Answer:
answer is 69 degree
Step-by-step explanation:
a+33+78=180 degree
a+111=180
a=180-111
a=69
To find 1/4 of 12 you would divide 12 by 4 to get 3. To find 1/3 of 12 you would divide it by 3 to get 4. 4 is greater than 3 so therefore 1/3 is greater.
Answer: 6(1,2,3)
Step-by-step explanation:
<span>Simplifying
2n + -7 + 3(4n + -3) = 0
Reorder the terms:
2n + -7 + 3(-3 + 4n) = 0
2n + -7 + (-3 * 3 + 4n * 3) = 0
2n + -7 + (-9 + 12n) = 0
Reorder the terms:
-7 + -9 + 2n + 12n = 0
Combine like terms: -7 + -9 = -16
-16 + 2n + 12n = 0
Combine like terms: 2n + 12n = 14n
-16 + 14n = 0
Solving
-16 + 14n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + 14n = 0 + 16
Combine like terms: -16 + 16 = 0
0 + 14n = 0 + 16
14n = 0 + 16
Combine like terms: 0 + 16 = 16
14n = 16
Divide each side by '14'.
n = 1.142857143
Simplifying
n = 1.142857143</span>
Answer:
x= -20
Step-by-step explanation:
So the first thing you would want to do is multiply 2 on both x and -50. After that you will end up with 7x = 2x - 100. Then you will need to subtract x on both sides getting 5x = -100. Finally you will need to divide 5 on both sides getting x = -20
