Simplify the expression in part D to find the temperature of the water after Raul added the ice cubes. Show your work 70 + (-30)+2+(-9)+0.3+(-0.1)=[70+(-30)]+[2(-9)]+[0.3+(-0.1)]

33.2°F

Step-by-step explanation:

[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]

=

40 + (-7) + 0.2

=

33 + 0.2

=

33.2°F

The temperature of the water dropped to 33.2°F after Raul added the ice cubes.

Hoped this helped!<3

(30*2)/49

Step-by-step explanation:

let her morning walk distance be x

her evening distance walk =2 1/2 x

= 5x/2

her daily walk distance =5x/2+x

= 5x/2+2x/2=7x/2

her weekly walk distace= 7x/2*7=49x/2=30miles

x= (30*2)/49
