Step-by-step explanation:

6. The fraction can be written as;

$\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\$

Divide 4 by 2

= $\frac{2x^2}{y^3}$

The fraction can be written as;

$\frac{b^2}{6} /\frac{b}{a}$

introduce product sign as

$\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}$

The fraction can be written as;

$\frac{x}{y} /\frac{yx}{2}$

Introduce product sign

$\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}$

The fraction can be written as;

$\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}$

10.

The fraction is simplified to;

$\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}$

Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per r

ra1l [238]

Answer:

-1.5x + 70

Step-by-step explanation:

Total money he takes while going to the fair = $90

Money he spends to enter the fair = $5

Money he spends on food =$15

Total he spent now is given by

Now, he spend on rides at the fair i.e. 1.50 per ride .

Let the number of rides be x

So, cost incurred on rides = 1.5x

So, the spending money can be expressed as

Now, remaining money left to him after spending on x rides too is

Let f(x) denotes the function used to determine the money he has left over after rides .

So it becomes

f(x) = 70 - 1.50x

f (x) = -1.50x +70

Henry wants to buy a new table saw for his carpentry shop. He has saved $360 which is 2/3 of the price of the saw. How much does

Tema [17]

If 360 is 2/3 of the full price on a saw then your equation should look like this:

$360=\frac{2}{3} *x$

x is your unknown full price of the saw. Just solve for x now.

$360=\frac{2}{3} *x\\ \\ x=\frac{3}{2} *360=540$

This means that the full price is $540.

Hope this helps!

What is the midpoint of RS with endpoints R (-8, 3) and S (9, – 7)?

lubasha [3.4K]

Answer:

Midpoint coordinates are $(x,y) = (\frac{1}{2} , -2)$

Step-by-step explanation:

The Coordinates of R = (-8,3)

The Coordinates of S = (9, -7)

Let M be the mid point of M and its coordinates by (x,y)

Now, by mid point formula,

$(x,y) = (\frac{x_1 + x_2}{2} ,\frac{y_1 + y_2}{2} )$

⇒ $(x,y) = (\frac{1}{2} ,\frac{-4}{2} ) = (\frac{1}{2} , -2)$

So, the midpoint coordinates are $(x,y) = (\frac{1}{2} , -2)$
