Answer:
-8x + 146
Step-by-step explanation:
Step 1: Write out expression
3(58 - 6) - 2(4x + 5)
Step 2: Parenthesis
3(52) - 2(4x + 5)
Step 3: Multiply
156 - 2(4x + 5)
Step 4: Distribute
156 - 8x - 10
Step 5: Combine like terms (constants)
-8x + 146
So,
10% is also known as one-tenth.
If 5 is one-tenth of something, that means that we can multiply 5 by 10 to get ten-tenths of that something.
5 * 10 = 50
The number is 50.
As you can see, this is a negative slope. It goes down three and over four, as seen on the x and y intercepts. The answer kind of pops out at you.
