Answer:

50 de copii

Step-by-step explanation:

În această întrebare, fiecare dintre copii primește o carte pentru 32 de lei și o ciocolată pentru 8 lei.

Ceea ce înseamnă că suma totală primită de fiecare dintre copii va fi de 32 + 8 = 40 lei

Acum, din moment ce suma totală cheltuită este de 2000 de lei, numărul copiilor care se dau cărți și ciocolată va fi de

2000/40 = 50 de copii

If a person who works 40 hours per week earns $52,000 per year, estimate that person’s hourly wage. Use the estimate that there
oksano4ka [1.4K]
The hourly wage is approximately $26 per hour. Find out how many hours the person works per year by multiplying 40 x 50 to get 2,000 hours. Then divide 52,000 by 2,000 to get the person's hourly wage, which is $26 hours per hour.

Please help me out with this!!<br> BRAINLIEST AVAILABLE!!
lapo4ka [179]

Answer:

xy = 1

k = 79

Step-by-step explanation:

Question One

The first and third frames look to me to be the same. I'll treat them that way.

y = x^2                        Equate y = x^2 to the result of 2y + 6 = 2x + 6

2y + 6 = 2(x + 3)         Remove the brackets

2y + 6 = 2x + 6           Subtract 6 from both sides

2y = 2x                       Divide by 2

y = x

Now solve these two equations.

so x^2 = x                  

x > 0

1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is

x(x) = x                           Divide both sides by x            

x = 1                            

y = x^2                           Put x = 1 into x^2

y = 1^2                           Solve

y = 1                      

The second solution is

(1,1)

xy = 1*1

xy = 1

Answer: A

Question Two

square root(k + 2) - x = 0

Subtract x from both sides

sqrt(k + 2) = x                Square both sides

k + 2 = x^2                    Let x = 9

k + 2 = 9^2                    Square 9

k + 2 = 81

k = 81 - 2

k = 79
