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:
Answer:
a =-6
Step-by-step explanation:
4a+5=2+3.5a
Subtract 3.5a from each side
4a-3.5a+5=2+3.5a-3.5a
.5a +5 = 2
Subtract 5 from each side
.5a +5-5 = 2-5
.5a = -3
Divide each side by .5
.5a/.5 = -3/.5
a =-6
5(2x+1) (2x-1) is what you get when you factorise this equation
