Step-by-step explanation:
ABC+DAB=180
DAB=180-115
DAB= 65
m<3+m<4=65
m<3=65-m<4
You have been given 4 degrees there, but it has not fallen. The answer is either A or B. Subtracting the conditional degree from 65. Find 3.
The answer is k-20
decreased means to take away/subtract, “k” is being subtracted by 20, therefore k-20
Hope this helps! have a wonderful day!

Answer:
x=1 y=19
Step-by-step explanation:
Let's solve your system by elimination.
−9x+y=10; 10x−y=−9
−9x+y=10
10x−y=−9
Add these equations to eliminate y:
x=1
Then solve x=1 for x:
x=1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
−9x+y=10
Substitute1forxin−9x+y=10:
(−9)(1)+y=10
y−9=10(Simplify both sides of the equation)
y−9+9=10+9(Add 9 to both sides)
y=19
Hope this helps, I don't really get the answer choices though....
Answer:
-def. In multiplication, the order doesn't matter.
Step-by-step explanation:
A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.
3 * 2 = 6
2 * 3 = 6
5 * 2 * 3 = 30
2 * 3 * 5 = 30
3 * 2 * 5 = 30
Thus,
edf, or
e * d * f
is the same as def,
d * e * f
e * d * f = d * e * f
edf = def
Thus, 12edf is the same as 12def. We can put this in our expression:
12edf - 13def
12def - 13def
Now, we can see that this will equal -1def or -def
12def - 13def
-1def
-def
Answer: -def. In multiplication, the order doesn't matter.
