Answer:
-2x + 5
Step-by-step explanation:
When you set this problem up:

It's easy to see that you can't really divide them due to their differing variables. So, we need to factor the numerator to give us equivalent variables:

WAIT! Look at the longer factor:

It is equivalent to our denominator! Now, that has made the job incredibly easier. Simply cancel out the like terms in the problem and we have our answer:
(-2x + 5)
12y = x + 23
Step-by-step explanation:
- y = −12x + 5
- Perpendicular slopes are opposite reciprocals.
- The original slope is −12
- So the new perpendicular slope is 1/12.
- We plug the point (1, 2) and the slope m = 1/12 into the slope intercept form of the equation y = mx + b
y = mx + b
2 = 1/12 * 1 + b
2 = 1/12 + b
b = 23/12
- When we simplify this, we arrive at 12y = x + 23
Gretchen walked more than a whole mile on both days combined, because if on Saturday she walked 7/10 miles, she would have only needed 3/10 of a mile more to walk on Sunday to make 1 mile. On Sunday, however, she walked 3/4 miles, and using common knowledge, we know that 3/4 miles is more than 3/10. Thus, Gretchen walked more than a mile on both days combined.
Answer:
B. 66
Step-by-step explanation:
73+25 = 98
Z = 98-32
Z = 66
