What is the expanded expression form that is equivalent to 3(x+3y) ?
It is = 3x+9y
Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25
Is this what you were looking for?
Infinitely many solutions means that you have the same thing on both sides of the equation no matter what value of x you plug in, right?
We just need both sides to be 3x then, correct?
If a were equal to 3 and b were equal to 0, we'd have
3x = (3)x + 0
Which is essentially 3x = 3x
So that means a = 3 and b = 0 must work!
Let's say x = 5
3(5) = 3(5) + 0
15 = 15 + 0
15 = 15
That means that a = 3 and b = 0 is your final answer :)
Answer:
83
Step-by-step explanation:
the angle with 126 is supplementary and all the angles of the triangle are supplementary
180-126 = 54
54 + 43 = 97
180 - 97 = 83
