Answer:
t = 
Step-by-step explanation:
Given
D = M + Mrt ( subtract M from both sides )
D - M = Mrt ( divide both sides by Mr )
= t
Answer:
ok so 3-1.7=1.3
Step-by-step explanation:
this is bc 3-1=2-0.7=1.3
Hello!
To solve, we want to isolate the x on one side of the equation. We can use inverse operations to put numbers on the other side to find x.
First we undistribute our parentheses.
12x-66+15=21
We subtract 15 from both sides (it cancels out the 15 on the left side, making it 0).
12x-66=6
Now we add 66 to both sides, as -66+66=0
12x=72
Finally, we divide both sides by 12.
x=6
I hope this helps!
The answer would be 34.8 I’m pretty sure
Answer:
We do not have the equation for the part B, so we can not aswer it correctly.
But i will give a general answer.
We could have infinite answers always when we have more variables than linear independent equations:
This is, if we have one variable, x, we can have infinite solutions if we have no equations (or equations with no restrictions for our variable)
So if we have an equation like:
x*4 = √16*x
you can see that both sides of the equation are exactly the same, so this equation actually does not have any value, and x could take infinite different values and the equation will remain true.
If we have two variables, x and y, we will have infinite solutions if we have only one equation:
y = a*x + b
We have infinite pairs (x, y)
