0.76 x 2 = 1.52
1.40 x 2 = 2.80
1.52 + 2.80= 4.32
Answer is 4 dollars and 32 cents
After you find the first quotient term, 3x, the dividend for the next stage of long division is
9x² - 4 - 3x(3x+1) = -3x -4
Then the next quotient term is (-3x)/(3x) = -1.
The missing value is -1.
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
