Answer:
16/21
Step-by-step explanation:
We are given the equation 3x(5 + 2) = 16.
By order of operations, let's add the two numbers in the parentheses first:
3x(5 + 2) = 16
3x(7) = 16
Now, we must multiply 3x by 7:
3x * 7 = 16
21x = 16
Divide both sides by 21:
x = 16/21
The answer is thus 16/21.

Equality Properties
Step-by-step explanation:
<u>Step 1: Define Inequality</u>
3x + 1 < 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 1 on both sides: 3x < 9
- Divide 3 on both sides: x < 3
Here we see that any value <em>x</em> smaller than 3 would work as a solution to the inequality.
