Answer:
Length = 56
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
Perimeter = 2L + 2W
2L + 2W = 204
2L + 2(46) = 204
2L + 92 = 204
Subtract 92 from both sides
2L = 112
Divide both sides by 2
L = 56
Length = 56
Answer:
First box: 2
Second box: 30
Third box: 42
Step-by-step explanation:
5 sixes means 5 · 6, which equals 30. An unknown amount of sixes equals 12, which is 2 because 2 · 6 = 12.
30 + 12 = 42
7 · 6 = 42, so 42 is the answer.

Answer:
x = 3
, y = 5
Step-by-step explanation:
Solve the following system:
{3 y - 7 x = -6 | (equation 1)
3 y - 3 x = 6 | (equation 2)
Subtract 3/7 × (equation 1) from equation 2:
{-(7 x) + 3 y = -6 | (equation 1)
0 x+(12 y)/7 = 60/7 | (equation 2)
Multiply equation 2 by 7/12:
{-(7 x) + 3 y = -6 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{-(7 x)+0 y = -21 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by -7:
{x+0 y = 3 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = 3
, y = 5
