Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
Hi there! :)
A radical equation is an equation in which a variable (ex. x, y, a, v) is under a radical sign. The only equation that has a variable under a radical (x) is the second option. There is an x next to the 2 under the radical.
I hope this helps, DM me if you have anymore questions. :)

Answer:
A. 288.62
Step-by-step explanation:
Area of two triangles = 15.3 * 10.4 = 159.12
Area rectangle = hypotenuse triangle * 7
hypotenuse = √108.16 + 234.09
Hypotenuse = 18.5
Area rectangle = 18.5 * 7 = 129.5
129.5 + 159.12 = 288.62
Answer = A. 288.62

we are given
x-intercept is 3
so,
a=3
y-intercept is 2
b=2
now, we can intercept formula of line
now, we can plug
a=3 and b=2
now, we will get rid of denominators
so, we can multiply both sides by 6
we can also write it as
so, option-D..................Answer
