Answer:

x = 5 pens

y = 7 pencils

Step-by-step explanation:

let

x = the number of pens

y = the number of pencils

Anthony spent $2.80 to buy a total of 12 pens and pencils

0.35x + 0.15y = 2.80

x + y = 12

by solving the system of equations

0.35x + 0.15y = 2.80

x + y = 12

we find

x = 5 pens

y = 7 pencils

Simplify the polynomial expressions by combining like terms, and then multiply the resulting
dimaraw [331]

Answer:

The simplified expression is

20x^2 - 33x - 27

Step-by-step explanation:

(6x - 9 - 2x)(8 + 5x - 5)​

We must first rewrite the expression as a product of two binomials.

This can be done by adding like terms

(6x - 9 - 2x)(8 + 5x - 5)​

We have,

(4x-9)(5x+3)

Multiplying the resulting binomial expression

(4x-9)(5x+3)

(20x^2+12x-45x-27)

Add the like terms

20x^2-33x-27

The simplified expression is

20x^2 - 33x - 27

Twenty x squared minus thirty-three x minus twenty-seven

Lines are drawn on the gym floor for different sports for basketball playing area is marked so that there is an out of bounds. 2
choli [55]

Answer:

16 m  × 11 m

Step-by-step explanation:

The dimension of the gym is 20 m x 15 m. An outbound of 2m width is to be cut out from the gym to form the basketball court.

The original length of gym = 20 m and original width of gym = 15 m

2 m would be cut at both sides of the gym length for the outbound. Also 2 m would be cut at both sides of the gym width for the outbound. Therefore:

Length of basketball court = 20 m - (2 * 2m) = 20 m - 4 m = 16 m

Width of basketball court = 15 m - (2 * 2m) = 15 m - 4 m = 11 m

Therefore the dimensions of the basketball court is:

16 m × 11 m
