8. Mehrab works in a department store selling
sports equipment. Baseball gloves cost $29
each and bats cost $14 each. One shift, he
sells 28 items. His receipts total $647.
a) How many bats did Mehrab sell?
b) How many gloves did he sell?

Mehrab sold  11 bats and 17 gloves.

Step-by-step explanation:

Let x represent the number of gloves and y represents the number of bats.

Then on one shift Mehrab has sold 28 items

so , x+y = 28 .....................................(1)

The cost of all 28 items  is $647

that is, cost of x gloves + cost of y bats  = 647

x(29) + y (14) =  647...................................(2)

Multiply eq(1) by 14 , we get

14x +14y = 392.....................................(3)

Subracting (3) from (2)

29x +  14y =  647

14x +    14y =  392

------------------------------

15x + 0y =  255

--------------------------

15x =  255

x  =

x =  17

Substituting the x value in  eq(1), we get

17 + y = 28

y =  28 -17

y = 11

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.

it would rotate about 180 degrees.
