To figure out how much she travels in one hour you just do 567÷9 so...
567÷9=63
Helen travels 63 miles per hour
The answer is about 36.9%
I just guessed and checked. 95-60= 35
So .3685×95 is the closest to equaling 35
X will equal 12, and y will equal 18.
Y+9=1/5x menjadi y= 1/5x -9
sesudah ini sibtusika n dalam persamaan 4x - 5y = -15x
<span> 4x -5(1/5x-9)= -15 x
4x + x+45=-15x
5x +45 = -15x 45=-20x
x=-45/20
x= -9/4
y+9 =1/5x
y = 1/5(-9/4)-9
y = -189/20
(-</span>9/4,-189/20)
