Gnom [1K]

102 adult tickets were sold.

Step-by-step explanation:

Let,

Adult tickets = x

Children tickets = y

According to given statement;

x+y=146 Eqn 1

8x+5y=1036 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 5\\5(x+y=146)\\5x+5y=730\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(8x+5y)-(5x-5y)=1036-730\\8x+5y-5x-5y=306\\3x=306\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{306}{3}\\x=102\\$

4w2 + 3W

timama [110]

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

$Area = 20w^3 + 7w^2 - 11w + 2$

Step-by-step explanation:

Given

$Length = 4w^2 + 3w - 1$

$Width = 5w - 2.$

Required

Determine an expression for the area

Area is calculated as:

$Area = Length *Width$

$Area = (4w^2 + 3w - 1) * (5w - 2)$

Expand

$Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2$

Collect like terms

$Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2$

$Area = 20w^3 + 7w^2 - 11w + 2$
