Answer:
Step-by-step explanation:
<h3>The first line</h3>
- Line x - y > 5 ⇒ y < x - 5
<u>This line has positive slope and the y-intercept is -5, shaded area is below the line, covers the areas:</u>
<h3>The second line</h3>
- Line x + 2y < -6 ⇒ 2y < - x - 6 ⇒ y < -1/2x - 3
<u>This line has negative slope and the y-intercept is -3, shaded are is below the line, covers the areas:</u>
<u>Solution of the system is the intersection of the areas:</u>
Let x=grams of 70% alloy:
0.70x+16×0.20=0.30(x+16)
0.70x=0.30x+4.8-3.2
0.40x=1.6
x=1.6/0.4=16/4=4g
4 grams of 70% alloy are needed.
Answer:
make the denominators ( bottom number ) the same and whatever u do to that do to the top
Step-by-step explanation:
e.g ½ - ⅓
make the common denominator 6
to get from 2 to 6 u times by 3 so it wud be 3/6
and then to get from 3 to 6 u times by 2 so do the same to the numerator (top number) so u get 2/6
3/6 take away 2/6 is 1/6
