Answer:
a= k=15 c= m=48/7
Step-by-step explanation:
for a.
first, collect like terms. calculate.
2k- 10 = 20
move the constant to the right (10)
2k = 20 + 10
2k = 30
divide both sides.
k= 15.
for c.
first calculate.
12= 3m - 2/3m - 4
multiple both sides.
36= 9m - 2m - 12
collect like terms.
36= 7m - 12
move like terms.
-7m= - 12 - 36
calculate.
-7m= - 48
divide both sides.
m=48/7

Answer:
D. 68+(6x+4)=180
x = 18
Step-by-step explanation:
"Supplementary angles" are angles that add up to 180°
So we add the twi angles 68+(6x+4) and that equals to 180°.
68 + 6x + 4 = 180
add 68 and 4
72 + 6x = 180
subtract 72.
6x = 108
divide by 6.
x = 18
Step-by-step explanation:
because 
. 10 is the square root of 100, which means that 10 multiplied by itself (10×10=
) is equal to 100. So, when you are trying to find the square root of a number, the square root is itself multiplied by itself.
