What is difference between -0.4 and 44.4 a) 40 b) 44 c) -44 d)44.8

d

Step-by-step explanation:

44,4 - (-0,4) = 44,4 + 0,4= 44,8

Step-by-step explanation:

44.4--0.4=-44

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.
