Answer:
x = 19
Step-by-step explanation:
3x - 3 = [6 (x - 10)]
3x - 3 = 6x - 60
3x - 6x = - 60 + 3
- 3x = - 57
- x = - 57/3
- x = - 19
x = 19
Answer:
x= -7
Step-by-step explanation:
Simplify both sides of the equation.
4(1−x)+2x=−3(x+1)
(4)(1)+(4)(−x)+2x=(−3)(x)+(−3)(1)(Distribute)
4+−4x+2x=−3x+−3
(−4x+2x)+(4)=−3x−3(Combine Like terms)
Add 3x to both sides.
−2x+4+3x=−3x−3+3x
x+4=−3
Subtract 4 from both sides.
x+4−4=−3−4
x=−7
The function in terms of the time (t) is t=d/r and the value of the time (t) for the given values is 5.
<h3>Linear Function</h3>
An equation can be represented by a linear function. The standard form for the linear equation is: ax+b , for example, y=2x+7. Where:
a= the slope
b=constant term that represents the y-intercept.
For the given example: a=2 and b=7.
In the exercise is asked the equation for the time (t) in the function of the distance (d) and the rate (r).
Thus, if d=rt, we will have t= d/r
Replacing the variables for the given values for finding t. The question gives:
distance (d) =40
rate (r) = 8
Thus, you will have t= 40/8. Then, t=5
Therefore, the answer is the fourth option.
