The format that this si used in is Y=MX+B. Y means the y cordinant and X means the x cordinant. B is the y intercept, or where the line goes through the y line. In this case B is 2/3. M is the slope. The rise is -5 and the run is 2 in this case. The slope is -5/2.
Answer:
Sorry i need to see answers, so i need to answer questions
Step-by-step explanation:
This is a mixture problem.
mass1 * karat1 + mass2*karat = total mass * total carat
Total mass = 200g.
Total karat = 14.
Let the 9 karat gold to be mixed be x. The 18 karat would weight (200 - x). Since the total = 200g.
9*x + 18*(200 -x) = 14*200
9x + 18*200 - 18*x = 14*200
18*200 + 9x - 18x = 14*200
3600 - 9x = 2800
3600 - 2800 = 9x
800 = 9x
9x = 800
x = 800/9
x ≈ 88.89
Therefore 88.89 grams of 9 karat gold must be mixed.
So mother is 1 and 3/4 times son
son=3
subsitute
1 and 3/4 times 3
convert 1 to 4/4
4/4 and 3/4=4/4+3/4=7/4
7/4 times 3/1=21/4=5 and 1/4
answer is mother is 5 and 1/4 foot tal
GX, FW, and YH. That should be the main ones.
