Answer:

64

Step-by-step explanation:

The information can be written as:

Let Alex's number = x

Winnie's number = y

x = 1.75y

x = y + 48

Substitute 1.75y for x:

1.75y = y +48

0.75 y = 48

3/4 y = 48

y = 64

Winnie's favourite number = 64.

If mx=x+5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)
Ne4ueva [31]

Answer:c

Step-by-step explanation:

Given

m\left ( x\right )=x+\frac{5}{x-1}

and n\left ( x\right )=x-3

m of n is given by replacing x in m\left ( x\right ) by x-3

m\left ( n\left ( x\right )\right )=x-3+\frac{5}{x-3-1}=x-3+\frac{5}{x-4}

m\left ( n\left ( x\right )\right ) can take any value of x except x=4 because at x=4 function is not defined

and h\left ( x\right )=\frac{11}{x-4} is also not defined for x=4 and can take any value of x

4. Add one set of parentheses to make the expression equal
Sauron [17]

The expression that is equal to 2022 by adding a set of parentheses is 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12).

<h3>How to solve a long-expression problem?</h3>

In mathematics, parentheses are used to group a set of mathematical terms. In  a long-expression, like the one presented, using parenthesis implies:

  • The terms in the parentheses are solved separately from those outside the parentheses.
  • The terms in the parentheses are solved before solving those outside.
  • Moving the parentheses will affect the result of the whole expression.

Based on this, the expression that equals 2022 is:

  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

<h3>Let's solve it to prove this result</h3><h3 />
  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

First, solve the parenthesis first by dividing and then by adding.

  • 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (1 + 1)12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / 2

Now, let's solve this expression, the first step is to solve the multiplications.

  • 1728 + 144 + 144 + 12/2

Now, solve the division.

  • 1728 + 144 + 144 + 6

Finally, add everything.

  • 1728 + 144 + 144 + 6 = 2022
