What is the solution of |x|=19

A savings account grows by 3% each year. Sofia places $500 in the account at the beginning of the year. (a) How much does Sofia

seraphim [82]

Answer:

a) $515

b) $530.45

c) The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Step-by-step explanation:

a)

After one year, the amount increased is 3% of the inicial value, so it is 0.03 * 500 = $15

So Sofia has 500 + 15 = $515 at the end of the year.

b)

After the second year, the amount will increase by 3%, but now the amount is 515, so we have 0.03 * 515 = $15.45

So Sofia has 515 + 15.45 = 530.45 at the end of the second year.

c)

The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.

Is the number of total molecules on the left side of a balanced equation always equal to the number of total molecules on the ri

gulaghasi [49]

Since no reaction creates or destroys atoms, every balanced chemical equation must have equal numbers of atoms of each element on each side of the equation. However, the number of molecules does not necessarily have to be the same.

The answer is

No, the total number of molecules can be equal or not

<h2>Question</h2>

Simplify the following

A . ( 12 ) x ( − 16 ) + 16

b . ( − 34 ) ÷ ( − 23 ) + 14

c . ( − 45 ) ÷ ( − 15 ) + 13

d . ( 23 ) - ( − 16 ) - 13

e . ( − 42 ) + ( - 16 ) ÷ 13

<h2>Answer:</h2>

(A) -176

(B) $\frac{402}{23}$

(C) 16

(D) 26

(E) $\frac{-562}{13}$

<h2>Step-by-step explanation:</h2>

(A)

( 12 ) x ( − 16 ) + 16

Following the rules of BODMAS

=> Solve the brackets first

12 x -16 + 16

=> Next, solve the multiplication(x)

-192 + 16

=> Solve the addition and subtraction

-176

(B)

( − 34 ) ÷ ( − 23 ) + 14

Following the rules of BODMAS

=> Solve the brackets first

-34 ÷ -23 + 14

=> Next, solve the division(÷)

$\frac{-34}{-23}$ + 16

The negative signs can cancel out.

$\frac{34}{23}$ + 16

=> Solve the fraction

$\frac{34}{23}$ + $\frac{16}{1}$

$\frac{34 + 368}{23}$

$\frac{402}{23}$

(C)

( − 45 ) ÷ ( − 15 ) + 13

Following the rules of BODMAS

=> Solve the brackets first

-45 ÷ -15 + 13

=> Next, solve the division(÷)

$\frac{-45}{-15}$ + 13

The negative signs can cancel out.

$\frac{45}{15}$ + 13

3 + 13

=> Solve the addition

3 + 13 = 16

(D)

( 23 ) - ( − 16 ) - 13

Following the rules of BODMAS

=> Solve the brackets first

23 - -16 - 13

=> Next, - - will give +

23 + 16 - 13

=> Next solve the addition

39 - 13

=> Next solve the subtraction

39 -13 = 26

(E)

( − 42 ) + ( - 16 ) ÷ 13

Following the rules of BODMAS

=> Solve the brackets first

-42 + -16 ÷ 13

=> Next, + - will give -

-42 - 16 ÷ 13

=> Next solve the division

-42 - 16 ÷ 13

-42 - $\frac{16}{13}$

=> Next solve the fraction

$\frac{-42}{1}$ - $\frac{16}{13}$

$\frac{-546-16}{13}$

$\frac{-562}{13}$
