Answer:

-5

Step-by-step explanation:

The dot means multiply:  so 3 \cdot 2 = 3 \times 2 = 6

Also:  5² = 5 x 5 = 25

Therefore,

-6-4(3 \cdot 2)+5^2

\implies -6-4(6)+25

\implies -6-(4 \times 6)+25

\implies -6-24+25

\implies -5

- 6 - 4(3 \times 2) +  {5}^{2}

*Note:- The dot represents the multiplication symbol

\to - 6 - 4 \times 6 +  {5}^{2}

\to - 6 - 4 \times 6 + 25

\to- 6 - 24 + 25

\to - 30 + 25

\boxed{ \sf \: ans =  - 5}

Veronica is choosing between two health clubs after how many months will the total cost for each health club be the same
Assoli18 [71]

Question:

Veronica is choosing between two health clubs. after how many months will the total cost for each health club be the​ same? yoga studio a: membership: $24.00 monthly fee: 21.50. yoga studio b: membership: $41.00 monthly fee: $17.25

Answer:

It takes 4 years for the total cost of each club to become equal

Step-by-step explanation:

Given:

For yoga studio A:

membership: $24.00

monthly fee: 21.50.

For yoga studio B:

membership: $41.00

monthly fee: $17.25

To Find:

Number of months after which the total cost for each health club be the​ same = ?

Solution:

Let   x be the number of months of membership, and   y  be equal the total cost.

For Yoga club A

y = 21.50 x + 24

For Yoga club B    

y = 17.25 x + 41.00

we know that the prices,   y , would be equal, we can set the two equations equal to each other.

21.50 x + 24 =17.25 x+ 41.00

Grouping the like terms,

21.50x - 17.25 x= 41.00 -  24

4.25x=17

x=\frac{17}{4.25}

x = 4
