Answer:
2a = 108
Step-by-step explanation:
the 3 angles of the triangle add to 180
lets call the unknown angle in the triangle y
a+10 + y + 44 = 180
we also know that 2a+ y = 180 because it makes a straight line
solve this for y by subtracting 2a from each side
2a +y = 180
y = 180 -2a
now we can substitute this into the triangle equation
a+10 + y + 44 = 180
a+10 + 180 -2a + 44 = 180
combine like terms
-a +234 = 180
subtract 234 from each side
-a = --54
divide each side by -1
a =54
the exterior angle is 2a
2* 54
108
We Know That This Number Is:
Two-Thousand-Seven-Hundred-Eighty-Three.
So, This tells Us That The 2 Is The Thousandths Place.
So, We Also Know That The Value Of 2 In The 2nd One Is 200. This Means That The value of the first one is 10 times larger than the value of the 2 in the second one!
<h3><u>The value of y is -7.</u></h3><h3><u>The value of x is 8.</u></h3>
First we need to rearrange these equations so they line up properly.
6x - 2y = 62
-x + 2y = -22
Add equations together.
5x = 40
Divide both sides by 5.
x = 8
We can plug this value in to find the value of y.
6(8) - 2y = 62
48 - 2y = 62
Subtract 48 from both sides.
-2y = 14
Divide both sides by -2.
y = -7
All you would have to do is divide 1110 by 35 to figure out how many doses are in the bottle of cough syrup and we get 31 So there are 31 doses
