Correct answers are:
1) 1/3 (NOT 3/10). .3 repeating is not 3/10, 3/10 is .3.
2) 1/8. To solve, .125 has three places, so use 1000. 1000/125 is 8, that is your denominator. 125/125 is 1 is your numerator.
3) 1/6 (divide 100/16, which is 6 ¼ - round to 6. If you carry this out to 1,000,000/166,667, it is very close to 6.
4) 1/10
5) 2/3 (NOT 3/5)
6) 1/5 (2/10 reduced to 1/5)
7) 3/4 (75/100 reduced)

Answer:
x=17
Step-by-step explanation:
Answer:
x=5
Step-by-step explanation:
3x+1= 4x+(-4)
-4×+1= -4x-1 combine like terms
-1x= -5 divided by -1
x= 5
Answer:
x = -3
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x - y = -12 | (equation 1)
-x - y = 3 | (equation 2)
Add 1/4 × (equation 1) to equation 2:
{4 x - y = -12 | (equation 1)
0 x - (5 y)/4 = 0 | (equation 2)
Multiply equation 2 by 4/5:
{4 x - y = -12 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x - y = -12 | (equation 1)
0 x+y = 0 | (equation 2)
Add equation 2 to equation 1:
{4 x+0 y = -12 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -3 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -3
, y = 0
