Answer:
x = 105
y = 64
Step-by-step explanation:
Inside the four sided figure, the angles must add to 360. So 121+70+x+y = 360. You also know that a straight line is 180. This means 116 + y = 180. Using them together you can solve for the variables. Begin by substituting the equation 116 + y = 180 into the other equation.
116 + y = 180 converts to y = 180-116 = 64.
Substitute y = 64 into 121 + 70 + x + y = 360.
191 + x + 64 = 360
255 + x = 360
x = 105
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
The associative property states that we can add numbers in any way we want to still get the same sum, so the parenthesis here can essentially be tossed out to get 3x+2-5=3x-3. However, make sure, for example, that you don't add x and 1 together in 3(x)+1 as you still have to multiply the x with 3 before adding the 1 according to PEMDAS
