5/9 + 1/3 + tuna = 1

tuna =   1  - 5/9 - 1/3.           LCM = 9

tuna = 9/9 - 5/9 - 3/9 = (9 - 5 - 3)/9 = 1/9

Fraction of tuna = 1/9

Let all the puffs be x.   Recall there are 18 tuna

(1/9)x = 18

x/9 = 18

x = 9*18

x = 162

There are 162 puffs in all.

Let n be the total number of puffs. Now we can write:
n=\frac{5}{9}n+\frac{1}{3}n+18
Adding the fractional value of n, we get:
n=\frac{5+3}{9}n+18
Simplifying and rearranging gives us:
n-\frac{8}{9}n=18
Therefore we can simplify to get:
\frac{1}{9}n=18
and finally
n=18\times9=?
The fraction of the puff that are tuna is found from:
\frac{18}{18\times9}=\frac{1}{9}

-70y^2+90x^3+100yx^2-63xy<br>factor by grouping
Alexeev081 [22]
The idea of grouping is to get the terms in groups that allow you to factor out from each group something that becomes a factor in itself, leaving two factors behind that are alike. Like this: rearrange those terms so they are in this order:
(-70y^2 - 63xy) + (90x^3 + 100yx^2).  Now out of the first set we are going to factor out a -7y, and out of the second set we are going to factor out a 10x^2. When we do this, this is what we get: -7y(10y + 9x) + 10x^2(9x + 10y). As you can see, what's inside both sets of parenthesis is the same, just in a different order. We can factor that out now, leaving (9x + 10y)(10x^2 - 7y). And that is factored by grouping.

What is the answer to this equation: 7.4 - 9 - 2r =18
lorasvet [3.4K]

We can get the answer to this equation by solving for the variable (r).


7.4 - 9 - 2r = 18


We want to get r on one side, so we want to push everything else to the other side.


-2r = 18 - 7.4 + 9


-2r = 19.6


2r = -19.6


r = -9.8
