Let x be the amount of weeks.

60 + 7x = 120
60 - 60 + 7x = 120 - 60
7/7x = 60/7
x = 8.571428571

Does anyone know how to do these? I don’t want the answers I need someone to explain how to do them so I can solve it. Thanks
ElenaW [278]

Hi! This type of equation is actully really simple to solve once you learn how so I'll only do a few and let you solve the rest.

To solve 3x + 6 = 18 you just need to remember that whatever action you do on one side of the equal sign you have to do on the other as well, and you just need to get the variable isolated on one side and the constant on the other.

So subtract 6 from both of the constants (6 and 18) to get to 3x = 12.

Then divide both sides by 3 to isolate x and you get x = 4.

To solve x/7 -9 = -7  you have to add 9 to both sides to get x/7 = 2. Then because it's a fraction with a denominator of 7 you multiply both sides by 7 to get x = 14.

To solve 8x - 2x = -36 you combine like terms to get 6x = -36 then divide both sides by 6 to get x = -6.

Hope this is what you were looking for and explained in an understandable way, if not I apologize. :)

Find the zero places of the quadratic function: y= x^2 + 5x + 6
andre [41]

The required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.

Given that,
An equation   y= x² + 5x + 6,
To determine the Zeros of the equation given above.

<h3>What is the equation?</h3>

The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.

Here, given equation is, y= x² + 5x + 6
Now, let y = 0
x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3 (x + 2) = 0
(x + 2) * (x + 3) = 0
x + 2 = 0    ;   x + 3 = 0
x = -2  and x = -3

Thus, the required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.
