Answer:
- 35 5-lb weights
- 25 3-lb weights
Step-by-step explanation:
Let t and f represent the numbers of three- and five-pound weights. The problem statement tells us ...
f + t = 60
f - t = 10
Adding these two equations, we get ...
(f +t) +(f -t) = (60) +(10)
2f = 70 . . . . . eliminate parentheses
f = 35 . . . . . . divide by 2
She has 35 5-lb weights, and 25 3-lb weights.
Since x is intersecting y, it will be XnY =(0, 10)
-3x+(-15)+8=2x+8-6
45x+8=2x+2
not equal
46 is your correct answer bc 30 plus 16 is 46
