Taking x as the number to be found,
x=32a+30=58b+44 where a and b are the quotients you get on dividing x by 32 and 58.
Simplifying this equation you get 16a+15=29b+22
16a= (16+13)b+22-15 or 16a=16b+13b+7
16(a-b)=13b+7
Now I have to find a value for b where 13b+7 is divisible by 16. The least common multiple of these numbers can be found by going through the multiplication tables of 13 and 16 and 13x13+7=176, while 16x11 is also 176.
Now that the value of b is found to be 13, we can substitute it in our first equation, x=58b+44=58x13+44=798.
Now find the least common multiple of 58 and 32
LCM (n,m)=nm/GCD (n,m) where GCD is the greatest common divisor of n and m
LCM (58, 32)=58x32/2 as 2 is the GCD of 58 and 32
LCM (58, 32)= 1856/2= <em>928</em>
Add this LCM to the previous answer, ie, 798 to get the next answer in the series. 798+928=1726
Add the LCM again to the last answer to get the final answer, that is less than 3000=1726+928=2654

The amount of orange juice in a bottle is modeled by the equation y=128-8x, where y is the number of ounces of juice in the bott
Fantom [35]

Answer:

Number of servings left is bottle = 128-9x

Step-by-step explanation:

The amount of orange juice in a bottle is modeled by the equation

y=128-8x ---Eq (1)

Here y = number of ounces of juice in the bottle

and x = number of servings of juice poured from the bottle

Number of servings left is bottle =  number of ounces of juice in the bottle -number of servings of juice poured from the bottle

Thus,

Number of servings left is bottle =  y -x

Substracting x from both the sides of the above equation, we get - y-x = 128-8x-x\\y-x = 128-9x

Number of servings left is bottle = 128-9x

Can someone please help with this question of what the explicit rule is.
Lyrx [107]

Answer:

f(n)=-6n+36

Step-by-step explanation:

The sequence is arithmetic because it is going down/up by the same number each time.

It is going down by 6.

This tells us that the common difference is -6.

The first term is 30.

The following is the explicit form of an arithmetic sequence:

f(n)=f(1)+d(n-1)

where f(1) is the first term and d is the common difference.

So we have f(1)=30 and d=-6.

Plugging this information into our explicit formula:

f(n)=30+-6(n-1)

f(n)=30-6n+6

f(n)=30+6-6n

f(n)=36-6n

f(n)=-6n+36

Let's check it.

The first term is f(1)=30:

f(1)=-6(1)+36=-6+36=30 which is what the pattern reads for the first term.

The second term is f(2)=24:

f(1)=-6(2)+36=-12+36=24 which is what the pattern reads for the second term.

The third term is f(3)=18:

f(3)=-6(3)+36=-18+36=18 which is what the pattern reads for the third term.

The fourth term is f(4)=12:

f(4)=-6(4)+36=-24+36=12 which is what the pattern reads for the fourth term.

This rule certainly does generate the terms of our sequence as we have shown above.

The explicit form with no doubt is f(n)=-6n+36.
