Answer:
m=5
Step-by-step explanation:
1) Add 2m on both sides simplify
(-5+9m-20=20)
2) Add 20 on both sides to simplify
(-5+9m=40)
3) Add 5 on both sides to simplify
(9m=45)
4) Divide by 9 on both sides to isolate m.
(m=5)
5) You have approached your solution.
Hey it's me again if you like my answer please mark it as the brainliest that would be much appreciated. Thanks! :D
Answer:
X = 35.7 Y=54.3
Step-by-step explanation:
Let the 2 angles be called X and Y were X is the smaller angle
we know that both angles are complementary therefore
X+Y=90
X = Y - 18.6 ( Given )
Y - 18.6 + Y = 90 ( substitution)
2Y = 90 + 18.6
Y = 108.6/2
Y=54.3
X= Y-18.6= 54.3-18.6 = 35.7
Check : X + Y = 35.7+54.3=90
Answer:
8x+6y
Step-by-step explanation:
add the coefficients of like terms with the same variable
Answer:
11
Step-by-step explanation:
187=17r
Divide 17 on both sides so that "r" is by itself and can be solved
187/17=r
11=r
Hope this helps!
