Answer:
∠ Y = 45°, ∠ X = 135°
Step-by-step explanation:
Since the 2 angles are supplementary, then
X + Y = 180 ← substitute X = 3Y
3Y + Y = 180, that is
4Y = 180 ( divide both sides by 4 )
Y = 45
and
X + Y = 180, so
X + 45 = 180 ( subtract 45 from both sides )
X = 135
Thus
∠ X = 135° and ∠ Y = 45°
Answer:
Step-by-step explanation:
So for this we have to find the percentage by using 'percentage of error'
If at first it was 15 then it went up to 19 we have to subtract 15 - 19= -4
Ignore the negative. Now divide= 4/19= 0.21
The size went up by 21%
648 divided by 8 is 81.
64 goes into 8 8 times (8*8)
8 goes into 8 1 time (8*1)
436 hamburgers and cheeseburgers sold Wednesday.
64 fewer cheeseburgers.
436/2= 218
218-64= 154
154 cheeseburgers were sold Wednesday.
