The answer is 75! Explanation, use the distance formula
4miles ..............56 minutes
42miles .............x
x= (42*56)/4
x= 2352/4
x= 588
So what you would do is 8/5 + 4 x 7 = 26.9
then you round it to 30
4x + 5y = 9
5y = -4x + 9
y = -4/5x + 9/5......slope intercept form (y = mx + b)
In y = mx + b form, which is what this equation is in now, the slope is in the m position and the y int is in the b position
y = mx + b
y = -4/5x + 9/5
so ur slope(m) = -4/5 and ur y int (b) = 9/5
i tried 2 different calculators and 3 different calculators the three online said the same answer whish is this 3.253064e+133 and my two calculators both said error try again literally but your answer is
<h2>
3.253064e+133</h2>
