Answer:

$\huge\boxed{j=45}$

Step-by-step explanation:

$-2j=-90\qquad|\text{divide both sides by (-2)}\\\\\dfrac{-2j}{-2}=\dfrac{-90}{-2}\qquad|\text{we know}\ \dfrac{(-)}{(-)}\to(+)\\\\\dfrac{2\!\!\!\!\diagup j}{2\!\!\!\!\diagup}=\dfrac{90}{2}\\\\j=45$

Here are two rectangles.

creativ13 [48]

Answer:

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}$

Step-by-step explanation:

Let the length of rectangle A be x units.

So, length of rectangle B

= x + 25% of x

= x + 0.25x

= 1.25x

Let the width of rectangle A be y units

So, Width of rectangle B

$= \frac{3}{5}\times x\\=0.6x$

Area of rectangle A = xy

Area of rectangle B

= 1.25x * 0.6y

= 0.75xy

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\$

Y=−2x+1<br> x−3y=11 find the solution using elimination.

yawa3891 [41]

Answer:

Step-by-step explanation:

Using first equation in the second gives you

x-3(-2x+1)=11

x+6x-3=11

7x-3=11

7x=14

x=2, making y=-2x+1 become

y=-2(2)+1

y=-4+1

y=-3 so the solution is the point

This expression represents the average cost per game, in dollars, at a bowling alley, where n represents the number of games:

Dmitry_Shevchenko [17]

Answer:

Average Cost per game for 4 games is:

A) $4.75

Step-by-step explanation:

As the question is not complete, lets complete it first.

At the bowling Alley, shoe rentals cost $3 while a games costs $3. The expression that represents the average costs per game 'c' , in dollars, where n is the number of games, is:

$c=\frac{4n+3}{n}$

To find average cost per game, for 4 games, simpli substitute n=4 into the given equation:

$c=\frac{4n+3}{n}\\c=\frac{4(4)+3}{4}\\c=\frac{16+3}{4}\\c = \frac{19}{4}\\c= 4.75$

So Average Cost per game for 4 games is:

c = 4.75$
