Leon needs $350
Leon has $130
Leon wants to save $20 per week
x = weeks

First, let's place what Leon needs on the left side of the equation:

$350 = ...

We know Leon as $130 saved so far, he plans to save $20 a week.
So, what you do here is add $130 to $20x. The reason why x is next to the $20 is because Leon wants to save $20 a week (the x represents the week). The reason why you add 130 is that's what Leon has saved so far. Therefore, the right side of your equation should look like this:

... = 130 + 20x

whereas 130 represents the amount saved so far, 20 represents weekly savings, x represents the number of weeks.

Put the left and right sides of the equation together and you should have:

$350 = $130 + $20x

Now, if you want to solve the equation:

Subtract 130 from both sides

  350 =  130 + 20x
- 130   - 130
-----------------------------
220 = 20x

Then, divide 20 by both sides

220 = 20x
-----   -----
20      20

11 = x

Leon needs to save up $20 for 11 weeks if he wants to buy the bike.

Want to check your answer?

Plug in 11 for x since 11 is the number of weeks.

350 = 130 + 20(11)
350 = 130 + 220
350 = 350

Answers match, therefore your answer is correct

Y=10x+100 what is the independent and dependent variable in this equation
valentina_108 [34]

Answer:

In this equation X is independent variable while Y is dependent variable.

Step-by-step explanation:

Equation:

Y=10x+100

Independent variable in math:

A variable in an equation that may have its value freely chosen without considering values of any other variable.

Dependent variable in math:

A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.

<u>According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.</u>

For example if x = 1, Y will be 110.

And if x = 10, Y will be 200.

*HELP PLEASE* How much money will Sarah have in her account if she deposits $2,700 and she invests in a simple interest savings
Rzqust [24]

Answer:

$3456

Step-by-step explanation:

We are given;

  • Money deposited (principle) as $2,700
  • Rate of interest is 3.5%
  • Time is 8 years

We are required to determine the amount that will remain after 8 years

  • We first need to determine the interest earned after eight years using the simple interest formula.

Simple interest = (Principle × rate × interest periods) ÷ 100

Therefore;

Interest = ($2,700 × 3.5% × 8 yrs)÷ 100

            = $756

Then determine the amount after 8 years

Amount = Principle + Interest

Therefore;

Amount = $2700 + $756

             = $3,456

Therefore, the money in the account after 8 years is $3456

What is 185% of 38?<br><br> 7.03<br><br> 70.3<br><br> 703<br><br> 7030
Lilit [14]

Answer:

B) 70.3

Step-by-step explanation:

You can solve this question two different ways.

One way is to find 85% of 38 by doing 38 × 0.85, which is 32.3. Then, you can add that to 38 (since 100% of 38 is 38) and get 70.3.

Another way you can find this (the easiest way) is to just find 185% right off the bat by doing 38 × 1.85 and get the answer of 70.3.
