Which method can't you use to solve this problem? x^2-47=0
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆A.) Factoring
Cannot factor, no common factors.
B.) Squareroots
C.) Quadratic Formula
the answer would be x=6
to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent
hope this helps :)
Answer:
21
Step-by-step explanation:
Let x = $1 bill
Let y = $5bill
<em>Translating the word problem into an algebraic equation;</em>
<em>For the total number of bills;</em>
.........equation 1
<em>For the total number of tips;</em>
..........equation 2
<em>*Solving the linear equation by using the substitution method*</em>
<em>Making x the subject in equation 1:</em>
.......equation 3
<em>Substituting "x" into equation 2;</em>
<em>Simplifying the equation, we have;</em>


y = 21 (For the $5 bills).
<em>Therefore, Anthony received 21 pieces of the $5 bills.</em>
To find x;
Substituting "y" into equation 3;

x = 26 (For the $1 bill).

Answer:
B
Step-by-step explanation:
You can divide the larger number by the smaller number for all of them and see if they all match. If they dont then its not porportional.
