Explicación paso a paso:

Edad de Eva = x

Edad de Ana = x - 12

Dentro de los 7 años de la edad de Eva, la edad de Ana será el doble

x + 7 = 2 (x - 12 + 7)

x + 7 = 2 (x - 5)

x + 7 = 2x - 10

x - 2x = - 10 - 7

-x = - 17

x = 17

Por lo tanto, Eva tiene 17 años.

Answer:

The correct answer is B) 18%

Step-by-step explanation:

Note that the vaccine is already and is 80% effective. This means that if the entire population was administered with the vaccine, only 8/10 would gain immunity leaving 2/10 or 0.2 exposed.

If the new vaccine, therefore, is supposed to be 90% effective, it is only pragmatic to administer it against those who do not have immunity which is 0.2 of the existing population.

So to get the percentage that will develop immunity, we have:

0.2 x 0.9 = 0.18 or 18%

Cheers!

Answer:

x=−6

x=2

Step-by-step explanation:

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.

∣x+2∣−5=−1

Add 5 to both sides of the equation.

∣x+2∣=4

Use the definition of absolute value.

x+2=4

x+2=−4

Subtract 2 from both sides of the equation.

x=2

x=−6

Answer:

C. $2.04

Step-by-step explanation:

Because we see that 5.2 pounds is $5.29, roughly around 5.2, we can infer that 2 pounds of rice would equal just a little bit over $2, and the only logical answer would be $2.04.

Hope this helps you have a good day!

Answer:

1. x>-1

2. x<4

3. x<-1

4. x>-2

5. x<-3

6. x<7

Step-by-step explanation:

1. 2x>-2  Divide both sides by 2.

  /2   /2

x>-1

2. 4x<16  Divide both sides by 4.

   /4   /4

x<4

3. x+4<3 Subtract both sides by 4.

      -4  -4

x<-1

4. 5x>-10  Divide both sides by 5.

  /5     /5

x>-2

5. 3x<-9   Divide both sides by 3.

   /3   /3

x<-3

6. x-4<3  Add 4 to both sides.

    +4 +4

x<7

Hope this helps you out...next time, try to figure it out yourself without asking a lot of questions. By looking at one example, you can probably apply what to do for the other inequalities.

Answer:

The family will need to purchase 187 square ft carpeting.

Step-by-step explanation:

Area of Rectangles

Given a rectangle with width W and length H, the area is calculated as follows:

A = W * H

The new carpet of the family has the shape provided in the figure. We have completed the shape to add some missing dimensions by adding and subtracting the given lengths. Please refer to the attached image.

The total area of the carpet is the sum of the areas of three rectangles.

The rectangle at the bottom has dimensions 3 ft x 20 ft, thus its area is:

A1 = 3 ft * 20 ft = 60 square ft

The rectangle at the middle has dimensions 3 ft x 17 ft, thus its area is:

A2 = 3 ft * 17 ft = 51 square ft

The rectangle at the top has dimensions 4 ft x 19 ft, thus its area is:

A3 = 4 ft * 19 ft = 76 square ft

The total area of the carpet is:

A = 60 square ft + 51 square ft + 76 square ft

A = 187 square ft

The family will need to purchase 187 square ft carpeting.

Answer:

40

Step-by-step explanation:

The parallelograms are similar, so their corresponding sides are proportional.  Write a proportion:

12 / 30 = 16 / PQ

Cross multiply:

12 PQ = 480

Solve for PQ:

PQ = 40

Answer:

A) 4x+12y

B) 2(2x+6y) is one way to do it

Step-by-step explanation:

[tex] \text{8x - 4 - 6x + 9}[/tex]

First, combine like terms :

Like terms are those which have the same base.

[tex] \longrightarrow{ \sf{8x - 6x - 4 + 9}}[/tex]

[tex] \longrightarrow{ \sf{2x - 4 + 9}}[/tex]

Remember : The negative and positive integers are always subtracted but posses the sign of the bigger integer.

[tex] \longrightarrow{ \boxed{ \sf{2x + 5}}}[/tex]

And we're done!

Hope I helped!
