Answer: f(x) = 22x
Step-by-step explanation:
1.) Divide 132 by 6 weeks, to get the amount of time spent each week on homework.
<em>132 / 6 = 22</em>
2.) Create the equation. Because x represents the number of weeks and 22 minutes a week is spent on homework, the equation is as follows:
f(x) = 22x
Answer:
x = - 12/11
Step-by-step explanation:
Multiply by LCM (or LDC if you like that term better)
2 & 3 LCM = 6
6(3/2) x + 6(1/3)x + 5*6 = 3*6
9x + 2x + 30 = 18
11x = - 12
x = - 12/11
Answer:
Step-by-step explanation:
18y -30 -7y =25
solution
18y -30 -7y =25
so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue
18y -7y=25+30
when a negative is crossing an equal sign it turns positive and vice versa
so lets solve
11y=55
the one with the unknown will divide
11y/11=y
you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc
Then 55/11=5
so y=5
Thats the correct answer....
" the difference " means subtract
the difference between 5 and twice a number x is 1
5 - 2x = 1 <== ur equation
-2x = 1 - 5
-2x = - 4
x = -4/-2
x = 2 <== ur solution
Given:
The system of equations is
To find:
The correct statement for the given system of equations.
Solution:
On comparing the given equations and general form of linear equation, i.e., 
, we get
Here,
Since, 
, therefore, the two equations are equivalent and the system has infinitely many solutions.
Hence, the correct option is b.
