Answer:
5 cups of flour.
Step-by-step explanation:
I know the wording of the problem may be confusing at first, but if you look at it a little bit, it's just multiplication and division.
To start,
12 biscuits require 2 cups of flour,
meaning that 6 biscuits (half of the original) only require 1 cup.
<u>(12/2 = 6)</u>
Next,
We need to find how much flour is in 30 biscuits.
We know that 1 cup is in 6 biscuits, and if you were to find how much was in 30 biscuits, you would just need to divide 30 by 6.
<u>(30/6 = 5)</u>
5 cups of flour would be your answer.
To put it mathematically,
(12/2 = 6), (30/6 = 5)
Answer:
y=4/3x-7
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
5(x-5)=3(x-7)
Distribute
5x-25 = 3x-21
subtract 3x from each side
5x-25-3x = 3x-21-3x
2x-25 = -21
Add 25 to each side
2x-25+25 = -21 +25
2x=4
Divide by 2
2x/2 =4/2
x=2
I think it is B because it has a continuous line soy it couldn’t be a. It has negative numbers so it couldn’t be D. And it has negative numbers so couldn’t be C
The general form of a quadratic equation is that which is expressed in a form,
ax² + bx + c = 0
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
