Answer: 1
Step-by-step explanation:
Answer:
x is 13
Step-by-step explanation:
x-2=11
then x = 11 +2
since the negative 2 will be crossing over the equal sign to turn positive
x= 13
Third angle = 180 - (6x+7) - (10x-3)
= 180 - 6x - 7 - 10x + 3
= 176 - 16x
just minus the sum of triangle by the 2 angles and you're left with the 3rd one
Answer:
-12
Step-by-step explanation:
To evaluate the expression the known value of a = -8 can be substituted in so the equation becomes -8 - 4.
From there the subtraction can be completed which equals -12. This can be visually seen on a number line if you look at -8 and move left 4 spaces.
