True
Step-by-step explanation:
after cross multiplication
Both will be 5a=2b
Answer:
The required inequality is: 12 ≤ 3x < 21
Step-by-step explanation:
We are given: three times a number is greater than or equal to 12 and less than 21
We need to answer following questions:
1) The inequality translated in numerical form
Let number = x
12 ≤ 3x < 21
2) Your work solving the inequality
We need to find value of x. Divide the inequality by x
4 ≤ x < 7
3) The solution graphed on a number line
It is shown in figure attached.
4) The solution in set notation
The set notation is: Considering x belongs to natural numbers N
{∀ x|x∈N, 4 ≤ x < 7}
5) The solution in interval notation
The interval notation is: [4,7)
because we have 4 less than equal to x and x is less than 7
Statements. Reasons
2(x-15) + 4 = 0. Given
2x-30+4=0. Distributive Property
2x+4=30. Addition Property
2x=26. Subtraction Property
X=13. Division Property
Not sure if you need to add equality at the end but that depends on you
