Choose the expression that would equal the number of hours in the following question.

1 answer:

5 0

<span>B. 285/302. This is the correct answer because it is the only choice which is roughly the same ratio as 47.5/50.5 which is the ratio needed to determine how long it would take to go 47 1/2 miles in a car that averages 50 1/2 miles per hour. The mathematical equation which represents the problem is: 50.5/1 = 47.5/A (A = hours) which is the same as 50.5 A = 47.5 which means A = 47.5/50.5 which means A = .94 hours. 285/302 also equals .94.</span>

How many solutions does the following have?<br><br>Y = x - 1<br>& <br><br>y - x = -9

n200080 [17]

Answer:

No solution

Step-by-step explanation:

y=x-1 and y-x=-9

1st make sure both equations are in slope intercept form

since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so

y-x=-9

+× +×

y=×-9

now you have y=x-1 and y=x-9

substitute the y with the other equation

x-1=x-9

subtract x from both sides since you can't have the variable on both sides

now you've got -1 = -9

and since that equation isn't true, it has no solution.
