Answer:
She sold 39 tall candies and 52 short candies
Step-by-step explanation:
x is all the tall candies
y is all the short candies
x+y=91
8x+5y=572
Use the method of Substitution to find out both x and y.
x=91-y
8(91-y)+5y=572
728-8y+5y=572
728-3y=572
3y=156
y=52
x+52=91
x=39
Step-by-step explanation:
Given points ( 2 , 7) and ( - 8 , 1 )
Distance between two points
![\sqrt{(x2 - x1 )+( y2 - y1)}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28x2%20-%20x1%20%29%2B%28%20y2%20-%20y1%29%7D%20)
![\sqrt{(2 + 8) + (7 - 1)}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%282%20%20%2B%208%29%20%2B%20%287%20-%201%29%7D%20)
![\sqrt{10 + 6}](https://tex.z-dn.net/?f=%20%5Csqrt%7B10%20%2B%206%7D%20)
![\sqrt{16}](https://tex.z-dn.net/?f=%20%5Csqrt%7B16%7D%20)
![\sqrt {4}^{2}](https://tex.z-dn.net/?f=%20%5Csqrt%20%7B4%7D%5E%7B2%7D%20%20)
Therefore distance between two points is 4 units.
