Answer:
x=1/7
Step-by-step explanation:
x/2+x/5=1
make same denominators;
5x/10+2x/10=1
simplify;
7x=1
x=1/7

Step-by-step explanation:
Answer:
1) after 4 weeks, Lin has more with $65
2) after 3 weeks they both have same amount
Step-by-step explanation:
let 'w' = number of weeks
1) <u>equation for Han</u>: y = 100 - 15w
y = 100 - 15(4)
y = 100 - 60
y = $40 after 4 weeks
<u>equation for Linn</u>: y = 25 + 10w
y = 25 + 10(4)
y = 25 + 40
y = $65 after 4 weeks
2) 100 - 15w = 25 + 10w
75 - 15w = 10w
75 = 25w
w = 3 weeks
You would first find out the greatest common factor of 204 and 306 which is 102
204 divided by 102 which is 2
306 divided by 102 which is 3
So the answer is 2/3
