Remember you can do anything to an equation or inequality as long as ou do it to both sides
also, when multiplying by a negative number in an inequality, don't forget to flip the sign

5+5(x+4)<20
minus 5 from both sides
5(x+4)<15
divide both sides by 5
x+4<3
minus 4 from both sides
x<-1

Question 1 of 10 Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What
dangina [55]

Hey there!!

The question states that a sum is invested which is $3000 and hence, this would be counted as the principle amount or the principle sum.

The term given is 3 years, which gives us the idea that this interest is being counted or being active for 3 years.

She ( Diana ) earned the sum $450 at the end of three years. This means, the simple interest is $450.

Never get confused with the principle amount, principle sum and interest.

<u><em>Principle amount = Principle sum + The interest. </em></u>

Formula given :

I = prt

'p' is denoted as the principle sum, r is the rate and the t is the term or the number of years.

Now, plugging in all the values :

... <em>450 = 3000×r×3 </em>

... <em>450 = 9000×r </em>

... <em>r = 450 / 9000</em>

... <em>r = 0.05 </em>

... <em>r = 5% </em>

As we need the answer in the decimal form, the answer would be <em><u>0.05</u></em>

Hope my answer helps!!<em> </em>

T=pd/2x<br><br><br><br>solve for X<br><br>i always get confused when theirs more then one letter
Ainat [17]
When there's more than one letter, and you just have to solve for one variable, you can just solve it like you would any other equation. Treat the other variables like numbers and add, subtract, multiply, and divide them to both sides of the equation in order to isolate the variable you want to solve for.

t= \frac{pd}{2x}  \\  \\ t*2x= \frac{pd}{2x}*2x \\  \\ 2tx=pd \\  \\  \frac{2tx}{2t} = \frac{pd}{2t}  \\  \\ x=\frac{pd}{2t}
