The phrase "the sum of four and twice a number is 12" can be translated into an algebraic expression as: 4 + 2x = 12 or 2x + 4 = 12.
<h3>How to Translate a Phrase into an Algebraic Expression?</h3>
To translate the phrase into an algebraic expression, we can use a variable to represent the unknown number.
Let the unknown number be represented as: "x".
"Sum" means addition, which would be represented with the symbol, "+".
"Twice" means times 2.
Therefore, we can translate the given phrase into an algebraic expression as follows:
"twice a number" is translated as: 2x
The sum of four (4) and twice a number (2x) is translated as: 4 + 2x or 2x + 4.
Therefore, the whole phrase "the sum of four and twice a number is 12" would be translated into an algebraic expression as: 4 + 2x = 12 or 2x + 4 = 12.

Answer:
16⅜ cups
Step-by-step explanation:
Start by getting the same denominator on both fractions and by eliminating the mixed fraction. So our problem is:
15¾ cups + ⅝ cups = ?
15¾ = 63/4 = 126/8
126/8 + ⅝ = 131/8 = 16⅜
Answer:
Correct answer not shown on the options.
y = -(1/2)+1
Step-by-step explanation:
Let's find an equation in the format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
The slope can be calculated as the Rise/Run of the line between the two given points (-6,4) and (-2,2):
Rise = (2 - 4) = -2
Run = (-2 - (-6)) = 4
Slope = Rise/Run = -2/4 or -(1/2)
In fact, the actual full equation is y= -(1/2)x+1 (See attached graph).
None of the options have a slope of -(1/2). Either the information on the two points or the options are incorrect.
