Answer:
a) 39 b) 17
Step-by-step explanation:
12x - 9
12(4) - 9
48 - 9
39
d/15 + 13
(60)/15 + 13
4 + 13
17
Answer:
This would be false
Step-by-step explanation:
Exponents can't be negative
• Increased by 3
n+3
• Twice the number
2(n+3)
• Three times the number
3n
• Final result
2(n+3)-3n
First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.
3 + 4x = 5x
we can subtract 4x from both sides to get our final answer,
3 = x, or x = 3. :)
