Answer:

The values of x and y that satisfy the equation are 2 and 2, respectively.

Step-by-step explanation:

Two complex numbers are identical if and only each pair of respective coefficients are identical on both sides. Then, we need to observe the following conditions:

Real component

4\cdot x = 8 (1)

Imaginary component

2 = y (2)

The solution of this system of equations is x = 2 and y = 2.

The values of x and y that satisfy the equation are 2 and 2, respectively.

On a certain hot summer day, 481 people used the public swimming pool. The daily prices are 1.25 for children and 2.25 for adult
spayn [35]

Answer:the number of children that swam in the public pool that day is 222

the number of adult that swam in the public pool that day is 259

Step-by-step explanation:

Let x represent the number of children that swam in the public pool that day.

Let y represent the number of adult that swam in the public pool that day.

On a certain hot summer day, 481 people used the public swimming pool. This means that

x + y = 481

The daily prices are 1.25 for children and 2.25 for adults. The receipts for admission totaled to 86.25. This means that

1.25x + 2.25y = 860.25 - - - - - - - -1

Substituting x = 481 - y into equation 1, it becomes

1.25(481 - y) + 2.25y = 860.25

601.25 - 1.25y + 2.25y = 860.25

- 1.25y + 2.25y = 860.25 - 601.25

y = 259

Substituting y = 259 into x = 481 - y, it becomes

x = 481 - 259

x = 222

3. Given the image below, find the measure of ZYVZ, in degrees.<br> (3x + 5)º<br> N
pashok25 [27]

Answer:

∠ YVZ = 56°

Step-by-step explanation:

∠ WVZ = 90° ( given ), thus

∠ WVY + ∠ YVZ = 90, substitute values

2x + 3x + 5 = 90

5x + 5 = 90 ( subtract 5 from both sides )

5x = 85 ( divide both sides by 5 )

x = 17

Thus

∠ YVZ = 3x + 5 = 3(17) + 5 = 51 + 5 = 56°
