<em>a = 5</em>
- Step-by-step explanation:
<em>a(2x + 3) = 9x + 15 + x</em>
<em>a(2x + 3) = 10x + 15</em>
<em>a(2x + 3) = 5(2x + 3)</em>
<em>a = 5(2x + 3)/(2x + 3)</em>
<em>a = 5</em>

Step-by-step explanation:
=(D-64)2
We move all terms to the left:
-((D-64)2)=0
We calculate terms in parentheses: -((D-64)2), so:
(D-64)2
We multiply parentheses
2D-128
Back to the equation:
-(2D-128)
We get rid of parentheses
-2D+128=0
We move all terms containing D to the left, all other terms to the right
-2D=-128
D=-128/-2
D=+64

Like two walls they touch the whole line
Answer:
1.994
Step-by-step explanation:
"Percent" means "per 100" or "over 100". To convert 199.4% to a decimal rewrite 199.4 percent in terms of per 100 or over 100.
199.4% = 199.4 over 100 or,
199.4%=199.4100
199.4 over 100 is the same as 199.4 divided by 100. Completing the division we get:
199.4 ÷ 100 = 1.994
Therefore, we have shown that
199.4% = 1.994
Simplified Conversion:
Remove the percent sign % and divide by 100.
199.4 ÷ 100 = 1.994
Shortcut Conversion:
Move the decimal point 2 places to the left and remove the percent sign %
199.4% becomes 1.994
