Answer:
9.6
Step-by-step explanation:
you would do 3.2+3.2, which equals 6.4. Then you would do 1.6+1.6 which is 3.2. Add 6.4 and 3.2 and you get 9.6
10/5 is 2, and that is in simplest form.
Answer:
53 + 3g ≤ 65, g ≤ 4
Step-by-step explanation:
To solve for g:
53 + 3g ≤ 65
First, subtract 53 from both sides.
53 - 53 + 3g ≤ 65 - 53
=> 3g ≤ 12
Divide 3 by both sides
=> 3g / 3 ≤ 12 /3
=> g ≤ 4
Therefore, g ≤ 4
Hope this helps :)
