<u> Answer:</u>

<u>(-∞,8)</u>

<u>Step-by-step explanation:</u>

<u />

<u>So the interval for the solution of a certain set is the numbers that can be used as value for X in the set and the set still be true, in order to solve this, you just need to solve the set by making it an equation:</u>

<u />

<u>0.35x – 4.8 < 5.2 – 0.9x</u>

<u />

<u>0.35x – 4.8 =5.2 – 0.9x</u>

<u />

<u>0.35x+0.9x=5.2+4.8</u>

<u />

<u>1.25x=10</u>

<u />

<u>x=8</u>

<u />

<u>So the maximum value of X will be 8, and when X is a negative value the set is true, so the interval would be all real numbers form -infinite to 8.</u>

<u />

<u>(-∞,8)</u>

What expression represents the area???
galben [10]

Answer:

B.

Step-by-step explanation:

Area is width times height.

(5p-7)(3p+4)

Multiply using FOIL method

(First, outer, inner, last)

(5p*3p) + (5p*4) + (-7*3p) + (-7*4) =

15p² + 20p -21p - 28 =

15p²-p -28 =

B is the closest one. They might have made a typo.

Answer:

35 in²

Step-by-step explanation:

The irregular shaped can be divided into two squares and one rectangle, so the area will be the additions of the area of the squares and the rectangle

area of square A = L *B = 3 *3 = 9in²

area of square B = L * B = 4*4 = 16in²

area of rectangle C = L * B = 5 *2 = 10in²

th area of the irregular shape = 9 in² + 16 in² + 10 in² = 35 in²

A bowling alley charges $2.50 per game plus $4 to rent shoes. A second bowling alley charges $4 per game plus $1 to rent shoes.
adelina 88 [10]

Answer:

The person would have to play 2 games for the two bowling alleys to cost the same amount

Step-by-step explanation:

Assume that the number of games that makes the two costs equal is x

∵ A bowling alley charges $2.50 per game plus $4 to rent shoes

∵ The number of games is x

∴ The cost = 2.50x + 4

∵ A second bowling alley charges $4 per game plus $1 to rent shoes

∵ The number of games is x

∴ The cost = 4x + 1

∵ They have the same cost

→ Equate the 2 expressions above

∴ 4x + 1 = 2.50x + 4

→ Subtract 2.50x from both sides

∵ 4x - 2.50x + 1 = 2.50x - 2.50x + 4

∴ 1.50x + 1 = 4

→ Subtract 1 from both sides

∵ 1.50x + 1 - 1 = 4 - 1

∴ 1.50x = 3

→ Divide both sides by 1.50

∴ x = 2

∴ The person would have to play 2 games for the two bowling alleys to

   cost the same amount
