Answer:
36 degrees
Step-by-step explanation:
There's 180 degrees in a triangle.
Since they're supplementary angles, we do 180-142=38.
We now know that 106+38+x=180.
Solve for x: x=36
Answer:
Step-by-step explanation:
(-3/9 + 4/3)+ a = 0
first solve our terms in the parentheses by adding them
to do this we have to find the lcd ( lowest common denominator)
9 works for both so I multiply both halves of 4/3 by 3 to get my denominator to 9 the other fraction is already at a denominator of 9 so we leave it alone
(-3/9 + 12/9)+ a=0
then add
(9/9)
9/9=1 SO WE SIMPLIFY
1+a=0
now we isolate our variable (a) to do this we subtract 1 from both sides of our equals sign to get the answer
a=-1
hope this helps
-5n-8(1+7n)=8
Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61
Hope I helped! :)
