4) 21
5) 36
6) 29.25
I used porpotions on all of these.
Sorry I don't remember the units.
Well, it says that 34 kids like physics and since there is 100 students, we know 34% of the kids like physics. This means 66% like biology.
1. 81 1/2 = 163/2
2. 32 1/5 - 64 1/3 =
483/15 - 965/15 =
-482/15 or -32 2/15
3. 16 1/4 = 65/4
4. 49 1/2 + 27 1/3 =
99/2 + 82/3 =
297/6 + 164/6 =
461/6 or 76 5/6
Answer:
See below:
Step-by-step explanation:
So, for starters, g(x) is just a fancy way of saying that it is a function, it's basically used as
and you can usually use g(x) or y whenever you want unless its a special situation.
So we can replace g(x) with y as there aren't any other functions we need to deal with.
y = 3x + 2
y = 11
Now that its simplified, we can see its a simple problem
After combining, we get 11 = 3x + 2
After solving, we get x = 3
Answer:
For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.
Step-by-step explanation:
Given equations are:
4x + 5y = 10
Ax + By = 16
The general form of linear equation in two variables is given by:

Here a, b and c are constants and x,y are variables.
In the given equations, after comparing with the general form

"In order for a system of equations to have infinity many solutions,
"
Putting the values we get

Hence,
For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.
