Step-by-step explanation:
<u>Step 1: Define</u>
(4x + 2)(x - 5) / 2
x = 2
<u>Step 2: Evaluate</u>
- Substitute: (4 · 2 + 2)(2 - 5) / 2
- Parenthesis - Multiply: (8 + 2)(2 - 5) / 2
- Parenthesis - Add: 10(2 - 5) / 2
- Parenthesis - Subtract: 10(-3) / 2
- Multiply: -30 / 2
- Divide: -15
Answer:
X = > 12 because 15 - 3 = 12 and if X was more than 12 it would be wrong.
Step-by-step explanation:
F(x) = 3x-6
add 6 to each side
6=3x
dived each side by 3
2=x
Answer is 285
Reason
When you divide by a fraction, you flip the fraction and multiply
So 190 divided by 2/3 becomes 190 x 3/2
Factor 190 x 3/2, multiply across
190 x 3 = 570 then
570 divided by 2 = 285
