Answer & Step-by-step explanation:
37.
Linda walked 3/4 (or 75%) of a track which is 3.5 miles long
Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)
38.
We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)
1/8 is 0.125
2/8 is 0.25
3/8 is 0.375
The track is 2.375 miles long.
Multiply 2.375 by 2.5
The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)
Step-by-step explanation:
Multiply everything in the parenthesis.
24. (2xy)( -4x²) + (6x)(6x²y)
---> -8x³y + 36x³y
= 28x³y
25. (2ab²)(4a²b³) - (10a³b)(6b⁴)
---> 8a³b^5 - 60a³b^5
= -52a³b^5
Sorry, i cant turn the 5 into an exponent on my phone lol. but i hope this helps.
