Answer:
don't know
Step-by-step explanation:
Ab + bc = ac
3x + 4 + x + 3 = 5x + 2
4x + 7 = 5x + 2
7 - 2 = 5x - 4x
5 = x <==
ab = 3x + 3....3(5) + 4 ....15 + 4 = 19
bc = x + 3 ...5 + 3 = 8
ac = 5x + 2....5(5) + 2.....25 + 2 = 27
Lets take this equation step by step. (set up the equation)
12 + 0.35x = 20.05 (first we should subtract 12 from both sides.)
- 12 = -12 (Now the 12 on left side cancels out. And we solve the right)
0.35x = 8.05 (now divide both sides by 0.53 to isolate the x)
÷0.35 = ÷0.35 ( Now the left side cancels out. And we solve the right.)
x = 23 (we have found our answer!)
So your answer is D. 23
Good Luck! :)
