If a student saves $35 per week how long will it take to save enough money to buy a computer

Answers

Answer:

How much does the computer cost?

Step-by-step explanation:

When you let me know I'll come back and help you with the answer :)

Tt will take [tex]$\frac{x}{35}[/tex] weeks to buy the computer

We have student who saves $35 per week.

We have to determine how many weeks will it take to save enough money to buy a computer.

If you save $30 per week, how much money you will save in 10 weeks ?

In 10 weeks you will save - 30 x 10 = $300

According to the question, we have -

Amount saved per week - $35

Assume that the cost of the computer is $x.

Now -

$35 → 1 week

$1 → [tex]$\frac{1}{35}[/tex] week

$x → [tex]$\frac{x}{35}[/tex] weeks.

Hence, it will take [tex]$\frac{x}{35}[/tex] weeks to buy the computer. You can put the cost of computer at the place of x and determine the number of weeks needed.

In the city where sonya lives, it rains and average of 8.05 centimeters each month last year.About how many centimeters of rain fell in all last year? Show your work.

Answers

In total it rained 96.6cm that year but on average it rained 100cm that year.
You would multiply 8.05 times the #of momths which is twelve.

The total centimeters of rainfall in the city for the past year where Sonia lives is given by the equation A = 96.6 cm

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total centimeters of rainfall for the past year be A

Now , the equation will be

The centimeters of rainfall every month in the city = 8.05 cm

The total number of months in a year = 12 months

So ,

The total centimeters of rainfall in the city for the past year A = centimeters of rainfall every month in the city x total number of months in a year

Substituting the values in the equation , we get

The total centimeters of rainfall in the city for the past year A = 8.05 x 12

On simplifying the equation , we get

The total centimeters of rainfall in the city for the past year A = 96.6 cm

Therefore , the value of A is 96.6 cm

Hence , the total rainfall is 96.6 cm

The value of y form the given equation is -65/11. Gabriela did mistake in second step while multiplying 12 and 5 and - sign into a bracket.

The given equation is 12(5+2y)=4y-(5-9y).

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

12(5+2y)=4y-(5-9y)

⇒ 60+24y=4y-5+9y

⇒ 60+24y=13y-5

⇒ 24y-13y=-5-60

⇒ 11y=-65

⇒ y=-65/11

Therefore, the value of y form the given equation is -65/11. Gabriela did mistake in second step while multiplying 12 and 5 and - sign into a bracket.
