Divide.
1/3 / 5
Or multiply by the reciprocal of 5:
1/3 * 1/5 = 1/15
Therefore 1/15 cup of flour is used to make 1 dinner roll.
We can set up a proportion:
5/1/3 = x/5 2/3
Multiply 5 2/3 to both sides:
28 1/3 / 1/3 = x
85 = x
So 85 rolls can be made with 5 2/3 cups of flour.
Answer:
x - 17
Step-by-step explanation:
x is how much Juan spent. Linda spent 17 less. x - 17 = How much Linda spent
Answer:
-1
Step-by-step explanation:
See the attachment for the polynomial long division. The constant in the quotient is -1.
_____
Here, there is a remainder of -x. If there were no remainder the constant in the quotient is the ratio of the constant in the dividend to the constant in the divisor: -2/2 = -1.
That could be a first guess in a "guess and check" solution approach.
<em>Guess</em>: first term of binomial quotient is (2x^3)/x^2 = 2x; last term of binomial quotient is -2/2 = -1. So, the quotient is guessed to be (2x -1).
<em>Check</em>: (2x -1)(x^2 -x +2) = 2x^3 -3x^2 +5x -2
Subtracting this from the actual dividend gives a remainder of -x. This has a lower degree than the divisor, so no further adjustment of the quotient is required.
Answer: b=-12
Step-by-step explanation:
120/-10 = -12
-10b/-10 = b
b=-12
