Translate to a system of equations but do not solve. one evening 1600 concert tickets were sold for the Fairmont summer jazz festival. tickets cost $20 for covered pavilion seats and $15 for lawn seats. total receipts for $27,000. how many of each type of tickets were sold?

let x equal the number of pavilion seats sold.
let y equal the number of lawn seats sold

complete system of equations.

x+y=
| |x + | |y = 27,000

which expression represents the approximate length of bc?

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

the answer is:

mean: 6

mad: 2.14

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
