Step-by-step explanation:

Each could be watched in the places of 1,2,3 or 4. So each movie has 4 places it could be. Since you rented 4 movies you would do 4x4 which equals 16.

Meaghan goes to the grocery store to buy hot dogs and hamburgers for a cookout. She buys a total of 12

Archy [21]

The system of equations is d+b=12 and 2.59d+5.49b=36.88 and Meaghan bought 10 packages of hot dogs and 2 packages of hamburgers.

Step-by-step explanation:

Cost of one package of hot dog = $2.59

Cost of one package of hamburgers = $5.49

Packages bought = 12

Cost of packages = $36.88

Let,

Packages of hot dogs = d

Packages of hamburger = b

According to given statement;

d+b=12 Eqn 1

2.59d+5.49b=36.88 Eqn 2

Multiplying Eqn 1 by 2.59

$2.59(d+b=12)\\2.59d+2.59b=31.08\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(2.59d+5.49b)-(2.59d+2.59b)=36.88-31.08\\2.59d+5.49b-2.59d-2.59b=5.80\\2.90b=5.80$

Dividing both sides by 2.90

$\frac{2.90b}{2.90}=\frac{5.80}{2.90}\\b=2$

Putting b=2 in Eqn 1

$d+2=12\\d=12-2\\d=10$

The system of equations is d+b=12 and 2.59d+5.49b=36.88 and Meaghan bought 10 packages of hot dogs and 2 packages of hamburgers.

After t years, the remaining mass y (in grams) of an initial mass of 35 grams of a radioactive element whose half- life is 80 ye

IgorC [24]

Answer: There will be 22.694 grams of initial mass remains after 50 years.

Step-by-step explanation:

Since we have given that

$y=35(\dfrac{1}{2})^{\frac{t}{80}$

We need to find the quantity of initial mass remains after 50 years.

So, t = 50 years,

We get that

$y=35(\dfrac{1}{2})^{\frac{50}{80}}\\\\y=35(0.5)^{0.625}\\\\y=22.694$

Hence, there will be 22.694 grams of initial mass remains after 50 years.

5x + 3(x-5) = 6x + 2x -15 solve the equation and write the number of solutions. Name one property you used to solve this equatio

Ratling [72]

Answer:

infinite number

Step-by-step explanation:

Carry out the multiplication indicated here:

5x + 3(x-5) = 6x + 2x -15 => 5x + 3x - 15 = 6x + 2x -15

Now combine the x terms: We get 8x - 15 = 8x - 15, or -15 = -15.

This last result is always true, so this equation has an infinite number of solutions.
