100 POINTS!!!!!!! I WILL GIVE BRAINLIEST!
abruzzese [7]

Answer:

  • 8.4 miles

Step-by-step explanation:

Let the speed in the morning be s, then in the evening it is s - 4

<u>The distance is equal both directions:</u>

  • 45 min *s = 1 hr 10 min *(s - 4)

<u>Time in hours:</u>

  • 45*1/60*s = (1 + 10*1/60)(s - 4)
  • 3/4s = 7/6s - 7/6*4

<u>Multiply all terms by 12 to clear fraction:</u>

  • 9s = 14s - 56
  • 5s = 56
  • s = 56/5
  • s= 11.2 mph

<u>The distance is:</u>

  • 3/4*11.2 = 0.75*11.2 = 8.4 miles

How do you solve x^2-4X-12=0
Pepsi [2]
                                         x²  -  4x  - 12  =  0

Factor the left side:      (x + 2) · (x - 6)  =  0

The equation is true if either factor is zero.

If  (x + 2) = 0  then    x = -2 .

If  (x - 6) = 0  then     x = 6 .

Can someone give me the answers plz:)

Remark

There is no short way to do this problem and no obvious way to get the answer other that to solve each part.  

Solve

A

\dfrac{x + 1.6}{2} =\text{x + 0.1}                    Multiply by 2

x + 1.6 = 2(x + 0.1)                                         Remove the brackets

x + 1.6 = 2x + 0.1*2                                        

x + 1.6 = 2x + 0.2                                          Subtract x from both sides

1.6 = x + 0.2                                                  Subtract 0.2 from both sides  

1.6 - 0.2 = x                        

1.4 = x

Circle A

B

Subtract 2x from both sides.

3x - 2x = 1.4

Circle B

C

Remove the brackets.

4x + 6 = 2x - 6           Add 6 to both sides

4x + 12 = 2x               Subtract 4x from both sides.

12 = -2x                      Divide by - 2

12/-2 = x

x = - 6                         Don't circle C

D

I'm going to be very scant in my solution of this. You can fill in the steps.

3x = 4.2

x = 4.2/3

x = 1.4

Circle D
