Answer:
1.09
Step-by-step explanation:
"Percent" means "per 100" or "over 100". To convert 109% to a decimal rewrite 109 percent in terms of per 100 or over 100.
109% = 109 over 100 or,
109%=109100109 over 100 is the same as 109 divided by 100. Completing the division we get:
109 ÷ 100 = 1.09
Therefore, we have shown that
109% = 1.09
Simplified Conversion:Remove the percent sign % and divide by 100.
109 ÷ 100 = 1.09
Shortcut Conversion:Move the decimal point 2 places to the left and remove the percent sign %
109% becomes 1.09
Alright so, in order to solve an equation, you must have the unknown by itself.
So, we first subtract 7 from both sides and get a new equation.
-6x = 72
Now we divide by -6 so that x is by itself.
x = -12.
Now, -12 is a *possible* solution to the equation. The way to find out is to check. Checking the answer means "plugging in" the number into the equation, and seeing if it solves. so.
-6 * -12 + 7 = 79
72 + 7 = 79
79 = 79
So, since the answer checked out, -12 is a solution to the equation.
Hope this helps.
A = -17/6
B = -1/2
C = 17
D = 17/6
Answer:
x= -17/6
Step-by-step explanation:
10=-9/2x-7-3/2x
multiply all by 2
20=-9x-14-3x
add -9x to -3x
20=-12x-14
replace 20 with -12x and put -12x as a positive
12x=-14-20
add -14 to -20
12x=-34
divide both sides by 12
x= -17/6
Answer:
-6
Step-by-step explanation:
This means what value can I plug into -3x-8 so that I get output 10.
g(x)=-3x-8
g(a)=-3a-8
So we are going to solve g(a)=10 for a.
g(a)=10
-3a-8=10
Add 8 on both sides:
-3a =18
Divide both sides by -3:
a =-6
Check it!
g(-6)=-3(-6)-8=18-8=10 and it's good! :)
6x+4y=68
