1. Because
info given:
Karim's dog = 15 pounds
Frank dog = 2x more pounds than Karim's dog + 1.5 pounds
(Karim) Equation 1: 15 = Frank
(Frank) Equation 2: 2w + 1.5
joining equation 1 and 2
15 = 2w + 1.5
Solve
15 - 1.5 = 2w
13.5 = 2w ÷ 2
w = 6.75
The three numbers are 23, 161, and 123.
1, 2, 4, 7, 8, 14, 28, and 56
4½ = 9/2
1 2/5 = 7/5
9/2 * 7/5 = 63/10 = 6 3/10
Dy/dx=4x/y2 this is what i got
hope this helps
