180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
That is a strangely worded question... but I think you're asking how many people said they got a 6 but did not.
So, a dice that has 6 sides has a 1/6 chance of Landing on a 6. so 1/6 of 360 should be that 60 people got a 6. Therefore 119-60 = 59.
The proportion is 59/360 that lied
So you know if a and b are the numbers that a+b=36 and a-b=4 so you can solve one I solved the second equation for a a=4+b and plugging that a value into equations gives you 4+b+b=36
This simplified to 4+2b=36
2b=32
B=16 so you know one number is 16 and you can plug it in to find a a-16=4 so a=20
Therefore the two numbers are 16 and 20
Answer:
-6×12×-1=72
Step-by-step explanation:
just note that abs(k)
when k<0
is -k
y-6x - 6=0
y = 6x + 6; slope = 6 and y intercept b = 6
Perpendicular lines, slope is opposite and reciprocal
so other line has slope = - 1/6, they both intersect in y a-xis so they intersect at (0,6) so other line also has b = 6
Equation of other line
y = -1/6 x + 6
