One antifreeze solution is 20% alcohol. Another antifreeze solution is 12% alcohol. How many liters of each solution should be c
katrin [286]
Use this systems of equations to solve:

x = first antifreeze
y = second antifreeze

\left \{ {{.2x + .12y = .18(15)} \atop {x + y = 15}} \right.

Isolate y.

x + y = 15
Subtract x from both sides.
y = -x + 15

Substitute y into the other equation.

.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25

Substitute x in the equation that we isolated y in.

y = -11.25 + 15
y = 3.75

11.25 L of the first antifreeze and 3.75 L of the second.

St. Augustine grass can grow at the rate of 4 over 7 centimeter per week.
kotegsom [21]

Given, the rate of growth of St. Augustine grass is \frac{4}{7} cm per week.

We have to find the number of weeks that the grass grow to \frac{12}{7} cm.

Let's take the number of weeks be x.

In 1 week the grass grow = \frac{4}{7} cm

So in x weeks the grass grow = (\frac{4}{7}) (x) =\frac{4x}{7} cm

So we can write,

\frac{4x}{7} =\frac{12}{7}

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,

(\frac{4x}{7}) (7) =(\frac{12}{7})(7)

4x =(\frac{12}{7})(7)

4x = 12

Now to get we will move 4 to the right side by dividing it to both sides. We will get,

\frac{4x}{4} =\frac{12}{4}

x = 3

So we have got the required answer.

After 3 weeks the grass grow \frac{12}{7} cm.

Point G is the centroid of triangle ABC. AG = (5x + 4) units and GF = (3x – 1) units. What is AF? 11 units 15 units 43 units 51
jek_recluse [69]

see the attached figure to better understand the problem

we know that

The point G is where all medians intersect and is often described as the triangle's center of gravity or centroid. It is formed by the intersection of the medians. The centroid divides each median in a ratio of \frac{2}{1}

so

\frac{AG}{GF}   =\frac{2}{1}  \\\\ \frac{5x+4}{3x-1}=\frac{2}{1}\\ \\ (3x-1)*2=5x+4\\ \\  6x-2=5x+4 \\\\ 6x-5x= 4+2\\\\ x=6\ units

<u>Find the value of FA</u>

FA=(5x+4)+(3x-1)\\ \\FA=8x+3\\ \\FA=8*6+3\\ \\FA=51 units

therefore

<u>the answer is </u>

51 units
