Answer:
b
Found the answer, its B. 3/2!
Answer:
I'm not too sure which one you need, so choose what answer needs to go in the box!
JL= 44.5
JK=23.3
KL=23.3
Step-by-step explanation:
Since JK and KL are equal to eachother, we have to find the missing variable through them. You want to choose one side to have the variable number and the other side for the normal numbers. I can't really explain this next bit, so I'll show the math below:
V N
4x - 10.7 = 2x + 6.3
+10.7. +10.7
_________________
4x = 2x + 17
-2x -2x
2x = 17
So, once there is only one variable number and one normal number left, what do you do? You divide the variable by the number it's worth and carry the division to the normal number.
2x = 17
÷2. ÷2
_______
x = 8.5
So, 8.5 is our number we need. We then just insert it into all the equations to get the numbers.
4 × 8.5 = 34
34 - 10.7 = 23.3
Since JK and KL are equal, they are both 23.3.
5 × 8.5= 42.5
42.5 + 2 = 44.5
JL=44.5
Answer:15x + 13 it is simplifyi
You need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.
Step-by-step explanation:
Since the functions f(x) and g(x) are missing in the question, I will explain it with my own example and you can solve it with your functions.
Let f(x)= 2x^2+3x+4
and g(x) = 4x^2+9x-6
We need to find f(x)-g(x)
Solving:
f(x)-g(x)=2x^2+3x+4-(4x^2+9x-6)
f(x)-g(x)=2x^2+3x+4-4x^2-9x+6
f(x)-g(x)=2x^2-4x^2+3x-9x+4+6
f(x)-g(x)=-2x^2-6x+10
So, you need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.
