R - 18 = 50
r = 50 + 18 = 68
Hence Rick is 68 yrs old
It is 1,01000 is the answer
5.
6 / t = 9 / (t+2)
9t = 6t + 12
3t = 12
t = 4 answer
The remaining length:-
6 / 4 = 11 / x
6x = 44 so x = 7.33 answer
6. 8 / w = 6 / (w - 5)
6w = 8w - 40
2w = 40 so w = 20 answer
The side marked w - 5 = 20-5 = 15 answer
8/14 = 20/x giving the top side = 35 answer
Answer:
The equivalent expression to the given expression 4m-2+(-8m) is -2(2m+1)
That is 4m-2+(-8m)=-2(2m+1)
Step-by-step explanation:
The given expression is 4m-2+(-8m)
To find the equivalent expression to the given expression 4m-2+(-8m):
4m-2+(-8m)=4m-2-8m ( here using Associative property )
=-4m-2 ( adding the like terms )
=-2(2m+1) ( taking common term -2 in the above expression )
Therefore 4m-2+(-8m)=-2(2m+1)
Therefore The equivalent expression to the given expression 4m-2+(-8m) is -2(2m+1)
That is 4m-2+(-8m)=-2(2m+1)
