Answer:
192 feet is the stopping distance at 48 mph.
Step-by-step explanation:
Set up the proportion 
x/75 = 2304/900 cross multiply to get 900x = 172800
172800 ÷ 900 = 192
x = 192
Answer:
Step-by-step explanation:
1.Distribute
12x - 66 + 15 =21
2.Add the numbers
12x-51=21
3.Add 51 to both sides of the equation
12x -51 +51 = 21+51
4.Simplify
12x=72
5. Divide both sides of the equation by the same term
12x/12 = 72/12
6. Divide the numbers
x=6
And you have your answer x=6
<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
Answer:
1 x=4
y=-1
2 has no solution
3 x=5y -/8 + 27/4
y= 54-8x/5
4x=y=0
5 x=2 y=1
