4(2x - 1) + 3 When x=6Evaluate
2 answers:
Answer: 47
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
x = 6
<u>Given expression</u>
4 (2x - 1) + 3
<u>Substitute values into the expression</u>
=4 [2 (6) - 1] + 3
<u>Simplify by multiplication</u>
=4 (12 - 1) + 3
<u>Simplify by subtraction</u>
=4 (11) + 3
<u>Simplify by multiplication</u>
=44 + 3
<u>Simplify by addition</u>
=

Hello,
1 .65 + 0.20(65) = 65 + 13 = 78
(65 - 60) / 65 = 5/65 = 0.0769 x 100 = 7.69 rounds to 7.7 % decrease compared to the 65 pizza's sold yesterday
2. I posted a file to help you on this question!
3. <span>Find principal by using the formula </span><span>I=P⋅i⋅t</span><span>, where </span>I<span> is interest, </span>P<span> is total principal, </span>i<span> is rate of interest per year, and </span>t<span> is total time in years.
