Substituting into the second expression,
Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65

Answer:
n = The number of can collected after lunch
Step-by-step explanation:
Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling.
From the question, the told number rod cans collected before lunch = n
We are told that :
At the end of the day, the total number of cans collected can be represented by the expression 173 + n .
The total number of cans = Number of cans collected before lunch + Number of cans collected after Lunch
Hence:
173 + n = 173 + Number of cans collected after Lunch
Therefore, the variable n = Number of cans collected after Lunch
