Answer:

x = 1/2

Step-by-step explanation:

(x + 2)2 + (9 - 3)2 = 4

2x + 4 + 18 - 6 = 4

2x + 16 = 4

2x = 4/16

2x = 1/4

x = 1/4/2

x = 2/4

x = 1/2

Answer:

We just need the equations to equal the same, which is y.

5+1.10x=y

3+1.50x=y

5+1.10x= 3+1.50x

Let's get x by itself by subtract 3 from both sides.

2+1.10x= 1.50x

Now subtract 1.10x from both sides.

2= 0.4x

Now divide each side by 0.4

5=X

So, at 5 games they're the same cost. Let's find the cost.

5+1.1(5)= 5+5.5=10.50

3+1.5(5)=3+7.5= 10.50

So, at 5 games, they are $10.50.

Hope this helps! :)

Jamal bought a diamond ring at a 20% discount. He paid $2640 for the ring. Naomi bought a similar ring but was given a discount

Fudgin [204]

Answer: 72%

Step-by-step explanation:

Set Jamal's original ring price = x

$x - x(0.2) = 2640\\x(1-0.2)=2640\\x(0.8)=2640\\x=\frac{2640}{0.8}=3300$

Jamal's original ring price = $3300

Set Naomi's discount = y

$3300-3300(y)=924\\=3300(1-y)=924\\1-y=\frac{924}{3300} \\-y=\frac{924}{3300} -1\\y=1-\frac{924}{3300}=1-0.28=0.72$

Naomi's discount is 0.72 = 72%

Use area formula (length x width)
42 x 25.5 = 1,071

Divide by total cost of wall paper

1,071/771.25 = $1.38 per square foot
