Answer:
The answer to your question is x = 10
Step-by-step explanation:
Use proportions to solve this problem
Given (x + 4)/8 = (2x + 1)/12
12(x + 4) = 8(2x + 1)
Expand
12x + 48 = 16x + 8
Group like terms
12x - 16x = - 48 + 8
Simplify
-4x = -40
Solve for x
x = -40/-4
Result
x = 10
No, it's one or the other.
Answer:
'Twice the sum of a number and 5' can be translated into variable expression such as:
Step-by-step explanation:
Given the phrase
<em>Twice the sum of a number and 5</em>
First, let us breakdown the English Phrase
Let the number be = n
The sum of a number 'n' and 5 = n + 5
now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.
Thus,
'<em>Twice the sum of a number and 5</em>' can be translated into variable expression such as:
I'm not sure what the answer is but I'll add subtract and multiply something. Remember PEMDAS for the order of operations
10 x 2 - 5
= 20 - 5
= 15
That's an example
