Step-by-step explanation:multiply the first dogs weight by 3.8
No spaces? like t h i s? or like thiiiss??? is this bugging you ????
anyway
use elimination
multiply secn equation by -1
-3x-2y=-6
add to other equation
-3x-2y=-6
<u>4x+2y=10 +</u>
1x+0y=4
x=4
sub back to solve for y
3x+2y=6
3(4)+2y=6
12+2y=6
minus 12 both sides
2y=-6
divide 2
y=-3
(4,-3)
Answer:
<h2>The answer is 314.96 g</h2>

The mass is
mass = 254 × 1.24
We have the final answer as
<h3>314.96 g</h3>
Hope this helps you
