2/3x=7/84
16=1
9=4
The solución is by dividing
this is the quadratic formula
1.80x + 3 = 12
isolate the x
1.80x + 3 (-3) = 12 (-3)
1.80x = 9
1.80x/1.80 = 9/1.80
x = 9/1.80
x = 5
you can travel up to 5 miles
hope this helps
The surface area of the square bottom = L x W = 7 x 7 = 49 cm^2
The area for one of the triangles = 1/2 x base x height = 1/2 x 7 x 9 = 31.5 cm^2
There are 4 triangles, the total area for the triangles = 31.5 x 4 = 126 cm^2
Total area = base + triangles = 49 + 126 = 175 cm^2
Asumming that 3/5 is the number of miles Jennifer has gone in 1/5 of an hour. We can take 60 (# of minutes in an hour) divided by 5, which equals 12. So 3/5 is 36 minutes. to figure out how many 1/5 are in 8 miles we would take 8 times 5 which is 40. We would then take 3 times 8, which is 24. 40 - 24 = 16. So 16 times 5 = 80 minutes. 80 divided by 60 (# of minutes in an hour) is 1 hour and 20 minutes. So it takes Jennifer 1 hour and 20 minutes to travel 8 miles.
