M < PQS + m < RQS = 180° because they are supplementary angles.
Therefore:
(3x + 3) + (x + 19) = 180
3x — 3 + x + 19 = 180
4x + 16 = 180
Subtract 16 from both sides
4x — 16 = 180 — 16
4x = 164
Divide both sides by 4:
4x/4 = 164/4
x = 41
Therefore, the correct answer is x = 41
The system should look like this:
eh + b = 243
eh - b = 109
205 liters in 5 1/4 minutes
m = 5 1/4
20 (5 1/4) = 105
100+105= 205
0.125 the first one, even though im not sure.
