7 0

4x+(3x2)+2=0
(3x2)+2= 8
Subtract 8 on both sides of equation.
4x= -8
Divide by 4 on both sides and your answer will be: x= -2

sergejj [24]

Answer:

Ben's rate is $\dfrac{1}{6}$ greater than Kate's rate.

Step-by-step explanation:

1. If it takes Ben 2 days to write reports, then his rate is $\dfrac{1}{2}$ of reports per day.

2. If it takes Kate 3 days to write reports, then her rate is $\dfrac{1}{3}$ of reports per day.

3. Ben's rate is

$\dfrac{1}{2}-\dfrac{1}{3}=\dfrac{3-2}{6}=\dfrac{1}{6}$

greater than Kate's rate.

- 3 + 3x = 2x – 13 <br><br> I have to use more characters...

DENIUS [597]

- 3 + 3x = 2x – 13

Bring -3 to the right side of the equation by adding 3 to both sides

(- 3 + 3) + 3x = 2x – 13 + 3

0 + 3x = 2x - 10

3x = 2x - 10

Bring 2x to the other side by subtracting 2x to both sides

3x - 2x = 2x - 2x - 10

x = -10

Check:

-3 + 3(-10) = 2(-10) - 13

-3 + (-30) = -20 - 13

-33 = -33

Hope this helped!

V (t)=32t <br> If a rock dropped off a bridge, how fast will it be falling after 3 seconds

kondor19780726 [428]

V(t) = 32t

when t = 3 seconds,

V = 32*3

V = 96

So velocity will be 96 units/s after 3 seconds.
