Answer:
-0.5 and negative one-half
-1/50 and -0.02
Step-by-step explanation:
-0.5 can be rewritten as -5/10. This can be simplified to -1/2 which is the same as negative one-half.
7/10 isn't equivalent to 11/20. If you multiply 7/10 by 2/2 to get the denominator of 20, it will become 14/20 not 11/20.
-1/50 in decimal form is -0.02 so -1/50 and -0.02 are equivalent.
0.15 and 1/5 aren't equivalent because 1/5 in decimal form is is 0.2, not 0.15.
9.) <span>1/2(4x-6)=11
</span>Multiply 4 and -6 by 1/2
2x-3=11
Add 3 to both sides
2x=14
Divide 14 by 2
Final Answer: x=7
10.) 2/3(6x-9)=-34
Multiply 6 and -9 by 2/3
4x-6=-34
Add 6 to both sides
4x=-34
Divide -34 by 4
Final Answer: x=-8.5
2.5y + 3x=7 (1st)
5x - 2.5y = 5 re-write -2.5y + 5x = 5 (2nd)
2.5y + 3x=7 (1st)
-2.5y + 5x = 5 (2nd)
---------------------------add
8x = 12
x = 12/8 = 1.5
2.5y + 3x=7
2.5y + 3(1.5)=7
2.5y = 7 - 4.5
2.5y = 2.5
y = 1
