We know that 1 foot is 12 inches then, we change all quantities to inches to ease the calculations:
5 ft 9 in = 5(12) + 9 = 60 + 9 = 69 inches
10 ft 11 in = 10(12) + 11 = 120 + 11 = 131 inches
so we add:
<span>5 ft 9 in + 10 ft 11 in
= 69 inches + 131 inches
= 200 inches
if we want the result in foot we divide:
= 200/12
= 100/6 = 50/3
= 16 ft 8 in</span>
Answer:
y = -2x + 27
Step-by-step explanation:
Firstly, we shall need to reform the given line equation;
y-7 = 1/2 ( x + 2)
y - 7 = x/2 + 1
y = x/2 + 1 + 8
y = x/2 + 8
Comparing this with y = mx + c
where m is the slope, then the slope of the line is 1/2
Since the line we are looking for has a slope perpendicular to this line, it means that the product of their slopes is -1
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
So we want an equation with slope -2 passing through (6,15)
we use the point slope method here;
y-y1 = m(x-x1)
y-15 = -2(x-6)
y-15 = -2x + 12
y= -2x + 12 + 15
y = -2x + 27
99.8 off because if you subtract it and it will be 99.8 off
