0.3x = 0.2 - 0.2x
0.5x = 0.2
x =0.2/0.5 = 2/5

D) The number that is 5 to the right of -6 on the number line
Hope this helps :)
Answer:
L = 11 m
Step-by-step explanation:
The perimeter is 40 m, which in turn equals 2L + 2W. With W = 9 m, we have:
40m = 2L + 2(9 m), or 40 m = 2L + 18 m, or 22 m = 2L. Then L = 11 m.
Answer:
option A
Step-by-step explanation:
the statement tell us that she slides the triangle 2 units down, so the vertical axis is the one that we are going to modify
we have the points: (1,2), (3,3) and (4,1)
so to these points we subtract "2" to the variable Y
I mean:
(1,2): 2-2=0
(3,3): 3-2=1
(4,1): 1-2=-1
finally we have:
(1,0), (3,1) and (4,-1)
Answer:
112
Step-by-step explanation:
use substitution method:
make 2 equations:
44 = 2(l+w) l=w+6
plug in l:
44 = 2 (w+6+w)
combine like terms:
44 = 2(2w+6)
distribute:
44 = 4w + 12
get 4w alone:
44 = 4w + 12
-12 -12
__________
32 = 4w
Divide to get w alone :
32 = 4w
__ __
4 4
w=8
plug w in:
l = w + 6
l = 8 + 6
get l alone on one side:
l = 14
plug l and w in an are equation:
14 x 8 = 112
