Answer:

77

Step-by-step explanation

Assuming a, b, and c are all natural numbers:

First, set b equal to each other in each ratio

a : b = 3 : 8 = 9 : 24

b : c = 6 : 11 = 24 : 44

You have your smallest values for a, b, and c: 9, 24, 44

Adding them yields 77

Answer:

77

Step-by-step explanation:

b is present in both ratios, find first the LCM of 8 and 6, which is 24.

Multiply a:b=3:8 by 3 to get a:b=9:24

Similarly, multiply b:c=6:11 by 4 to get b:c=24:44

Then we conclude

a:b:c=9:24:44

Since there is no common factor among the three numbers, this is the simplest ratio possible.

If a,b and c are integers, the smallest values for a,b and c are 9,24,44.

Add up the three numbers to get the least value of a+b+c=77.

Simplify (9x-1)^-1/2 - (x+2)(9x-1)^-1/2
iren2701 [21]

Answer:

Step-by-step explanation:

(9x-1)^-1/2 - (x+2)(9x-1)^-1/2

= (9x-1)^-1/2( 1 - (x + 2))

= (9x-1)^-1/2(-1 - x)

= -(x + 1)(9x-1)^-1/2

= -(x + 1) / (9x-1)^1/2

F(X)=3x-12 what is f(2)
Vinil7 [7]

Answer:

<h3>The answer is - 6</h3>

Step-by-step explanation:

f(X)=3x-12

To find f(2) substitute the value in the bracket which is 2 into f(x)

That's

f(2) = 3(2) - 12

= 6 - 12

= - 6

Hope this helps you

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?
morpeh [17]

Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

Whats the greatest ten you can multiply by 19 to get close to but not go over 684
USPshnik [31]

Answer:

The desired expression is  19 x (3 tens) = 19  x 30 = 570

So, the greatest ten   = 3 (tens)

Step-by-step explanation:

Let us check each tens.

19 x (1 ten)   = 19 x 10  = 190

19 x (2 tens) = 19 x 20  = 380

19 x (3 tens) = 19  x 30 = 570

19 x (4 tens)  = 19 x 40  =  760

But, here 760 is OVER the given term 684.

and 570 is the nearest value to the value 684.

So, the desired expression is  19 x (3 tens) = 19  x 30 = 570
