Answer:
Step-by-step explanation:
Mike is at the shop for school supplies. He sees some pencils he wants to buy. He sees that if he buys twelve of the same item, the store will take off $8. How much will twelve pencils cost at the store if one pencil is $5.99?
Equation: 12x-8
12x-8 = 
12(5.99) - 8 = 
71.88 - 8 = 
$63.88
Hope this helps:)
 
        
             
        
        
        
I think you have to find a common multiple for the denominators 5 and 8 which would be 40. so it would be 6/40 and 2/40. then I think, you  would add or multiple, depending on the situation, 6 and 2

Answer:

Given:
- area = 18 cm²
 - base = 6 cm
 - height = (h + 1) cm
 
Substitute the given values into the equation and solve for h:



expand using distributive property of addition 
:

subtract 3 from both sides:

divide both sides by 3:

<u>To verify</u>:
Half of the base is 3 cm.
If h=5, then the height of the triangle is 6 cm.
Multiplying 3 by 6 is 18.
This matches the given area, so we can verify that h = 5.
