The difference of a number and 5 = n - 5
Twice that = 2(n - 5)
‘is’ is the equal sign, so the expression before is equal to 7.
Equation: 2(n - 5) = 7
Answer:
Step-by-step explanation:
Because if you add 18x to both sides of the equation, you get 0 = -18
Step-by-step explanation:
When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
Answer: 30% of 500 is 150.
