weqwewe [10]

133 adult tickets were sold.

Step-by-step explanation:

Given,

Total tickets sold for school play = 399

Let,

x represent the number of children tickets sold.

y represent the number of adult tickets sold.

According to given statement;

x+y=399      Eqn 1

x = 2y           Eqn 2

Putting value of x from Eqn 2 in Eqn 1

2y+y=399\\3y=399

Dividing both sides by 3

\frac{3y}{3}=\frac{399}{3}\\y=133

133 adult tickets were sold.

How do I solve this? Please show work, thank you.
irina [24]

Answer:

a   x sqrt(7) - 49sqrt(x)

Step-by-step explanation:

sqrt(7x) [ sqrt(x) - 7sqrt(7)]

Distribute

sqrt(7x) *sqrt(x) - sqrt(7x)*7sqrt(7)

We know that sqrt(a) sqrt(b)= sqrt(ab)

sqrt(7x^2)  - 7sqrt(7^2 *x)

Now lets separate out the perfect squares

sqrt(7) *sqrt(x^2) - 7sqrt(7^2)*sqrt(x)

x sqrt(7) - 7*7sqrt(x)

x sqrt(7) - 49sqrt(x)

8 of the 12 students on a soccer team are on the honor roll. if the relationship on this team is proportional to the number of h
Mrrafil [7]

Answer:

267 students

Step-by-step explanation:

Number of students in a team (t) is proportional to number of honor roll students (n)

Mathematically, t = kn (k is constant

When t = 12, n = 8

k = t/n = 12/8 = 1.5

When t = 400

n = t/k = 400/1.5 = 267 (to the nearest whole number)
