A solution of salt and water contains 70 grams of water per 140 milliliters of the solution. If 1 mole of water weighs 16 grams,
Mama L [17]

Answer:

1.09 moles.

Step-by-step explanation:

There is 70g of water in 140ml of solution.

This means there are 17.5g of water in 35ml of solution. (Divide by 4)

In 17.5g of water, there are 17.5/16 = 1.09 moles of water.

Jamal wrote the inequality x/16 <6 . Which situation best represented by this inequality Helpppppp
Wittaler [7]

Given problem;

   Inequality equation;

               \frac{x}{16}   <   6

Before we solve, let us first translate this problem.

It simply states that for what value(s) of x will the expression be less than 6.

To find this value, we can simply carry out the normal mathematical simplification.

Simply multiply both sides by 16 to reduce the fraction;

      16  x (\frac{x}{16})   <  6 x 16

         

 On the left hand side, 16 will cancel out;

                   x <  96

Any value for which x is less than 96 will make the solution of this problem less than 6.

For example, 95;

                       \frac{95}{16}  = 5.93

This value is less than 6

Graph: 20x + 3.00y is greater than or equal to 500
hram777 [196]

Do you mind if I re-arrange it slightly before we solve it ?

         You said     20x  +  3.00y  ≥  500

Subtract  20x
from each side:               3.00 y  ≥  -20x + 500

Divide each side by  3 :          y  ≥  -20/3 x  +  500/3

Make it an equation,
and graph this line:                  y  =  -20/3 x  +  500/3

The line is made out of all points where 'y' is EQUAL to
1/3 of (-20x + 500).

The inequality wants to see all the points that are equal to it
AND all the points that are greater than that.

So the graph of the inequality is the line AND every point that's
anywhere above the line.  It's called the "half-infinite plane"
bounded by the line.
