Answer:
Uhh, I guess 24? I don't understand this question
Answer:
I'll explain
Step-by-step explanation:
For an inequality and equation to solve them is almost the same
A difference is that, in an inequality, if there is a negative, when you divde the sign will change (<,>,=,) Hope this helps.
Lets say x = 89.99 and y = 56.49
P% * x = y
P% = y/x
56.49/89.99 = 0.6277
0.6277 * 100 = 62.77
But because we are looking for how much off the sale is:
100% - 62.77%
= 37.23%
The sale price is 37.23% off.
7+3x-12x=3x+1
We will first make all the numbers which have x in go to the left.
So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.
Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.
So now it is much easier to figure out.
-12x=-6
Answer:
a = sqrt(c^2 - b^2)
see image.
Step-by-step explanation:
If you square both sides of the equation, you get the Pythagorean Theorem back again.
c = sqrt(a^2 + b^2)
c^2 = a^2 + b^2
Solve for a means to get a all by itself on one side of the equation. Subtract b^2 and then take the square root. See image.
