Answer:
-38.2
Step-by-step explanation:
Answer:
19 red beads
Step-by-step explanation:
We first need to find a common denominator of 4/9, 1/5 and 1/4.
The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.
Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.
Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.
Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.
180 - (silver+gold+blue) = red beads
180-161 = 19 red beads b/c ----->
80+36+45+19 = 180
Answer:
7
Step-by-step explanation:
12-(-3)-2(4)
12-(-3)-8
15-8=7
slope of line y= -2x is -2
slope of line L= (-1)reciprocal of slope line y= -2x.
=( -1)(-1/2)
=1/2
since the L passes through (2,-4),
equation of line L: y-(-4)= 1/2(x-2)
2y+8 = x-2
x-2y-10=0
Hence equation of line L is x-2y-10=0
