3( x - 1 ) = 2 x + 5
Expand 3(x-1) :
3*x - 3 x 1
3 x - 3 = 2 x + 5
Add 3 both sides :
3 x - 3 + 3 = 2 x + 5 + 3
3 x = 2 x + 8
3x - 2 x = 8
x = 8
hope this helps!
This is not my answer I found it from another brainly
From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.
Tony:
2x+3.5y=355
Rae:
2x+3y=320
Now you can solve the equations by subtracting Rae's equation from Tony's
.5y=35 solve for y and you get 70
Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:
2x+3(70)=320
x=55
Answer:
-6+x≤15
negative six: -6
plus: +
a number: variable (I chose x)
Less than or equal to: ≤ (an inequality)
fifteen: 15
G = 18.5. Add 1.5 to both sides, and calculate
Because n is a variable and a variable is serving that you can always change.
