Answer:
588 in³
Step-by-step explanation:
Break it up in three parts.
Left part: 7*8*3 = 168
Mid part: 6*6*7 = 252
Right part: 7*8*3 = 168
Sum: 168+252+168 = 588
4x - 24 = -2x + 30
4x + 2x = 30 + 24
6x = 54
x = 9
answer: the number is 9
Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable
Multiples of 5 : 65,70,75,80,85,90,95,100,105
multiples of 6 : 66,72,78,84,90,96,102
multiples of 10 : 70,80,90,100
she could choose : 90...and thats it
