Answer:
b should be the correct answer.
Step-by-step explanation:
-1/4 i think, Y1-Y2/X1 -X2= the slope . -9-3= -12 and -6 - (-9)= -6 +9= 3. So simplify 3/-12 makes -1/4.
Answer:
$200
Step-by-step explanation:
Let X be the amount of Christmas money he had at the beginning.
He put 65% of X in the bank. This is 0.65x
He has $70 left which is equal to 0.35x
We need to write an equation to find the value of x.
70 = 0.35x
Divide by 0.35 to find the value of x.
70/0.35 = 0.35x/0.35
200 = x
He received $200 for Christmas.
Writing this statement symbolically, we get:
n
--- - 5 = 8
2
Adding 5 to both sides, we get n/2 = 13. Then n = 26.
The answer you are looking for is X = 21.
Since supplementary angles equal 180, you'd first need to subtract 48 from 180. This gives you 132. Next, you'd divide 132 by 6 to get 22. Since x is in the parenthesis with "+ 1", you'd subtract 1 to give you x (21).
I hope this helps!
