n, n + 2, n + 4 - three consecutive even integers
3n = 2(n + 4) + 4 |use distributive property
3n = (2)(n) + (2)(4) + 4
3n = 2n + 8 + 4
3n = 2n + 12 |subtract 2n from both sides
n = 12
n + 2 = 12 + 2 = 14
n + 4 = 12 + 4 = 16
Answer: 12, 14, 16.
Answer:
2:3
Step-by-step explanation:
the ratio is simplified to 2:3
Answer:
12/4=3 or 12/3=4
Step-by-step explanation:
because multiplication is the opposite of division
2x+2(3x-2)+4-2(3x+8)
According to PEMDAS Parentheses Exponents Multiplication Division Addition Subtract, you must do the numbers in the parentheses.
2x+2(3x-2)+4-2(3x+8)
| |
2x+6-4+4-6x+16
Since there are no exponents, multiplication, and addition we do subtracting and adding. Which ever comes first in the equation.
2x+6-4+4-6x+16
Subtract the variables.
2x -6x = -4x
-4x+6-4+4+16
We cannot add variables and numbers together.
6-4=2
2+4=6
6+16=22
22 is a positive number so the answer is...
-4x+22
Hope it helps!
if you need it solved,
Subtract 206 from both sides.
Divide by 8 on both sides.
Answer is 12.25
