Step-by-step explanation:
Well its easy mean search a video in YouTube
there are two types for systems of question:
The method for elimination
The method for substitution
The elimination only that u have to do is found x or y hat are the sam,e number with different symbols ↓↓like this↓↓
- 7y + 3x = 45
7y + 12x = 33
the y is cancel and... u know the process..
But the method for substitution is different u only need to put the y en the problem and that's it, and when u found the valor of x u can solve for y ↓↓like this↓↓
4x - 2y = 24
y = x - 5
4 (x - 5) = 24
4x - 20 = 24
+20 +20
4x = 44
4x/4 = 44/4
x = 11
The property that justifies this statement is the Symmetric Property of Congruence.
<h3>What is symmetric property of Congruence?</h3>
The symmetric property of congruence states that If an angle is congruent to another angle, then the second angle is also congruent to the first angle.
A congruent geometric shapes are shapes having the same size and shape, or matching in size and shape and their corresponding angles are equal to each other.
If shape A is congruent to shape B and A= B , then B = A
Similarly,
If angle DEF is equal to angle HJK, then with the law of symmetry property of angle HJk is equal to angle DEF.

Answer:
Mass determines how fast a car can accelerate. Since a car accelerates slower with more adults, and faster with less adults, this means that the mass has a big impact on acceleration. Therefore, we can conclude that the mass determines how fast a car can accelerate.
A = L * W
A = 50
L = 2W
50 = W(2W)
50 = 2W^2
50/2 = W^2
25 = W^2
sqrt 25 = W
5 = W
L = 2W
L = 2(5)
L = 10 <==length is 10 yd
