Answer: x=3
Step-by-step explanation: First we do distributive property in the parentheses. Next we subtract both sides by 6. Lastly we divide both sides by 3. Algebraic Rules!!!
Work:
3(x+2)=15
3x+6=15
3x+6-6=15-6
3x=9
3x/3=9/3
x=3
Answer:
(c) 
Step-by-step explanation:
Given
The attached graph
Required
Find h(3)
The formula to use in solving this is:

Substitute 3 for x

From the attached graph, the value od x = 3 points to the value of y = 1.
So, we have:

0.018 will be 18/1000 = 9/500
