Answer:

Step-by-step explanation:
To evaluate :

Solution:
Two negatives multiply to become a positive.
Thus, we can remove parenthesis by reversing the signs of the fraction by multiplying the negative outside.
⇒ 
Since the denominators are same for both fractions, so we simply add the numerators.
⇒ 
⇒
(Answer)
Answer: Undefined
The x coordinates are the same, so a vertical line forms. All vertical lines have undefined slopes.
We can see it through the slope formula
m = (y2-y1)/(x2-x1)
m = (3-(-6))/(2-2)
m = (3+6)/(2-2)
m = 9/0
We cannot divide by zero, so the result is undefined.
Answer:
A. 32 g
B. 3670 g
Step-by-step explanation:
Basket + 25 bars: 1110 g
Basket: 310 g
25 bars: 1110 g - 310 g = 800 g
1 bar: 800 g / 25 = 32 g
105 bars: 105 × 32 g = 3360 g
Basket + 105 bars: 310 g + 3360 g = 3670 g
Answer:
A. 32 g
B. 3670 g
The unit rate is 9 miles per hour.
In order to find how much its unit rate will be you need to use this expression below.
<em>n = number of hours</em>
<em>m = number of miles </em>
m divided by n or <em>m/n</em>
In order to find how much does he travel in given hours see this below.
<em>n = number of hours</em>
<em>m = number of miles for 1 hour</em>
<em>nm or n * m</em>
