Evaluate abc if a = -2/5 , b = 20/32, and c = -4/10 . Express your answer as a fraction in simplest form. *
A.4/40
B.-1/10
C.160/1600
D.1/10

Remember that when multiplying fractions, we multiply everything on the top and everything on the bottom.

a * b * c

(-2 / 5) * (20 / 32) * (-4 / 10)

(-2 * 20 * -4) / (5 * 32 * 10)

160 / 1600

1 / 10

Correct D. 1/10

Hope this helps!! :)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
