Jenny’s mother is 5 years older than twice Jenny's age. The sum of their ages is 62 years. This is represented by the equation x

+ 2x + 5 = 62, where x is Jenny’s age. Plug in the values from the set {12, 15, 18, 19} to find the value of x. The value that holds true for the equation is . So, Jenny is years old and her mother is years old.

Answer:

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

1. Plug in the first value of the set

41 is different from 62, so Jenny isn´t 12 years old.

2. Plug in the second value of the set

50 is different from 62, so Jenny isn´t 15 years old.

3. Plug in the third value of the set

59 is different from 62, so Jenny isn´t 18 years old.

4. Plug in the fourth value of the set

Therefore Jenny´s 19 years old.

5. Calculate Jenny´s mother age:

As the sum of their ages is 62 ages, we have the following equation

where

x=Jenny´s age

y=Jenny´s mother age

Therefore Jenny's mother age is 43 years old.

Mario is setting up a new tent during a camping trip. The tent came with 7 feet of rope. The instructions are to use 34.5 inches
nevsk [136]

Answer: There are 6 sections of  8\frac{1}{4}\ inches  of rope Mario can cut from the rope .

Step-by-step explanation:

Since we have given that

Length of the rope for the tent = 7 feet

As we know that

1\ feet=12\ inches\\\\7\ feet=12\times 7=84\ inches

Length of rope is used to tie a tarp on top of the tent = 34.5 inches

Remaining length of rope is given by

84-34.5=49.5\ inches

According to question, the remaining rope should be cut into

8\frac{1}{4}\ inches\\\\=\frac{33}{4}\ inches

So, Number of  8\frac{1}{4}\ inches sections of rope Mario can cut from the rope is given by

\frac{49.5}{8\frac{1}{4}}\\\\=\frac{49.5}{\frac{33}{4}}\\\\=\frac{49.5\times 4}{33}\\\\=6

Hence, there are 6 sections of 8\frac{1}{4}\ inches rope Mario can cut from the rope .

Answer:  The correct table which represents relationship B is,

Time (min) 1 3 8 9

Temperature (°C) 54.2 59.0 71.0 73.4

Step-by-step explanation:

Since, It is given that, table represents Relationship A.

Time (min) 1 3 8 9

Temperature (°C) 53.6 58.4 70.4 72.8

And, According to the question,  Relationship B has a greater rate than Relationship A.

Therefore, for a particular time Relationship B must be given the greater value than relationship A.

Thus In 1 minute, The temperature by B > 53.6°

In 3 minutes, The temperature by relationship B> 58.4°

In 8 minutes, The temperature by relationship B> 70.4°

In 9 minutes, The temperature by relationship B> 72.8°

But when we apply this we found only Fourth table is following the above conditions.

Therefore, The table,

Time (min) 1 3 8 9

Temperature (°C) 54.2 59.0 71.0 73.4

represented by fourth option will be the correct table for relationship B.

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must
Nuetrik [128]

Let w be the amount of water that evaporates. At the start, the solution in the tub consists of 2.5 gallons of salt (5% of 50 gallons). After w gallons of water evaporates, we're left with a solution with total volume 50-w gallons, and 8% of this amount should be salt, or 0.08(50-w) gallons of salt. The amount of salt in the tank before and after evaporation remains unchanged, so

2.5=0.08(50-w)\implies2.5=4-0.08w\implies0.08w=1.5\implies\boxed{w=18.75}

gallons of water need to be evaporated.
