Ok so the amounts are x and 100-x

0.24x+0.5(100-x)=0.36(100)
solve
0.24x+50-0.5x=36
-0.26x+50=36
mminus 36 both sides
-0.26x=-14
divide both sides by -0.26
x=53.8462

find other one
100-x=100-53.8462=46.1538


53.8462 gallons of the 24%
46.1538 gallons of the 50%

Question 1
777dan777 [17]

Answer:

There would be 94 tiles.

Step-by-step explanation:

The number of tiles is given by the following equation:

n = 6 + 4p

In which p is the current position.

How many tiles would there be in position 22?

This is n when p = 22. So

n = 6 + 4*22 = 6 + 88 = 94

There would be 94 tiles.

jasenka [17]

Answer:

x-0.33x  = 0.67x

Step-by-step explanation:

Given :  A new soup recipe contains 33% less sodium per serving than the old soup recipe.

The old soup recipe contained x milligrams of sodium per serving.

To Find: Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe

Solution :

Since we are given that old recipe contains x milligrams of sodium per serving

And new recipe  contains 33% less sodium per serving than the old soup recipe.

So, 33%of x = 0.33x

Since new recipe contains 33% less sodium than old recipe:

⇒x-0.33x

or

⇒(1-0.33)x

⇒0.67x

Thus expressions which could represent the amount of sodium per serving, in milligrams, in the new soup recipe :

x-0.33x or 0.67x
