Ingrid mixes 3.6 pounds of almonds with some raisins to make a trail mix. she divides the trail mix into 12 equal portions. each portion weighs 0.7 pound. how many pounds of raisins did she use to make the trail mix? express the answer to the nearest tenth.

Lets form an equation from this problem.
Let x=the mystery amount of raisins in the trail mix.
Our equation would be:
To solve for x we first multiply both sides by 12. This gives us    Next, we subtract 3.6 from both sides to get x=4.8
Ingrid used 4.8 pounds of raisins in the trail mix

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
