Step-by-step explanation:
si sna es 12 años menor que eva y dentro de 7 años la edad de eva es el doble que la edad de ana que edad tiene eva
Responder:
17
Explicación paso a paso:
Dejar ;
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 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.

Henry needs a 16 ft. table for his family dinner. He is going to put two tables together. He has an 8ft table. How long does the other need to be?
Answer:
The other table needs to be 8ft long as well.

To get to 16ft, we need to subtract the 8ft that Henry already has.
16 - 8 equals 8.
So, the other table needs to be 8 feet.

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

A vaccine, which is currently in use, is known to be 80% effective. A pharmaceutical company has developed a newvaccine and the company claims that 90% of the people given the new vaccine will develop the immunity. Supposethe claim of the company is true, and the newly developed vaccine is given to 20 people. The expected number of people in the sample that will develop the immunity is:__________ a) 90% b) 18% c) 16% d) 80%
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%

Level 3
Solve: |x + 2|– 5 = -1
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

Denise bought 5.2 pounds of rice for $5.29. Using the unit rate, how much would 2 pounds of rice cost? A $1.02 C $2.04 B $1.29 D $6.31
Answer:
it's A
Step-by-step explanation:
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.
