X = 250 mg tabs
y = 500 mg tabs
2200x + 1800y = 39200....multiply by -1
2200x + 2200y = 44000
--------------------------------
-2200x - 1800y = - 39200 (result of multiplying by -1)
2200x + 2200y = 44000
--------------------------------add
400y = 4800
y = 4800/400
y = 12...... the 500 mg tabs (y) costs $ 12 per bottle
2200x + 2200y = 44000
2200x + 2200(12) = 44000
2200x + 26400 = 44000
2200x = 44000 - 26400
2200x = 17600
x = 17600/2200
x = 8 <== the 250 mg tabs (x) costs $ 8 per bottle
Answer:
The answer would be 20 weeks
Step-by-step explanation:
Because, if she makes $5 per week you would just divide 100 by 5 and get 20 and to check you would multiply your answer to see if it equals the amount he/she would want to amount to. Hope this helps! Happy learning!
Answer:
z = 15/30 = 3/6
Step-by-step explanation:
1/5z - 5/6 = - 4/5z - 1/3
1/5z + 4/5z = - 1/3 + 5/6
5/5z = - 2/6 + 5/6
5/5z = 3/6
z = 3/6 / 5/5
z = 3/6 * 5/5
z = 15/30
