Answer:

x = 15 ounces

Step-by-step explanation:

A mixture is made with two types of solutions.

Solution A - 45 ounces of 10% saline solution

Solution B - x ounces of 70% saline solution

Resulting mixture - (x + 45) ounces of 25% saline solution

To get the value of x, equation will be,

(45 × 0.10) + (x × 0.70) = (x + 45) × 0.25

4.5 + 0.70x = 0.25x + 11.25

0.25x - 0.70x  = 4.5 - 11.25

-0.45x = -6.75

x = \frac{6.75}{0.45}

x = 15 ounces

Ian is going to water his plants is it reasonable to say he will fill the watering can with 3 liters of water explain
sveta [45]
This is possible for a smaller watering can. 3 liters is about 3/4 of a gallon (imagine a jug of milk).

It is equivalent to 3000 ml, which would also be 100 ounces of water.(5 -20 oz bottles of water).

What is the slope of the line that passes through the points (5,7) and (-1, 19) ?
Alexandra [31]

For this case we have that by definition, having two points through which a line passes (x_ {1}, y_ {1})\ and\ (x_ {2}, y_ {2}), we can find its slope of the following form:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

If we have:

(x_ {1}, y_ {1}) = (5,7)\\(x_ {2}, y_ {2}) = (- 1,19)\\m = \frac {19-7} {- 1-5}

We know that equal signs are added and the same sign is placed

m = \frac {12} {- 6}\\m = -2

So, the slope of that line is m = -2

Answer:

m = -2
