Question

Help me with 2 and 3 and 4 but can you explain how to use substitution to check number 1? Thx peeps pls help will give brainliest promise :)

Answer 1

Answer: (Q1). First, isolate the varaible. Add 17 to both sides of the equation. Then, you have b = 44. (Q2). You can rewrite 4(6) into (4)6. (Q3). The volume of the rectangular prism is 136 4/5. (Q4). 2/9 x 5/8 is 5/36.

Step-by-step explanation:

Answer 2

For number 3 you need to do L+W+H ( length, width, and height ) ! First you need to take the mixed fraction and solve it so it will leave you with a whole number which will make it way easier.
For number 4
2/5 x 9/8 = cross multiply !! 10/72 is the answer but you have to find common factors of 10 and 72 to get the correct answer ! After you get 10/72 then divide both numbers by 2 and that gives you the fraction in simplest form and then your done !!
