1 gram = .001 kg
5.1kg = 5100g
let the number = x
x*80/100 = 55
x = 5500/80
x=68.75
After rounding off, it will remain 68.75
Answer:
She changed the symbols in the first two problems because they were divided by a negative number whereas she shouldn't have changed the symbol in the last problem as it was not divided by a negative number and so the sign remains the same.
X-intercept = (x,0) y is zero
y- intercept = (0,y) x is zero
In the equation y = -1/2 x -5
x-intercept would be
0 = -1/2 x - 5
5 = -1/2x
x = -10
y-intercept would be
y = -1/2 (0) - 5
y = -5
Thus, the answer is (-10,0) and (0,-5).
