Answer:

\large\boxed{x=3\dfrac{3}{4}}

Step-by-step explanation:

\dfrac{3}{4x}=\dfrac{1}{5}\qquad\text{cross multiply}\\\\(4x)(1)=(3)(5)\\\\4x=15\qquad\text{divide both sides by 4}\\\\x=\dfrac{15}{4}\\\\x=3\dfrac{3}{4}

Brianna bought snacks for her team's practice. She bought a bag of oranges for $2.72 and a 20-pack of juice bottles. The total c
posledela

Answer:

each bottle was $2.12 :P

Step-by-step explanation:

➼start by making an equation to find the price of the juice pack, in this case x would be the price of the juice pack because its unknown, the juice pack price(x) added to the price of the oranges(2.72) and equal the total(45.12), the before tax part is not needed info

2.72 + x = 45.12

➼now our aim to get x alone to find out its worth so we will have to do the opposite and subtract 2.72 from everything, since its positive

2.72-2.72=0 crosses out

45.12-2.72=42.4

➼which gets us x = 42.4 so one 20 pack is 42.40 dollars but we arent done yet, to find out the price of EACH bottle we must divide 42.4 by 20!

42.4/20=2.12

➼so to sum it up, each bottle is $2.12 :)

Y= − 2 ( x − 2 ) ( x + 8 ) −2(x−2)(x+8) in standard form
Harlamova29_29 [7]

Answer:

y=-4x^{2} -24x+64

Step-by-step explanation:

y=-2(x-2)(x+8)-2(x-2)(x+8)

y=-2x^{2} +12x+32-2(x-2)(x+8)

y=-2x^{2} -12x+32-2x^{2} -12x+32

y=-4x^{2} -24x+64

Find the coordinates of the center of the following circle.<br><br> (x - 3)² + (y - 7)² = 49
Zepler [3.9K]

When you write the equation of a circle in the form

(x-x_0)^2+(y-y_0)^2=r^2

Then the center of the circle has coordinates (x_0, y_0) and the radius is r

So, in your case, the center of the circle is (3,7)
