The distance formula is distance(d) = rate(r) x time(t). In this problem we are trying to find the distance and we are given the rate which in this case is 66.8 feet per minute * 2 and the time is 30 minutes. We can substitute this into our equation we get:
D = <span>133.6 x 30. When we multiply this out we get D =  4008 ft.</span>

Easy question. giving brainliest<br> 7g+8(6g+3)=849<br><br> g=
vlabodo [156]

Answer:

g = 15

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    7*g+8*(6*g+3)-(849)=0  

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

2.1     Pull out like factors :

  6g + 3  =   3 • (2g + 1)  

Equation at the end of step  2  :

 (7g +  24 • (2g + 1)) -  849  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  55g - 825  =   55 • (g - 15)  

Equation at the end of step  4  :

 55 • (g - 15)  = 0  

Step  5  :

Equations which are never true :

5.1      Solve :    55   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2      Solve  :    g-15 = 0  

Add  15  to both sides of the equation :  

                     g = 15

Hope this helps

How do you write an equation of a line given y-intercept -8 and slope 3/4
Lostsunrise [7]

Answer:

y = \frac{3}{4} x-8

Step-by-step explanation:

You can us the equation y = m x + c to answer this question.

In ,

y = m x + c

m = slope

c = y - intercept

So, they have already given in the question that,

m = 3/4

c = (-8)

Therefore, you can simply put 3/4 and (-8) instead of m and c respectively like this.

y = m x + c

y = 3/4x - 8

Hope this helps you.

Let me know if you have any other questions :-)
