Answer:
A
Step-by-step explanation:
49y² - x² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
49y² - x²
= (7y)² - x²
= (7y - x )(7y + x) → A
Answer:
A. 10
Step-by-step explanation:
I found a website that explains that you need 8.3 grams of coffee to make one 5-fl oz cup of coffee.
To make 600 cups, you need 600 * 8.3 g = 4980 g
Now we convert 4980 g to lb.
1 lb = 454 g
4980 g * (1 lb)/(454 g) = 11 lb
The closest answer is A. 10
Answer: A. 10
Answer:
b = -4/3
Step-by-step explanation:
First, subtract the 1/2 over
-1/4b+1/2=5/6
5/6-1/2
To get a common denominator of 6, multipy 1/2 by 3
5/6-1/2(3)
5/6-3/6=2/6
-1/4b=2/6
Next, multiply by the reciprocal of -1/4, or -4
(-4)-1/4b=2/6(-4)
b=-4/3
