Let X=the amount of water in the bucket. A bucket holds 2 2/3 gallons of water. The bucket is 5/6 full. How much water is in the bucket?

Answers

The answer is: 2 2/9 gal ; or, write as: 2.222 gal
________________________________________________
Explanation:
________________________________________________
(5/6) * (2 ⅔ ) = x ; Solve for "x"; which is our answer (in "gallons", or "gal").

_________________________________________________
→ Write "2 ⅔ " as an improper fraction;

→ 2 ⅔ = [(3*2) + 2 ] / 3 = (6+2) / 3 = 8/3 ;
________________________________________
→ Rewrite the problem, substituting "8/3" for "2 ⅔" ;
_______________________________________________
→ $(5)/(6)$ * $(8)/(3)$ ;

→ The "6" and the "8" can be reduced; since both the "6" and the "8" can be divided by "2"; → So change the "6" to a "3" ; (since "6÷2 = 3");
→ and change the "8" to a "4"; (since "8÷2 = 4") ;
_______________________________________________
→ and rewrite the equation as:
_____________________________________
→ $(5)/(3)$ * $(4)/(3)$ ;
______________________________________________
→ $(5)/(3)$ * $(4)/(3)$ =

$((5*4))/((3*3))$ =
___________________________________________
→ $(20)/(9)$ gallons =

→ 20 ÷ 9 =
_________________________________________

→ 2 2/9 gal ; or, write as: 2.222 gal

9a-5a for a=7 what is the answer

Answers

Hi there!

To solve your answer, since we know a = 7, we can easily solve your equation.

But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.

When you have a number, and a variable attached to it, it means to multiply.

Now, to make this equation look a little easier, lets rewrite it.

9 × 7 - 5 × 7 = ___

According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.

9 × 7 = 63.

5 × 7 = 35.

Now, since we've multiplied the two numbers, its time to subtract them.

63 - 35 = 28. Sooooo........

9 × 7 - 5 × 7 = 28

Hope this helps!

Message me if you need anything else, I'd be happy to help you out! :D

the answer is 28
when a number is attached by a variable, that usually means that it is attached by multiplication so, i multiplied 9 times 7 and got 63 then i multiplied 5 times 7 and got 35 then subtract 63 and 35 and i got 28
i hope this helps :)

0.985 rounded to the nearest tenth

Answers

They always try to trick you with this. Remember anything 5 or above would round up, anything 4 and under would round down. So look for the tenth place. that's the 9. The number to the right is 8 which is greater than 5. That means round up. You can't round it to 0.1 because that takes it back down. So you just move it over. The answer is 1.0.

What does prime fractorization

Answers

Math Term Definition. Prime factorization. Prime factorization is finding the factors of a number that are all prime. Here's how you do it: Find 2 factors of your number. Then look at your 2 factors and determine if one or both of them is not prime.

Prime factorization is finding which prime numbers can be multiplied to get the number that they give you originally E.J. if they give you 24 and find 2 numbers that factor it the first that would come to mind would be 12 times 2 well 2 can't be simplified no more but 12 can, 12 can have factors of 3 and 4, now 3 cant be factored but 4 can, 4 can be multiplied by 2 times 2... so now that you factored it completely you know that 2*2*2*3=24. lets check it out 2 times 2 is 4 4 times 2 is 8 and 8 times 3 is 24. this means our factors are correct!!!

Hope this helps
