Answer:
x = 31/3
Step-by-step explanation:
4x+8+2x+20=90
4x+2x+8+20=90
4x+2x+8+20=90
6x+28=90
6x+28-28=90-28
6x=62
x = 31/3

Answer:
x=2, y=3
Step-by-step explanation:
First, graph both equations on a rectangular coordinate system (see attached screenshot). Then, simply figure out where these two lines intersect. Since they intersect at (2,3), x=2 and y=3.
Plugging these values in the equations for x and y, you can see if these are the correct answers:
(3)=3(2)-3, (2)+(3)=5
Since both of these are true, you have the right answer.
Hope this helps!
Answer:
Option C is correct
The ratio of green to red marbles is, 3 : 1
Step-by-step explanation:
As per the statement:
A bag contains 44 marbles, some red and some green.
⇒Total marbles = 44
If there are 11 red marbles.
then;
Green marbles = Total marbles - red marbles.
Substitute the given values we have;
Green marbles = 44 - 11 = 33
We have to find the ratio of green to red marbles.
Therefore, the ratio of green to red marbles is, 3 : 1
