Answer:
the answer is 120.6 (:
Step-by-step explanation:
<span>2(4x - 12) + 3x = 6x + 1
Distribute.
8x - 24 + 3x = 6x + 1
Combine like terms.
11x - 24 = 6x + 1
5x = 25
x = 5

Answer: 13
Step-by-step explanation:
I used Pythagorean theorem to solve this problem. As DC and AD is 12 and 5, you would do 12²+5²= c². 12²= 144 and 5²= 25. 144+25= 169. It doesn't end there. Do the square root of 169 ---> √169=13.
Solve the lower equation first
+12 on each side
7x=51
divide by 7
x=51/7
then use that to solve the upper equation
The answer would be 9.9
Pemdas
9.7-2.4= 7.3
2.6+7.3 = 9.9
