Answer:
D. NM=12; mK=70°
Step-by-step explanation:
KN≈KM so they have the same 55° and then
180°-55°-55°=70° and
6*2=12
X=15
Hope this helps I had the same problem. That’s what I got.
OK first change 3 3/4 to an improper fraction and that will give you 15/4. so you got that part right. Next, change the division sign to multiplication. then flip the 1/2 to 2/1. Then multiply 15 times 2 and that will give you 30. Then multiply 4 times 1 and that will give you 4. then you will have an answer of 30/4. Finally, since you a have a big number over a small number you divide 30 by 4 and that will give you 7 1/2. So it turns out that your little cheat sheet is wrong because when you check your answer you should go on Math-way to check it. Also, a little background about me is that I am in 8th grade and I am taking algebra 1 too.
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y =
x + 4 → (1)
-
x + y = - 5 → (2)
Substitute y =
x + 4 into (2)
-
x +
x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
The answer is F.)
