Answer:
x + y = 83
Step-by-step explanation:
When it says opposite angles are supplementary and yo use A as a reference point it means
supplementary means they add to 180
so
A + C = 180
so
2x + 4 + 2y + 10 = 180
now simplify
2x + 2y + 14 = 180
- 14 -14
2x + 2y = 166
/2 /2
x + y = 83
Answer:
30 hours
Step-by-step explanation:
One.
x=12
I have to type more words or I can't submitttt so yeah..
65 is 52% of 125.
I do the IS over OF operation when finding a percentage, where you multiply the is by 100 then divide by the percentage.
Answer:
m = 1/3
b = -6
Step-by-step explanation:
How to calculate slide (m):

x1 = 0
x2 = -12
y1 = -6
y2 = -10
If we put in the values:

Subtracting a negative number is the same as adding it:

-6 + 10 = 4 and 0 + 12 = 12 so now we have this:

Lets simplify:
4 and 12 can both be divided by 3:

3 and 1 are prime numbers and cannot be simplified further.
Now we know that m=1/3
Since:
y = mx + b
y = -6
x = 0
m = 1/3
Then:
-6 = 1/3*0 + b
1/3*0 is 0, so we can just remove that part:
-6 = b
that means b is equal to -6
