Answer:
Step-by-step explanation:
slope= y2-y1 / x2-x1
= -2-5 / 2-3
= -7 / -1
= 1
110/154 = x/126
154x/13860
x = 13860 /154 = 90

A line that is parallel to another has exactly the same slope as the other.
so a parallel line to that line above, will have the same slope hmmm what is the slope of <span>y=3/4x+2 anyway?
well, notice, since it's already in slope-intercept form </span>
Constants are 4,3. The coefficient is 4.
Answer:
Step-by-step explanation:
One of the cars are blue. it can travel 31 1/2 miles on 1 1/4 gallons of gasoline. Converting 31 1/2 miles to decimal, it becomes 31.5 miles. Converting 1 1/4 gallons of gasoline to decimal, it becomes 1.25 gallons of gasoline.
Therefore, the miles per gallon for the blue car is
31.5/1.25 = 25.2 miles per gallon.
Another car is red it can travel 28 4/5 miles on 4/5 gallon of gasoline.
Converting 28 4/5 miles to decimal, it becomes 28.8 miles. Converting 4/5 gallons of gasoline to decimal, it becomes 0.8 gallons of gasoline.
Therefore, the miles per gallon for the red car is
28.8/0.8 = 36 miles per gallon.
