Answer: 4 : 2
Step-by-step explanation:
I am going to assume you want a ratio between number of tires to headlights which is
4 : 2
Answer:
-5 If it is one of your answers it will be -5
Step-by-step explanation:
If you take 10 and have 3 decrease every minute and did it for 5 minutes it will go 10 7 4 1 -2 -5 That is 5 minutes of the temperature decreasing by 3 I hope it is right.
Expand
simplify x - 5x + 35 to -4x + 35
subtract 35 from both sides
simplify -7 - 35 to -42
divide both sides by -4
two negatives make a positive
simplify 42/4 to 21/2
Answer: x = 21/2.
The greatest common factor between 64 and 24 is 8
Let's divide both terms in the expression by 8 and leave the expression in parenthesis...
Like this!
64x -24
8x - 3
Leave 8 we divided outside the parenthesis
Now we have this!
8( 8x - 3)
This is the distributive property form!
Alright...simple...showing all steps.. ;)
You have the equations...
2x+y=7
and
3x+5y=14
To be able to even solve for any of the variables...multiply the equations by...2...and..3...
2x+y=7----*3--> 6x+3y=21
and
3x+5y=14-----*2--->6x+10y=28
Thus,
6x+3y=21
-
6x+10y=28
=========
-7y=-7
y=1
Now, plug y back into any of the original equations....we'll use 2x+y=7 in this case....
2x+(1)=7
2x+1=7
-1 -1
2x=6
x=3
Thus, the point of intersection for these two equations is (3,1)
