Answer:
16 hours
Step-by-step explanation:
Multiply the 4/5 by 4 to get the denominator as 20. So you do 4 x 4 which equals 16 and 5 x 4 which equals 20 so you get 16/20 miles or 16 hours.
Bubbles 2, 3, 7 are the correct answers
Answer:
9526
Step-by-step explanation:
simplify 3^3+27
4+3*6(4-27)^2
simplify: 4-27+ -23
4+3*6(-23)^2
since the power of 2 is even it will be a positive
4+3*6*23^2
simplify: 23^2 to 529
4+3*6*529
simplify 3*6 to 18
4+18*529
then simplify 18*529 to 4+9522
and 4+9522= 9526
