Answer: 3-subject notebook cost $0.67 or 67 cents and the single-notebook cost $0.33 or 33 cents.
Step-by-step explanation:
Let's represent the 3-subject notebook by y and the single-notebook by x.
y has to cost twice as much as x and we can represent that by the equation
y = 2x
We now know that the total cost of the 3-subject notebook and the single-subject notebook has to equal $1.
We can also represent that by the equation and solve for x
2x + x = 1
3x = 1
x = 0.33 $0.33 or 33 cents
If the single-subject is $33 cents then subtract it from a dollar to see how much the 3-subject notebook costed.
1- 0.33 = 0.67

Answer:
13 inches and 10 inches
Step-by-step explanation:
First, let's find the factor pairs that make up the area of 130 square inches.
Next, let's see the factor pairs that make a perimeter of 46 inches by using the formula 2(l + w).
- 2(1 + 130) = 2(131) = 262
- 2(2 + 65) = 2(67) = 134
- 2(5 + 26) = 2(31) = 62
- 2(10 + 13) = 2(23) = 46
Therefore, the dimensions of the folder are 13 inches and 10 inches.
