Airida [17]

Answer: 55,811.91

Step-by-step explanation:

Given

Principal amount is 25,000

Time Period is t=15\ yr

Rate of interest r=5.5\%

Amount in compound interest is given by

\Rightarrow A=P\left(1+r\%\right)^t

Insert the values

\Rightarrow A=25,000(1+\dfrac{5.5}{100})^{15}\\\\\Rightarrow A=25,000(1.055)^{15}\\\Rightarrow A=55,811.91

You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed? 3x-2y=7 equati
svetlana [45]

Answer:

x = 31/9 and y = 5/3

Step-by-step explanation:

It is given that,

3x - 2y = 7  -----(1)

3x + 4y = 17 ----(2)

<u>To find the solution by elimination method</u>

Step 1: Subtract eq(2) from eq(1)

3x - 2y = 7  -----(1)

<u> 3x + 4y = 17 </u>----(2)

0  - 6y = -10

6y = 10

y = 10/6 = 5/3

Step 2: Substitute the value of y in eq (1)

  3x - 2y = 7  -----(1)

  3x  - 2*(5/3) = 7

  3x = 7 + 10/3

  3x = 31/3

   x = 31/9

Therefore x = 31/9 and y = 5/3

Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2 pounds of bananas
Anarel [89]
5x + 3y= 8.50
3x + 2y= 5.25

Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
