juan and debbie each earn 9 per hour at their "jobs." Debbie worked five hours more than juan during the week. if juan and debbi
Vaselesa [24]

Using a system of equations, it is found that Debbie worked 45 hours during the week.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount of hours worked by Juan.
  • Variable y: Amount of hours worked by Debbie.

Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:

9x + 9y = 765

Simplifying the expression by 9:

x + y = 85 -> x = 85 - y.

Debbie worked five hours more than juan during the week, hence:

y = x + 5.

Since x = 85 - y, we replace in the expression:

y = 85 - y + 5.

2y = 90.

y = 45.

Debbie worked 45 hours during the week.

Usimov [2.4K]

Given:

The equation is:

x^2+3x-4

Find-:

Binomials factor of the equation

Explanation-:

The quadratic equation,

x^2+3x-4

Solve for factor

\begin{gathered} =x^2+3x-4 \\  \\ =x^2+4x-x-4 \\  \end{gathered}

Then the factor is:

\begin{gathered} =x^2+4x-x-4 \\  \\ =x(x+4)-1(x+4) \\  \\ =(x+4)(x-1) \end{gathered}

So, the factor is x + 4

Mamie saved $161.25. This is 25% of the amount she needs to save, how much money does Mamie need to save?
babunello [35]
You would solve this by writing it as a porpotion. It would be 25/100=161.25/x. Then, you would multiply the 100 and 161.25, which would get you 16125, then you would divide this by 25, which would get you your answer : $645.
