At a hardware store a bag holds up to 1 pound of nails. Each penny nail (x) weighs 0.05 pounds and each wood nail (y) weighs 0.1 pounds. Which inequality shows the solution for all combinations of the two kinds of nails that will fit in the 1-pound bag?
2 answers:
For this answer, you multiply the weight of each penny nail by x and the weight of each wood nail by y. If the bag holds one pound of nails, you would use the inequality ≤. .05x + 0.1y ≤ 1
Answer:
Step-by-step explanation:
Let the penny nails be represented by x
Let the wood nails be represented by = y
Each penny nails weigh = 0.05 pounds
Each wood nail weigh = 0.10 pounds
Now we have been asked about the inequality which shows the solution for all combinations of the two kinds of nails that will fit in the 1-pound bag.
So, the inequality becomes:

Question:
What is the equation for the following statement,"One-half of a number decreased by 3 is 21.
Answer:
<em>half the number = x/2 </em>
<em>decreased by 3 </em>
<em>(x/2) -3 =21</em>
<em>=48</em>
Answer:
8/21
Step-by-step explanation:
1- 2/7 - 1/3 = 21/21 - 6/21 - 7/21 = 8/21
