Answer:
Step-by-step explanation:
1) 1 km = 1000 m
7.8 km = 7.8 * 1000
= 7800 m
2) 1 g = 1000 mg
1.6 g = 1.6 * 1000
= 1600 mg
You can think of "per cent" as meaning "divided by 100". Thus
.. 24% = 24/100
This fraction can be reduced by removing a factor of 4 from numerator and denominator:
.. 24% = 24/100 = 6/25
Answer:
=−2xy+3x+2y
Step-by-step explanation:
this is what i get in calculating
6 - 3(2x - 4) = 2(1 + x)
6 - 3(2x) + 3(4) = 2(1) + 2(x)
6 - 6x + 12 = 2 + 2x
6 + 12 - 6x = 2 + 2x
18 - 6x = 2 + 2x
<u> + 6x + 6x</u>
18 = 2 + 8x
<u>- 2 - 2 </u>
<u>16</u> = <u>8x</u>
8 8
2 = x
The answer is D.
