I got B because you can add .4x and 6x together
Answer:
La suma de dos numeros es 57.Si el mayor de los dos números es 9 menos que el doble de los más pequeños, encuentre los dos números.
(Scroll Down for Answer!)
Step-by-step explanation:
3*y = 57 + 9 = 66
y = 66/3 = 22
x + 22 = 57
x = 57 - 22 = 35
Por lo tanto, los números son 35 and 22.
Answer:
dependent
Step-by-step explanation:
The given system is :
15x-18=3y
5x=y+6
Rewrite the equations in standard form to get:
15x-3y=18
5x-y=6
Multiply the bottom equation by 3.
15x-3y=18
15x-3y=18
Sub both equations:
0-0=0
0=0
We got an identity
The system is dependent because there are infinitely many solutions
Answer:
<J = 45
<L = 45
<M = 90
This is an isosceles right triangle
Step-by-step explanation:
The angles of a triangle add up to 180 degrees
<J + <L + <M = 180
2x+15 + 5x-30 + 6x = 180
Combine like terms
13x -15 = 180
Add 15 to each side
13x-15+15 = 180+15
13x = 195
Divide each side by 13
13x/13 =195/13
x =15
<J =2x+15 = 2*15+15 = 30+15 = 45
<L = 5x-30 = 5*15 -30 = 75-30 = 45
<M = 6*15 = 90
The triangle is a right triangle
Since two angles are equal, that means two sides are equal so it is an isosceles triangle.
This is an isosceles right triangle
