Answer:
Kayla and Maddy will be in the same level in 4 days.
Step-by-step explanation:
Kayla: y = 6x + 12
Maddy: y = 2x + 28
6x + 12 = 2x + 28
Subtract 2x from both sides;
4x + 12 = 28
Subtract 12 from both sides;
4x = 16
Divide both sides by 4;
x = 4
Answer:
A = 28
B = 87
Step-by-step explanation:
18 + 10 = 28
103 -16 = 87
Px + qy = r
2px - qy = 2r
----------------add
3px = 3r
x = 3r/3p
x = r/p
Answer:
82 units
Step-by-step explanation:
7 x 3 = 21
21 x 2 = 42
7 x 2 = 14
14 x 2 = 28
2 x 3 = 6
6 x 2 = 12
42 + 28 + 12 = 82
