A sporting goods store sells right-handed and left-handed baseballs gloves. In one month, 12 gloves were sold for a total of $56

Vesna [10]

3 left-handed and 9 right-handed gloves were sold.

Step-by-step explanation:

Let,

Left handed gloves = x

Right handed gloves = y

Cost of right-handed gloves = $45

Cost of left-handed gloves= $52

According to given statement;

x+y=12 Eqn 1

52x+45y=561 Eqn 2

$From\ Eqn\ 1\\x=12-y\\Putting\ this\ value\ of\ x\ in\ Eqn\ 2\\52(12-y)+45y=561\\624-52y+45y=561\\-7y=561-624\\-7y=-63\\Dividing\ both\ sides\ by\ -7\\\frac{-7y}{-7}=\frac{-63}{-7}\\y=9\\Putting\ y=9\ in\ Eqn\ 1\\x+9=12\\Subtracting\ 9\ from\ both\ sidesx+9-9=12-9\\x=3$

3 left-handed and 9 right-handed gloves were sold.

Which is the solution to the equation 2.6a + 18.4 = 28.8 round the nearest tenth if necessary. 1.4, 4, 18.2, 27

You would subtract 18.4 from 28.8 then divide that answer by 2.6. The answer would therefor be 4.

Solve by completing the square x^2=11x-2

son4ous [18]

Answer: x = ± 11+√113 ;

______

Step-by-step explanation:

x^2=11-2

Add two to both sides

x^2+2=11x-2+2

Simplify

x^2+2=11x

Subtract 11x from both sides

x^2+2-11x=11x-11x

Simplify

x^2-11x+2=0

Hope this helps!
