalent exponential form to eliminate the logarithm.

Note that the exponential form of log_b M=a is M=b^a .

Since the base of the logarithm in the given equation is not written, it indicates that its base is 10.

So re-writing the equation, it becomes:

log_10((2x+1)/(3x-2))=1

And its exponential form is:

(2x+1)/(3x-2)=10^1

(2x+1)/(3x-2)=10

Now that the equation has no more logarithm, the next step is to remove the x in the denominator.

To do so, multiply both sides by 3x-2.

(3x-2)*(2x+1)/(3x-2)=10*(3x-2)

2x+1=30x-20

Next, combine like terms.

To combine 30x and 2x, bring them together on one side of the equation. So, move 2x to the right side by subtracting both sides by 2x.

2x-2x+1=30x-2x-20

1=28x-20

To combine 20 and 1, bring them together on the side opposite the term with x. So, add both sides by 20.

1+20=28x-20+20

21=28x

And, divide both sides by 28 to have x only at the right side.

21/28=(28x)/28

3/4=x

Hence, the solution to the given equation is x=3/4 .

1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar

Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

En el sistema de ecuaciones, tiene-se que los números son x e y.
Suma de 115, o sea, $x + y = 115$
El número mayor es dos veces más 22 unidades que el otro, o sea, $x = 2y + 22$

----------------

Primero se encuenta el número menor, reemplazando la segunda ecuación en la primera:

$x + y = 115$

$2y + 22 + y = 115$

$3y = 93$

$y = \frac{93}{3}$

$y = 31$

----------------

El número mayor es dado en función de el menor, o sea:

$x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84$

Los números son 31 y 84.

A chord divides a circle into

Pani-rosa [81]

A chord divides a circle into 2 segments.

A major segment and a minor segment.

If the chord passes through the center of the circle, then it divides the circle into equal segments.
