There are 47 people attending a play at an outdoor theater. There are 11 groups of people sitting in groups of 3 or 5. How many
iVinArrow [24]

Answer:

  • <u>The number of groups in 3 is 4 groups.</u>
  • <u>The number of groups in 5 is 7 groups.</u>

Step-by-step explanation:

Let the number of groups in 3 ⇒ x

Let the number of groups in 5 ⇒ y

There are 11 groups. ⇒ x + y = 11         →(1)

There are 47 people. ⇒ 3x + 5y = 47  →(2)

Solve (1) and (2) to get x and y.

From (1)  ⇒ y = 11 - x  →(3)

By substitution from (3) at (2) with y

∴ 3x + 5(11-x) = 47

3x + 55 - 5x = 47

-2x = 47 - 55 = -8

∴ x = -8/-2 = 4

∴ y = 11 - x = 11 - 4 = 7

So, the number of groups in 3 is 4 groups.

the number of groups in 5 is 7 groups.

Find an equation of the circle that has center(-3,4) and passes through(1,-2)
Yuliya22 [10]

Answer:

  (x +3)^2 +(y -4)^2 = 52

Step-by-step explanation:

The standard form equation of a circle with center (h, k) and radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

We are given the value of (h, k), and we can find the value of r^2. Using the values of h and k, our equation is ...

  (x +3)^2 +(y -4)^2 = r^2

Since we know this equation is satisfied by the point (1, -2), we can use this point in the equation to find r^2:

  (1 +3)^2 +(-2 -4)^2 = r^2

  16 +36 = r^2 = 52

The equation of the circle is ...

  (x +3)^2 +(y -4)^2 = 52

£399 is shared between Ann, Bill, Chloe and Dave.
lukranit [14]

Answer:

Ann=£38

Bill=£171

Chloe=£95

Dave=£95

Step-by-step explanation:

By the information provided we can create an equation:

2x+9x+2*5x=399\\11x+10x=399\\21x=399\\x=19

Now that we know x, we multiply it correspondingly.

For Ann -> 2*19=38

Bill -> 9*19= 171

Chloe and Dave have the exact same amount each (because they both have 2.5 times the amount Ann's money)

Chloe/ Dave -> 5*19=95 each.
