Answer:
x = 1
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Translate</u>
"Five" = 5
"times" is multiplication
"difference" is subtraction
"twice" means 2 times something
"a number" = <em>x</em>
"is" means equal
"-10" = -10
<u>Step 2: Set up equation</u>
5(2x - 4) = -10
<u>Step 3: Solve for </u><em><u>x</u></em>
- Distribute 5: 10x - 20 = -10
- Isolate <em>x </em>term: 10x = 10
- Isolate <em>x</em>: x = 1
1) variable
2) value
3) absolute value (maybe)
4) natural numbers
5) whole numbers
6) integers
I think the answer is d. -11
Explanation:
Replace the variable x with 3 in the expression.
f(3)=-2•3-5
Multiply -2 by 3
f(3)=-6 -5
Subtract 5 from -6
f(3)= -11
Then the answer should be -11.
