oksano4ka [1.4K]

Answer:

52 and  38

Step-by-step explanation:

If x = 13 then 4x = 4 * 13 so 52.  

Same for the next one.  2x = 2 * 13 so 26.  26+12 is 38.

Find the percent of change <br><br> a: 1/3 to 2/3<br><br> b: 1/3 to 1/6<br><br> please help!
Dimas [21]

Answer:

a: The percentage change from 1/3 to 2/3 is 100 %

b: The percentage change from 1/3 to 1/6 is 0 %

Step-by-step explanation:

use this formula:

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((2/3 - 1/3) / 1/3) * 100 = 100 %

_________________________________

((y2 - y1) / y1)*100 = your percentage change

(where y1=start value and y2=end value)

((1/6 - 1/3) / 1/3) * 100 = 0 %

Using an infinite geometric series for the repeating decimal 0.551¯¯¯¯¯¯¯¯, with ratio 11000, find integers a and b so that 0.55
irga5000 [103]

Answer:

Sum = 551/999

Where a = 551 and b = 999

The two integers are 551 and 999

Step-by-step explanation:

Given

Decimal = 0.551

Ratio = 1/1000

By repeating the decimal, we can write;

0.551 -bar = 0.551551551.....

0.551551551..... = 0.551 + 0.000551 + 0.000000551 + ....

= 551/1000 + 551/1000000 + 551/1000000000 + ......

= 551/10³ + 551/10^6 + 551/10^9 + .....

= n=0 Σ∝(551/10³)(1/10³)^n

Hence, the infinite geometrc series is Σ(551/10³)(1/10³)^n for n = 0 to

∝

Given the ratio of 1/1000

Let r = 1/1000

r = 1/10³

a = 551/10³

The sum is defined as follows;

a/(1-r)

Sum = 551/10³ / (1 - 1/10³)

Sum = 551/1000 ÷ 999/1000

Sum = 551/999

So, a/b = 551/999

Where a = 551 and b = 999

The two integers are 551 and 999

Solve the system of linear equations: 1/5 x + 1/8 y = 1 1/2 x − 1/3 y = 1
Alchen [17]

Answer:

x = 75 and y = -72

Step-by-step explanation:

It is given that,

1/5 x + 1/8 y = 1   ------(1)

1/2 x − 1/3 y = 1  -------(2)

<u>To find the solutions of the system of equations</u>

Step 1: eq(1) * 5 ⇒

x + 5/8y = 5  ----(3)

Step 2:  eq(2) * 2 ⇒

x - 2/3y = 2  -----(4)

Step 3: eq(3) - eq(4) ⇒

x + 5/8y = 5  ----(3)

<u>x - 2/3y = 2  -</u>----(4)

0 +(5/8 - 2/3)y = 3

 -1/24 y = 3

y = -24*3 = -72

Step 4: Substitute the value of y in eq(1)

1/5 x + 1/8 y = 1   ------(1)

1/5 x + 1/8 (-72) = 1   ------(1)

1/5 x  - 24 = 1

1/5 x = 25

x = 5*25 = 75

Therefor x = 75 and y = -72

What is NOT the value for p? (Multiple Answers)<br> 9<br> 8<br> 6<br> 7
solmaris [256]

The definite value for p is 9.

But how are 8, 7, or 6 the value of p?

I personally think that you should contact the teacher who made this question. He/She probably meant to say What IS the value for p?

You use algebra to get the value for p:

20p-45 = 9p + 5p

Start solving from there.
