Find the value of x in the following parallelogram

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
