**Answer:**

So here is the answer to your question by using the formulae of compound amount.

Initial price( P) = $5000

Interest rate( R) = 2% pa

Time ( T) = 30 years

Compound amount (CA)=?

We have

CA=P(1+R/100)^T

=5000(1+2/100)^30

=$9056.807921

Use the zero product property to find the solutions to the equation x2 â€"" 15x â€"" 100 = 0. X = â€""20 or x = 5 x = â€""20 or x = â€""5 x = â€""5 or x = 20 x = 5 or x = 20.

The **values **for [tex]x[/tex] are** -5 and 20**

Given to us:

[tex]x^2-15x-100=0[/tex]

In order to use the **zero product property**, we need to find out a 2 numbers whose **product **is -100 and **sum **is -15.

for that you can take the **LCM **of 100 and check all **factors **of 100.

for example,

factors of 100 are 100, 50, 25, 20, 10, 5, 4, 2, 1.

from this **-20 **and **+5** are the numbers whose sum will give -15 and product will be -100. therefore,

[tex]x^2-15x-100=0\\x^2-20x+5x-100=0[/tex]

taking out **common terms**, we get

[tex](x^2-20x)+(5x-100)=0\\x(x-20)+5(x-20)=0\\(x+5)(x-20)=0\\[/tex]

to find out the value of [tex]x[/tex] **equating **both the **factors **with 0, we get

MEDIUM) Ana gave Bill and Clare as much money as each had. Then Bill gave Ana and Clare as much money as each had. Then Clare gave Ana and Bill as much money as each had. Then each of the three people had $24. How much money did each have to begin with

**Answer:**

**At the very end, the amounts of money are:**

**A -- 24**

**B -- 24**

**C -- 24**

**If A and B received as much as they had just prior to the last transaction, they must each have received 12 and they must have received it from C, so at the end of the previous step, the situation must have been:**

**A -- 12 (24 minus 12)**

**B -- 12 (24 minus 12)**

**C -- 48 (24 plus 12 plus 12)**

**Before that, A and C got half of what they had above from B, so:**

**A -- 6 (12 minus 6)**

**B -- 42 (12 plus 6 plus 24)**

**C -- 24 (48 minus 24)**

**And initially, B and C got half of what they had above from A, so:**

**A -- 39 (6 plus 21 plus 12)**

**B -- 21 (42 minus 21)**

**C -- 12 (24 minus 12)**

In the figure below, m∠1 = x and m∠2 = x - 4. Which statement could be used to prove that x = 47?

A) m∠1 = m∠2

B) m∠2 = 47

C) m∠1 + m∠2 = 90

D) m∠1 + m∠2 = 180

**The answer is C) m∠1 + m∠2 = 90**

**Explanation: So ∠1 is x and ∠2 is x-4**

**Basically you know than ∠3 is 90° ... And a straight line is 180° .. So technically we can just find out 180-90 is 90(the other angle 1 + 2).**

**To get 90° we'll add ∠1 and ∠2 in other ways, like technical thinking-**

**So you already know adding ∠1 and ∠2 is 90°. So ∠1 + ∠2 = 90°**

**In other words you can say m∠1 + m∠2 = 90 **

If 3 cans of beans cost 90¢, how many can you buy for $2.70?

If you can buy 10 juice packs for $3.00, how much will you spend to buy 4 juice packs?

please answer asap

9 cans of beans and spend around 13.25 dollars

**Answer:**

**Step-by-step explanation:**

1. 3 cans cost 90 cents

3=0.90 & x=2.7

by ratio:

3/0.9 = x/2.7

0.9x=8.1

x= 9

**So you can buy 9 cans for 2.7 dollars**

2. 10 Juice cost 3 dollars

by ratio:

10/3 = 4/x

10x=12

x=1.2

Set up a proportion with the known values and solve for the part.

Using whole = $25, percent = 15%, part = ? dollars

part whole=percent 100→?25=15100

Jeremiah is taking two of his friends out for pancakes. If he spends $17.55 on their meals and has $26 to spend in total, Jeremiah’s pancakes must cost no more than what amount?

Inequality Question

**Answer:**

$8.45

**Step-by-step explanation:**

if he has $26 to start and spends 17.55 on his friends, he has 8.45 leftover to spend on himself, but since he bought his friends pancakes for 17.55 their pancakes would have cost 8.775 each which suggests that Jeremiah likely cannot afford his own pancakes

Solve 2(x - 5) + 11 = 17

Show how you got your answer(s).

Are either of your answer extraneous yes or no. Justify your response

**Answer:**

x=8 and is not extraneous

**Step-by-step explanation:**

2(x-5)+11=17

2x-10+11=17

2x+1=17

2x=17-1

2x=16

x=8

extraneous means it is a solution, but it is not possible in the equation, to determine if it is extraneous, plug it in to the original equation

2(8-5)+11=17

2(3)+11=17

6+11=17

17=17

since it works in the orignial equation it is not extraneous

The **solution **to the **equation** 2(x - 5) + 11 = 17 is x = 8

From the question, we have the following parameters that can be used in our computation:

2(x - 5) + 11 = 17

When the **like terms **are **evaluated**, we have

2(x - 5) = 6

**Divide **through the equation by 2

x - 5 = 3

So, we have

x = 3 + 5

Evaluate

x = 8

Hence, the **solution **to the **equation** is x = 8
