A field goal kicker makes 84% of the field goals he attempts he has attempted 50 field goals this season how many goals hs he made

He has made 42 field goals this season

Step-by-step explanation:

To find x% of number y, multiply y by ⇒ × y

∵  A field goal kicker makes 84% of the field goals he attempts

→ That means he makes 84% of his total attempts

∵ He has attempted 50 field goals this season

→ That means his total attempts is 50 field goals

∴ He makes 84% of 50 field goals

∵ 84% = 84 ÷ 100 = 0.84

∴ He makes 0.84 of 50

∵ He makes = 0.84 × 50

∴ He makes = 42 field goals

∴ He has made 42 field goals this season

answer: the value of x is 7cm

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
