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 of a pound. How many pounds of raisins did she use to make the trail mix? Express the answer to the nearest tenth.
I NEED ANSWER
its 4.8 trust me just took the test.
Yep it is 408
I meant 4.8
To find out how many pounds of raisins Ingrid used to make the trail mix, we first need to determine the total weight of the trail mix.
We know that she mixes 3.6 pounds of almonds with some raisins. So the weight of the trail mix is 3.6 pounds + the weight of the raisins. Let's call the weight of the raisins "r".
The total weight of the trail mix (including almonds and raisins) is divided into 12 equal portions, with each portion weighing 0.7 pounds. Therefore, the weight of the trail mix is equal to 12 portions multiplied by 0.7 pounds per portion:
12 portions * 0.7 pounds/portion = 8.4 pounds
Now we can set up an equation to solve for the weight of the raisins (r):
3.6 pounds (almonds) + r (raisins) = 8.4 pounds (total trail mix weight)
To find the value of r, we need to isolate it on one side of the equation:
r = 8.4 pounds - 3.6 pounds
r = 4.8 pounds
Therefore, Ingrid used approximately 4.8 pounds of raisins to make the trail mix.
You do not just need ANSWER! You need to know how to solve problems like this in the future.
The 12 portions weigh a total of 12*0.7 = 8.4 lbs
So, the almonds weigh 8.4 - 3.6 = 4.8 lbs
X Lbs. of raisins.
(3.6+x)/12 = 0.7
3.6+x = 8.4
X =
